Turbine feeder

1. THP (turbo high performance). It is a new cryptocurrency based on proof of capacity (hereinafter referred to as POC). Its main feature is to use hard disk as a consensus participant, rece the consumption of power resources by cryptocurrency, lower the threshold of participation, make its proction mode more decentralized, and more secure and reliable, so that everyone can participate in the mining of cryptocurrency, and generate credit and value through mathematical algorithm and distributed mining
pow (proof of workload): the pow mechanism relies on machine computing power to perform mathematical operations to obtain digital currency. Whoever has high computing power can proce more digital currency. To get rich through labor, more workers will get more (BTC is the mechanism of pow mining)< But there are fatal shortcomings:
1. The cost of mining machinery and equipment is expensive (ranging from tens of thousands to hundreds of thousands), and the depreciation rate of equipment is high
2. The equipment costs a lot of electricity (high cost)
3, not really centralization (if you are rich enough, you buy lots of mines, your computing power is large, when the amount of computation is greater than 50%, the whole network has the final say that it will cause autocracy).

2. When it comes to professional technology, of course, it belongs to the alien miner. The 52T miner developed by the alien miner has more than three times the power of the market model, but its power has not been greatly improved because it uses quantum energy-saving technology, uses the characteristics of superconcting materials in quantum mechanics to release the quantum energy of finishing electrons, and uses the turbine to conct microwave vibration to eliminate the interaction between molecules and atoms, So that the positive and negative current can be balanced transmission, rece resistance, control power consumption, achieve the effect of power saving.

4. The fun mole should be PI VIX.

5. One third of the money goes to business
one third of them invest in robust bank funds
one third of foreign exchange investment in gold and silver with high returns
in a word, don't put all the eggs in one basket!!!

6. 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.

There are few single mineral rocks and ores with important economic value in nature. Even single mineral rocks contain various impurities. The properties of minerals are not all available. Mineral processing is actually a process of "restraining disadvantages and exerting advantages"

There are four stages in the process of mineral processing: (1) crushing grinding; ② Beneficiation purification; ③ Superfine grinding; ④ Surface modification. For a particular mineral, the above process does not need to be completed completely, nor does it need to follow a strict sequence, depending on the mineral to be processed and the final proct, economic and environmental benefits

Crushing grinding crushing and grinding is the operation of recing the particle size of mineral raw materials, in which the rection to 5mm is called crushing, and the further fine crushing operation is called grinding. The fineness of grinding should be determined according to the results of process mineralogy research and experiments. Its purpose is to achieve monomer dissociation of useful minerals and gangue minerals in the ore, and provide materials with appropriate particle size and shape for subsequent beneficiation operations, or provide materials with appropriate particle size for subsequent ultra-fine grinding, or directly provide general powder procts. Crushing and grinding may be carried out in air medium (dry method) and water medium (wet method), usually by crushing screening operation and grinding grading operation. Crushers and sieves are mostly operated in combination, and mills and graders often form a closed cycle. They are the main mechanical equipment of crushing workshop and grinding and dressing workshop. The crushing equipment includes jaw crusher, cone crusher, roller crusher, impact crusher, hammer crusher, etc., and the screening equipment includes vibrating screen, bar screen, etc. Grinding equipment includes ball mill, rod mill, Raymond mill, column mill, high pressure roller mill, etc. Classification equipment includes mechanical classifier, hydraulic classifier, separation classifier, etc

The purpose of beneficiation purification operation is: (1) to separate useful minerals from gangue minerals and enrich useful minerals; (2) to separate useful minerals from gangue minerals; ② The harmful impurities in useful minerals are removed to purify them; ③ Recovery of associated useful minerals and comprehensive utilization of mineral resources. After beneficiation, three procts, concentrate, middling and tailings, can be obtained. The final proct with high content of useful minerals and suitable for smelting and processing is called concentrate. The intermediate proct obtained in the process of separation, which needs further treatment, is called middling. After separation, the proct with low content of useful minerals and no further treatment (or not suitable for further treatment technically and economically) is called tailings

The most commonly used beneficiation purification methods are as follows:

(1) gravity beneficiation (referred to as gravity beneficiation) gravity beneficiation is a method to achieve separation according to the movement speed and trajectory of minerals with different relative density (or density) in the medium (water, air or heavy medium). Gravity beneficiation has the advantages of large capacity, simple, reliable and low cost. It is widely used to separate metal minerals with relatively high relative density of rare metals (tungsten, tin, titanium, zirconium, niobium, tantalum, etc.), precious metals (gold, platinum group), and ferrous metals (iron, manganese, etc.). It is also used in the preconcentration of non-ferrous metals (copper, lead, zinc, etc.) and the gravity separation of non-metallic minerals (such as quartz and mica). In fact, hydraulic classification, wind classification and ore washing are also special cases of gravity beneficiation. Gravity separation operation is carried out in various types of gravity separation equipment, the main equipment are jigger, shaker, centrifugal concentrator, chute, heavy medium concentrator, etc

(2) flotation flotation, also known as froth flotation, is based on the wettability of the mineral surface, adding appropriate flotation reagents in the pulp, procing a large number of scattered bubbles in the flotation machine and adhering to the selected minerals, and floating on the surface of the slurry with buoyancy buoyancy to separate it from other minerals. The flotation method is widely used. Although the grinding fineness is required to be high and the beneficiation cost is high, the beneficiation efficiency is high and can be used to treat most ores. In nature, only a few minerals have good natural floatability (such as graphite, natural sulfur, molybdenite, talc, etc.), but most minerals have poor natural floatability. In order to realize the flotation separation of minerals, it is necessary to artificially control the wettability of mineral surface and enlarge the difference of floatability between minerals. In the process of flotation, the use of flotation reagents to change the surface properties of minerals is a necessary means to control the flotation behavior of minerals. Through the use of flotation reagents, the application scope of flotation process can be expanded, making it suitable for most minerals. Flotation reagents are generally divided into three categories: collector, frother and regulator. Flotation equipment includes mechanical agitation flotation machine, aerated mechanical agitation flotation machine, charged (pressurized) gas flotation machine and gas separation flotation machine

(3) magnetic separation minerals are divided into strong magnetic minerals, weak magnetic minerals and non-magnetic minerals. Magnetic separation is a mineral separation method based on the difference of magnetic properties of minerals in the ore and in the uneven magnetic field. Magnetic separation is mostly used for magnetic ferrous metal oxide minerals, such as magnetite, vanadium titanomagnetite, hematite, ilmenite, and also for pyrrhotite. For non-metallic minerals, magnetic separation is mainly used for the removal of impurities, so that the minerals to be purified, such as kaolinite, nepheline, feldspar, usually require the content of iron oxide impurities below a certain value (of course, the lower the better), magnetic separation has become an economic and efficient purification method. Magnetic separation equipment can be classified into permanent magnet and electromagnetic according to magnetic source, dry type and wet type according to operation mode, belt type, cylinder type and roller type according to separator form, and low magnetic field magnetic separator, high magnetic field magnetic separator and high gradient magnetic separator according to magnetic intensity and gradient

(4) chemical beneficiation and chemical purification chemical beneficiation is the method of extracting useful components from ore or removing harmful impurities in ore or mineral by chemical action, which can achieve the effect that mechanical beneficiation is difficult to achieve, but the cost is relatively high. Chemical beneficiation purification method includes the following methods: roasting, acid-base treatment, leaching, solvent extraction, ion exchange, chemical bleaching, etc., and a variety of methods can be used together, or combined with mechanical beneficiation method. For example, gold and silver can be extracted by dissolving gold and silver in mercury and cyanide solution; Acidic copper oxide and natural copper are leached with sulfuric acid to form copper sulfate solution, which is replaced by iron to form sponge copper; Hematite and limonite are mixed with proper amount of carbon and roasted to 570 ℃ to form magnetite, and then the concentrate is selected by magnetic separator. For non-metallic minerals, whiteness is an important index. The reason for its coloration is that it contains Fe < sub > 2 < / sub > o < sub > 3 < / sub > particles and cannot be mechanically selected. Sodium dithionite can be used to rece Fe < sup > 3 + < / sup > to soluble ferrous sulfate and remove it, so as to bleach the minerals

In addition, there are mineral processing methods based on the conctivity, friction coefficient, color and luster of minerals, such as electric separation, friction separation, photoelectric separation and manual separation

In general, d < sub > 97 < / sub > ≥ 10 μ M (also defined as d < sub > 90 < / sub > ≥ 10 μ m) The powder material is called "superfine powder". Now the latest mill can proce 0.25 μ M. Superfine powder has a series of special application properties, such as high surface activity, high chemical reaction speed, high solubility, low sintering temperature and high strength of sintered body As a composite material, it has good reinforcing performance and unique electrical, magnetic, optical and rheological properties

The application of ultra-fine powder began after the Second World War, especially in the past 20 years. With the rise of modern high-tech instry characterized by information technology, microelectronics, new materials, new energy, aerospace, biology, environmental protection technology, the understanding of the special characteristics of ultra-fine powder and the rapid development of ultra-fine powder processing technology, Ultra fine mineral powder has been widely used in modern instry and high-tech new materials. The main application fields are high-tech ceramics, ceramic glaze, microelectronics and information materials, plastics, rubber and composite fillers, lubricants and high-temperature lubricating materials, fine abrasives and friction materials, paper coatings and fillers, paint pigments and special coatings, biochemical and pharmaceutical materials, aerospace sealing materials, cosmetics, etc

up to now, the main methods of superfine grinding are mechanical methods, including pneumatic grinding with high-speed airflow impact; The impact type superfine pulverizer uses high-speed mechanical rotary impact and shear action; Using friction grinding function of stirring ball mill, vibration ball mill, rotary ball mill, planetary mill; Colloid mill using shear force; High pressure roller mill using compressive stress; And jet crusher with high pressure jet impact. The function of this equipment is to improve the grinding efficiency and prevent over grinding, and to rece the agglomeration of ultrafine particles in the grinding process, so as to ensure the fineness and particle size distribution of the powder. There are two types of superfine powder classifier, one is dry air cyclone classifier and turbine air classifier, the other is wet hydrocyclone, horizontal spiral centrifuge and sedimentation centrifuge

Surface modification mineral surface modification refers to the treatment of mineral powder surface by physical, chemical, mechanical and other methods. According to the needs of application, the physical and chemical properties of the powder surface are purposefully changed, such as surface crystal structure and functional groups, surface energy, surface wettability, electrical properties, surface adsorption and reaction characteristics, so as to meet the needs of modern new materials New process and new technology development needs. Surface modification provides a new technical means for developing the properties of mineral procts, improving their use value and developing application fields, which has important practical significance for the development of related application fields. Therefore, surface modification is one of the most important deep processing technologies for non-metallic minerals. Inorganic mineral fillers play an important role in polymer materials instry and composite materials field such as plastics, rubber and adhesives. These mineral fillers can not only rece the proction cost of materials, but also improve the rigidity, hardness, dimensional stability of materials, and give materials some special physical and chemical properties, such as corrosion resistance, flame retardancy and insulation. However, e to the poor compatibility between these inorganic mineral fillers and the matrix, it is difficult to disperse uniformly in the matrix. Direct or excessive filling often leads to the decline of some mechanical properties and embrittlement of materials. Therefore, it is necessary to modify the surface of inorganic minerals, enhance the compatibility between minerals and organic matrix, and improve the comprehensive properties of composites

In most cases, the change of mineral surface properties depends on the coating or coating of various organic or inorganic chemical substances (i.e. surface modifiers) on the surface of powder particles. Therefore, in a sense, surface modifier is the key of mineral surface modification technology. The surface properties of some minerals can be changed by simple acid-base treatment. Montmorillonite, such as calcium montmorillonite, attapulgite and zeolite, can be treated with inorganic acid (mainly sulfuric acid or hydrochloric acid), which can enhance the surface activity and improve the adsorption capacity

8. Because gear rection is compared to turbine rection. Suitable for high speed. So the gear is used first and then the turbine is used. It's like the rection of belts and gears. There must be a reason to use the belt first and then the gear. Hope to adopt
