At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain Bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

2. Separation of Belgian Magic Star Diamond:

the beneficiation process of Belgian Magic Star Diamond generally includes preparation, roughing and cleaning. The preparation operations before beneficiation of Belgian Magic Star Diamond generally include crushing, screening, ore washing, grinding, hydraulic classification, etc. The purpose is to create good conditions for beneficiation in advance, so that the beneficiation can be carried out smoothly and obtain good results< Crushing

1.1. Crushing is the main preparation operation before the separation of Belgian magic star diamond primary ore. in the crushing stage, on the one hand, the coarse-grained ore should be fully dissociated, on the other hand, the crushing of Belgian Magic Star Diamond crystal should be reced as far as possible. In the process of ore crushing, the requirement of protecting crystal is more strict than crushing other ores. The crushing equipment is mainly jaw crusher, There are also gyratory crushers, hydro crushers, etc.

1.2. Screening

there are many places that need to use screening operation in Belgium Magic Star Diamond beneficiation. On the one hand, screening can timely separate the ore with appropriate particle size in the crushing stage, avoid excessive crushing of ore, rece power consumption and improve efficiency, It is also good for crystal protection: on the other hand, it can prepare for the next mineral processing operation. The screening equipment is the screening machine, the most commonly used is the vibrating screen, followed by the shaking screen.

1.3. Ore washing

the Belgian Magic Star Diamond placer and some primary ores contain a lot of clay minerals, It must be removed before mineral processing. Ore washing is the process of removing clay material from ore, including two stages of dispersing clay and separating the dispersed clay material from granular material. Commonly used ore washing equipment include high-pressure water gun, cylindrical ore washing machine, trough ore washing machine, etc.

1.4, The main purpose of grinding Belgian Magic Star Diamond ore is to dissociate all or most of the monomers of the fine Belgian magic star diamond in the ore, so that it can be recovered in the next step of mineral processing, Selective grinding can grind most ores to the required size, discard tailings and improve efficiency. Grinding operation is usually carried out in a rotating cylindrical mill. The mills include ball mill, rod mill and autogenous mill, The basic principle is that the medium (or ore itself) is used to grind the ore with impact phase.

1.5. Hydraulic classification

when the particle size of fine materials is separated, it is difficult to use the screening method, The basic principle of hydraulic classification is based on the difference of settling velocity in fluid e to the difference of particle size (or density). The main equipment for hydraulic classification is spiral classifier and hydrocyclone

4. The st at the exit of crusher equipment is very serious, and the block and powder materials from crusher directly affect the ore conveyor belt. Some substances splash or roll on the ground, and a thick layer of materials is accumulated on the ground. Part of powder materials are in the air, which brings a lot of inconvenience to proction. In this process, the material enters the plate feeder and the plate feeder enters tkpc20. And a hammer crusher, the crusher directly exports ore to the belt machine. Due to the crusher proction capacity is very large, 600 tons per hour, export logistics is also very large, resulting in st and splash
our analysis shows that the root cause of the above phenomenon is the mping caused by the lack of buffer in octagonal flow. Therefore, the following improvements can be made: a temporary garbage can is established between the crusher outlet and the ore belt, and the st collector is temporarily received. Between the temporary Ben, the belt and a valve. Then a material flow control valve is set in the valve. Setting temporary storage is to buffer the influence of large flowing materials; The material flow control valve can stabilize the export logistics; The st collector in the temporary warehouse can make part of the fine powder be treated in the early stage of the temporary storage, rece the outlet st, and also help to improve the service life of the belt. In this improvement, completely solved the st flying and material splashing point to the workshop proction and management, brought great convenience. In the process of crusher work, there may be some other problems, crusher common problems summary and troubleshooting, but also need to pay attention to time, provide crushing equipment efficiency.

5. Classifier:
the classifier is widely used in ore dressing plant and ball mill to form a closed cycle and separate ore sand, or used in gravity dressing plant to grade ore sand and fine mud, and in metal dressing process to grade ore pulp particle size, as well as desliming and dewatering in ore washing operation. The machine has the characteristics of simple structure, reliable operation and convenient operation
working principle:
the spiral classifier is based on the principle that different solid particle sizes and specific gravity result in different settling velocity in liquid, fine ore particles float in water and overflow, and coarse ore particles sink at the bottom of the tank. It is a kind of classification equipment for mechanical classification by pushing the screw upward to discharge. It can filter the powder from the mill, and then screw the coarse material into the feed port of the mill by using the screw, and discharge the filtered fine material from the overflow pipe. The base of the machine is made of channel steel and the body is made of steel plate by welding. The inlet head, shaft head and pig iron sleeve of the spiral shaft are wear-resistant and rable, and the lifting device can be divided into electric and manual modes.
the relationship between the width of the groove and the processing capacity of the spiral classifier:
the width of the groove has a great relationship with the discharge speed and discharge volume of the overflow proct, and the width of the groove makes the overflow discharge speed faster, so the possibility of coarse particles discharging with the overflow is greater. But on the other hand, the wider the trough is, the larger the settling area of the ore will be, which is easy to settle. So the width of the trough has little influence on the classification effect, but it will affect the processing capacity of the classifier. If the width of the trough is large, the processing capacity will be large; On the contrary, the processing capacity is small. Therefore, the tank width of the classifier should be suitable for the processing capacity of the mill<
spiral classifier structure:
the classifier is mainly composed of transmission device, spiral body, tank body, lifting mechanism, lower support (bearing bush) and discharge valve.

6. Separation of diamonds:
the mineral processing flow of diamonds generally includes preparation, roughing and cleaning. The preparation operations before mineral processing generally include crushing, screening, ore washing, grinding, hydraulic classification, etc. The purpose is to create good conditions for mineral processing in advance, so that the separation operation can be carried out smoothly and obtain good results< In the crushing stage, on the one hand, the coarse-grained ore should be fully dissociated, on the other hand, the crushing of diamond crystal should be reced as much as possible. In the process of ore crushing, the requirement of crystal protection is more strict than that of crushing other ores. The crushing equipment is mainly jaw crusher, but also rotary crusher On the one hand, screening can timely separate out the ore with appropriate particle size in the crushing stage, avoid excessive crushing of ore, rece power consumption, improve efficiency, and also have benefits for crystal protection; on the other hand, it can prepare for the next step of mineral processing. The screening equipment is screening machine, The most commonly used is vibrating screen, followed by shaker screen.
1.3. Ore washing
diamond placer and some primary ores contain a large number of clay minerals, which must be removed before beneficiation. Ore washing is the process of removing clay materials from ores, including two stages of dispersing clay and separating the dispersed clay materials from granular materials Grinding
grinding is the continuation of the crushing process, which means that in mechanical equipment, the particle size of the ore is further reced by the impact and grinding of the medium and the ore itself, In addition, according to the difference of wear resistance between diamond and gangue minerals, selective grinding can grind most of the ore to the required size and discard tailings to improve efficiency. Grinding operation is usually carried out in a rotating cylindrical mill. The mills include ball mill, rod mill and autogenous mill, The basic principle is that the medium (or ore itself) is used to grind the ore with impact phase.
1.5. Hydraulic classification
when the particle size of fine materials is separated, it is difficult to use the screening method, The basic principle of hydraulic classification is based on the difference of settling velocity in fluid e to the difference of particle size (or density). The main equipment for hydraulic classification is spiral classifier and hydrocyclone

7. At the same time, the mining machinery instry is dominated by crusher instry, so the development of crusher instry will determine the development of the whole mining machinery instry. In addition, the mobile crushing station is also the preferred equipment for construction waste treatment and open-pit coal mining. Liming machinery with a devout fine strict and harmonious concept of customer service, willing to work hard for the prosperity of the country, unremitting efforts!. Today, with the rapid development of urbanization, the amount of construction waste in China has accounted for 30% - 40% of the urban waste. If the untreated construction waste is directly transported to the outskirts or villages and disposed in the way of open-air stacking or landfill, it will not only consume a lot of land resources, but also occupy funds such as garbage clearance and transportation fees, In the process of clearing, transportation and stacking, the problems of st and st flying will cause serious environmental pollution and damage the ecological environment. According to our experience, the construction waste in a city is generally piled up in one place for centralized treatment, and there is no need for treatment equipment to deal with construction waste everywhere. Waste procts (including metal, bamboo, wood, various packaging materials, wood, plastic, glass, etc.). The waste that may have pollutants can be used as renewable resources after sorting. In order to recycle construction waste, it is necessary to use professional construction waste treatment equipment<

the real and effective utilization of construction waste involves not only technical problems, but also social, economic and environmental problems, and needs the extensive participation of the whole society. Construction waste mainly includes waste wood, tile, concrete, steel and metal components. Liming machinery will introce a new type of mobile construction waste treatment equipment to solve the problem of construction waste accumulation. From then on, it is no longer a myth that waste becomes treasure. In the process of urbanization, as a proct of urban metabolism, the increase of construction waste has brought a great burden to the development of the city. For a long time, China has not paid attention to the recycling of construction waste, but just transported them to the suburbs for stacking or landfill. However, with the continuous increase of construction waste, energy conservation and environmental protection are vigorously advocated, China is really concerned about construction waste treatment. In the process of construction waste treatment, the government also has strong support, and the government has also given corresponding subsidies. As one of the main varieties of building materials instry, the output of sand and stone is also rising sharply, which also drives the whole instry from backward and even some original proction state to the direction of instrialization. The PCL vertical impact crusher (manual sand making machine) proced by Zhengzhou Liming mechanical equipment Co., Ltd. uses the rocks put into the crusher to impact each other and break themselves. For example, diamond mostly uses its hardness and luster; Mica can be used as an important raw material for electronic instry because of its insulation and transparency; Crystal is made use of its optical and piezoelectric properties and so on. Limestone and cement clinker were mixed and grinded according to different proportions. The particle size distribution, specific surface area and cement properties of the mixed grinding procts were studied. In the field of engineering, efficient sand making machine is an ideal proction equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate; In the field of mining, it is widely used in the pre grinding process, which can proce a lot of fine ore and rece the high cost grinding load. It provides more high-quality and efficient equipment with international advanced level for the development of coal, metal and non-metal mines, and meets the needs of national economic development for energy and raw materials. Nowadays, driven by the development of domestic basic instry and basic liming, the market demand of sand making machine is booming, which promotes the technological progress of the whole sand making machine instry. A number of major new procts with independent intellectual property rights have emerged, such as 5x series new sand making machines, VSI series sand making machines, PCL series sand making machines proced by Zhengzhou Liming mechanical equipment manufacturing Co., Ltd, China's mining machinery instry is playing a more and more important role in the international mine engineering dawn<

300 cubic meters of sand and gravel proction line, cobble sand machine, but in the dawn of the road, the dawn of the subgrade is very important, the subgrade is the main body of the formation of the highway line, is the foundation of the pavement, and together with the pavement bears the weight of traffic. The crushing, screening and washing equipment will be used in the proction of granite, basalt and other building materials aggregate. I believe the excellent quality of Zhengzhou Liming mining machinery and mining machinery crusher procts will bring great benefits to Shandong Liming!. A building materials Co., Ltd. in Loudi City, Hunan Province has invested in a machine-made sand proction line for Expressway in Liming. The raw materials for crushing are river pebbles in the local river. The design capacity is 1500 tons of river pebbles per day, and the particle size of finished materials is 0-31.5mm, Liming mine designed three-stage crushing process: gzt1148 vibrating feeder → PE750 * 1060 jaw crusher → psg1300 cone crusher → VSI vertical shaft impact crusher → 3yk2160 circular vibrating screen → two spiral sand washing machines → HX series fine sand recovery machine system. In order to achieve energy conservation and emission rection, and make rational use of construction waste resources, Shandong Province issued the notice of the general office of Shandong Provincial People's Government transmitting the opinions of the provincial economic and Information Commission and other departments on further improving the comprehensive utilization of construction waste, which has laid a good foundation for the comprehensive utilization of construction waste into new building materials from the technical and policy aspects. The ingenious air flow self circulation inside the whirl chamber eliminates the st pollution. The mobile crusher proced by liming Mining Machinery Co., Ltd. has the advantages of flexibility, convenience, strong mobility, saving a lot of capital construction and relocation costs. It can crush materials on site and move with the advance of raw material mining face, thus greatly recing the transportation costs of materials. Liming Mining Machinery Co., Ltd. specializes in the proction of crushing, screening, conveying and other rock crushing and mineral processing equipment, Based on the company's original technology, the company has optimized the combination and launched two new large series and three small series of mobile crushing and screening equipment, including crawler crushing station and tire crushing station. Each large series has three series of mobile crushing and screening stations, which can fully adapt to various situations of mobile crushing and screening, Truly create more new business opportunities for customers and rece proction costs. After long-term research, Zhengzhou Liming Mining Machinery Co., Ltd. has developed the comprehensive Liming project of building reuse of renewable resources - tire type mobile crushing station and fixed construction waste crusher. By classifying waste and earth rock and crushing all waste to a certain specification, it has made renewable building materials that meet the requirements of national environmental protection and quality, which are widely used in road construction Foundation and other aspects. So as to achieve the double combination of social and economic benefits, and enterprises out of a common development path. The poor lubrication of cone crusher is mainly reflected in the important internal lubrication parts: between the straight bushing and the eccentric bushing, between the main shaft and the inclined bushing, between the body spherical surface and the bowl bearing bush. The collector can be mixed with neutral oil to form an emulsion and then added to the slurry. The grinding system, because it takes up more than half of the power consumption in cement proction, is deeply concerned. Due to the low energy utilization rate of the traditional ball mill grinding process, 70% of the power consumption in cement proction is used for the grinding of raw meal and cement. Therefore, energy saving is the basic task of reforming the grinding process. Based on this, the high-efficiency fine crusher is increasingly showing its long-term development advantages. Whether it is the selection of railway ballast or the pouring of concrete, it needs high-quality sand making machine www.xinshashebei.com The equipment can proce qualified sand.

According to the main development trend of non-metallic mineral exploitation and utilization in the world and the current situation of non-metallic mineral resources and utilization in Henan Province, the development of non-metallic mineral instry in Henan Province must serve the economic construction of Henan Province and provide high-quality non-metallic mineral raw materials for the development of instry, agriculture and high-tech instry in Henan Province; At the same time, we should focus on the domestic and international markets, expand domestic and foreign sales, and increase the fiscal revenue of Henan Province. Give full play to the role of science and technology as the primary proctive force, strengthen the close cooperation between scientific research institutions, especially the National Research Center for comprehensive utilization of non-metallic mineral resources, luonai Institute, Sanmo Institute and other scientific research institutions, factories and mines, jointly tackle key problems, form a number of leading and exemplary achievements, and change the backward situation of only procing raw materials and primary processing procts as soon as possible, We should accelerate the transformation of non-metallic mining instry from simple labor-intensive to technological development, to the instrial development direction of deep processing procts, improve the economic benefits of factories and mines, and turn resource advantages into economic advantages

the nonmetallic minerals listed below are mainly developed in Henan Province from the 10th five year plan to 2010: ① kyanite, andalusite, sillimanite; ② Xinyang Shangtianti bentonite, perlite, zeolite, tuff and other non-metallic minerals; ③ Bauxite and refractory clay; ④ Graphite; ⑤ Rutile; ⑥ Sericite; ⑦ Nepheline syenite; ⑧ Natural alkali

in Henan Province, the following instries should be developed

In addition to large reserves, Henan Province also has a complete range of refractory minerals, including high alumina clay, hard clay (coke gem), soft and semi soft clay, bauxite, etc., as well as kyanite, bauxite, etc., which can be used to proce high-quality and special refractory materials Sillimanite, andalusite, forsterite and so on. At present, a proction scale of 2.5 million tons of raw ore and 1.5 million tons of refractory has been formed. However, the resources available for development and utilization are seriously insufficient, because there are more reserves of low-grade ores and less high-grade ores with high quality. Some foreign trade export units and refractories factories purchase high alumina mature materials with Al < sub > 2 < / sub > o < sub > 3 < / sub > content more than 85%, and aluminum factories only collect rich ores with Al / Si ratio greater than 8-10, which will inevitably lead to indiscriminate mining, with mining rate of only 30% - 40%, rapid rection of high-quality high alumina clay, destruction and waste of resources. In the face of this phenomenon, in addition to strengthening the administrative management of government departments, conscientiously implementing the "mineral resources law of the people's Republic of China" and making overall planning for resource development, it is more important to strengthen the research on Beneficiation and purification process of low and medium grade ores (al < sub > 2 < / sub > o < sub > 3 < / sub > content below 60%) to supplement the shortage of high-quality and high-grade ores, It not only ensures the sustainable and healthy development of refractory instry, but also ensures the demand of High Alumina ore for high alumina cement and alumina proction

The key to improve the quality of refractory clay mineral procts in our province is to rely on the progress of science and technology and improve the proction technology and equipment level of mining, beneficiation and calcination. In order to ensure the stability of ore supply and the quality of ore, measures such as homogenization should be taken to rece the mixed grade in the mining process. Improving calcining furnace and adopting advanced calcining furnace are important measures to improve the quality of refractory clay clinker. In the calcination proction, we should graally eliminate some earth shaft kilns with small diameter and small height difference between inlet and outlet, transform and popularize large calcination shaft kilns with diameter greater than 3.0m and height difference between inlet and outlet of 10m, and build some downdraft kilns with the diameter of 100m < sup > 3 < / Sup > or above or 0.3m in places where conditions permit × 60m rotary kiln, so that the quality of calcined clinker continues to improve, in order to enhance market competitiveness

depending on the progress of science and technology, the refractory clay proct structure of our province should be updated. High quality high alumina clay resources (DUJIAGOU, JIAJIAWA, etc.) should be further processed to proce high quality high alumina hard refractories such as magnesia alumina spinel and mullite

In view of the current situation of low concentrate grade, low recovery and poor economic benefit, it is necessary to strengthen the research on "three stone" beneficiation process. The concentrate grade of Kyanite in acidic pulp beneficiation process is higher than that in alkaline pulp beneficiation process, but the equipment is seriously corroded. Desliming operation takes away part of fine Kyanite and reces its recovery. The reagent system of alkaline pulp beneficiation process is more strict than the former, which has poor adaptability to the ore. in order to ensure the concentrate grade, sometimes the grade of the selected ore has to be increased, thus increasing the beneficiation cost. There are similar problems in the processing of sillimanite and andalusite, so it is very important to study the "three stone" processing technology in Henan Province

In the future, we should take Yinshan kyanite, Neixiang, Zhenping, Tong sillimanite and Xixia andalusite as the development objects, focus on the research on the technological characteristics of "three stone" minerals, and the comprehensive utilization of quartz, mica, garnet and other major associated minerals, so as to turn the resource advantages of "three stone" into economic advantages. In short, China's high aluminum mineral development and utilization base should be formed in Nanyang area, Henan Province, and its procts will occupy an important position in domestic and foreign markets

at present, the "three stones" in our province are mainly mining rich ore, high-quality ore, and selling beneficiation concentrate after beneficiation treatment, and the research on the proction of special refractory procts with them needs to be strengthened. It should be developed in the direction of high-grade series of andalusite brick, sillimanite brick and amorphous refractory. Increase the proportion of high-quality and high-grade refractory procts with high added value, and change the situation of only selling raw materials and low-grade procts

in order to meet the development requirements of domestic metallurgy and other high-temperature instries, and increase its share in the international market, a batch of high-quality synthetic refractory materials and high-efficiency procts with high technology content, good market prospect and instrialization should be developed as soon as possible, such as sintering materials, electric melting materials, rection nitriding materials, high-quality amorphous refractory materials, etc

to build a number of high-quality and efficient refractory raw material bases which are representative in technology and radiation in economy, and can drive related instries and have a certain scale. Such as thousand ton slide plate, thousand ton continuous casting nozzle, thousand ton vent plug, thousand ton high quality kiln furniture, thousand ton new unshaped refractory, thousand ton new century coke oven silica brick proction base

By adjusting the proct structure, the proportion of ordinary refractory procts decreased to less than 40%, the proportion of amorphous refractory materials increased to more than 35%, and the output value of high-quality and efficient refractory materials accounted for more than 70%. We will cultivate a number of leading enterprises with advanced management, strong technological innovation ability and annual output value of 100-500 million yuan

Second, strengthen the comprehensive utilization degree of Shangtianti non-metallic minerals, and strengthen the development of raw ore deep processing instry. Among them, perlite, bentonite, zeolite, tuff and other instrial reserves of large, good quality has been well-known at home and abroad. The mining area has a good economic, traffic and geographical environment. Although the mine has been developed for many years, the resources have not been reasonably utilized. Basically, the raw ore is sold, and the economic benefit is very poor. In order to get rid of this situation, we must fully and rationally develop and utilize all kinds of minerals in Shangtianti, strengthen scientific experiment and research, and expand the varieties and application fields of various deep-processing procts

The first is perlite, which is the main raw material of lightweight building materials. The rapid development of the construction instry puts forward higher requirements for building materials, which need a large number of new building materials with high strength, light weight, good heat and sound insulation performance, expanding the use area and improving the construction progress. According to the demand of construction market, the following procts should be developed: light perlite interior wall panel, light perlite exterior wall panel, light perlite wall block, perlite ceiling decorative panel, high-grade perlite roof insulation brick and tile, etc. To develop these procts, we should pay attention to solve the following technical problems

The first is to transform the existing perlite expansion furnace or introce a new type of expansion furnace. At present, the expansion ratio of the expansion furnace used is small, the - 60 mesh perlite can not be put into the furnace, the proction efficiency is low, and the pollution is serious, especially the glass shell perlite beads which meet the requirements of the construction instry can not be expanded. However, the Japanese bought a large number of Shangtianti perlite sand and proced various sizes of glass shell perlite beads, which were made into high-grade light-weight building boards of various colors

The second is to strengthen the research on comprehensive utilization of perlite powder and expand its application scope. Especially the utilization of - 60 mesh mineral powder. In addition to improving and manufacturing the new expansion furnace and expanding the size range of the slag powder, it is necessary to strengthen the experimental research on the silicon sources used as ceramic raw materials, perlite foam procts, filter aids, raw materials, abrasives, fillers and chemical procts, so as to solve the problem of resource waste and environmental pollution. p> The third is to develop the proction process of perlite plate. From preparation, mixing, molding, curing, drying to packaging and warehousing, a set of efficient, low-cost and complete proction process is formed, which completely changes the current backward proction mode of manual operation

Fourthly, it is necessary to develop a new and practical early strength curing adhesive, which is a necessary material for the proction of perlite plate. This adhesive must have the characteristics of good bonding effect, firmness, weather resistance, non-toxic and low price

In addition, new uses of perlite have been found. For example, as adsorbent: animal feces fast deodorization, activated with hydrochloric acid or sulfuric acid, used for purification of wastewater and waste; As carrier material: it is used as carrier of insecticide and herbicide, and it still has fluidity after reabsorption. It can also be used for perlite cement mortar, which has the characteristics of flame retardant and good insulation, and is 60% lighter than conventional cement mortar; If reinforced fiber is added, the anti cracking strength is high, and the perlite cement slurry is easy to use. Perlite powder is a kind of rubber and plastic filler with better quality

The main proct of Shangtianti bentonite ore is - 200 mesh calcium base powder after fine grinding of raw ore, which has poor technological performance and low economic benefit. In order to completely change the backward situation of relying mainly on the proction of - 200 mesh calcium based powder, we must first solve the problems of bentonite purification technology and equipment. Only the purified raw materials can be processed into high value-added procts. Aiming at the purification procts with different content of montmorillonite, organic bentonite, lithium-based bentonite, high-efficiency activated clay series procts and high-quality foundry clay were developed

At present, the zeolite ore in Shangtianti is mainly used as cement raw material, so its application in agriculture, environmental protection and other fields should be strengthened

the tuff of Shangtianti has high iron content, so it can be used as glass material instead of soda ash after removing iron

The Shangtianti non-metallic deposit is a variety of non-metallic deposits, which is a unique advantage. The mining area has a good economic, traffic and geographical environment, and has a certain foundation after years of development. It is necessary to strengthen the investment in Shangtianti mine, organize scientific and technological research, reform and update old equipment, focus on the proction of market-oriented deep processing procts, and graally build Shangtianti mine into a base for the comprehensive development and utilization of non-metallic mines in China

Graphite is one of the dominant non-metallic minerals in Henan Province, mainly distributed in the mountainous areas of Western and southwest Henan Province, with abundant reserves. Among them, Lingbao flake graphite ore and Xixia cryptocrystalline graphite ore are in the middle

Kaolin calcination processing technology belongs to the category of non-metallic mineral processing. The first is beneficiation, crushing the ore and grinding it into powder below 325 mesh. Then, the powder is sent to the pulp barrel for mixing and beating with water and dispersant, and the superfine damage is carried out to 4500-6000 mesh; Then the superfine damaged slurry is dried and dispersed, and sent to the calciner for calcination. When calcining, 1-3% of the total amount of whitener is added. The whitener is composed of clean coal, sodium sulfate and sodium chloride, and is mixed according to the proportion of 10 ∶ 0.3 ∶ 0.2

the calcination temperature is 970-990 ℃, and the calcination time is 30-40 minutes; Finally, the packaging was broken up to make procts. The whiteness of kaolin calcined by this technology can reach 90-95, and the particle size can reach 4500-6000 mesh. The high whiteness and superfine calcined kaolin procts are mainly used in papermaking, high-grade coatings and other instrial fields. In order to satisfy the higher fineness requirements of kaolin in papermaking, plastic and rubber procts instries, it is necessary to add the fineness of kaolin, and then further improve the quality of procts

The superfine grinding process mainly includes grinding and stripping, high-pressure extrusion and airflow destruction. Kaolin grinding equipment generally choose Raymond grinding equipment or vertical grinding machine. Raymond mill is also called Raymond mill. It is mainly suitable for various kinds of mineral powder preparation, coal powder preparation, such as kaolin, gypsum ore, coal and other materials of fine powder processing, so its use in kaolin proction line is indispensable
