1. Classification of mining machinery
crushing equipment
crushing equipment is the mechanical equipment used to crush minerals
crushing operations are usually divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging particles. The commonly used sand and stone equipment include jaw crusher, impact crusher, impact crusher, compound crusher, single stage hammer crusher, vertical crusher, rotary crusher, cone crusher, roller crusher, double roller crusher, two in one crusher, one-time molding crusher, etc
it can be divided into six categories according to crushing mode and mechanical structure characteristics (action principle)
(1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block sandwiched in it< (2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block
(3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher
(5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6) other types of crushers and grinders
mining machinery
mining machinery is the mechanical equipment used for directly mining useful minerals and mining preparation, including: mining machinery for mining metal ores and non-metal ores; Coal mining machinery for mining coal; Oil drilling and proction machinery for oil proction. The first pneumatic disc shearer was designed by the British engineer Walker and manufactured in 1868. In the 1880s, hundreds of oil wells in the United States were successfully drilled by steam powered percussion drilling. In 1907, the roller drill was used to drill oil wells and natural gas wells. Since 1937, it has been used to drill open-pit mines< Mining machinery
the mining machinery used in underground and open-pit mines include: drilling machinery for drilling blastholes; Mining machinery and loading and unloading machinery for mining and loading rocks; Boring machine for drilling raise, shaft and drift< Drilling machinery can be divided into rock drill and drilling machine, and drilling machine can be divided into open-pit drilling machine and underground drilling machine

8. Mining is the technology and science of mining mineral resources from the earth's crust and surface. Mining in a broad sense also includes the exploitation of coal and oil. Mining instry is an important raw material instry, metal ore is the main raw material of smelting instry, non-metal ore is an important chemical raw material and building materials
development and mining process
the ore deposit development steps are shown in the figure. The mining of ore deposit includes two major projects: infrastructure development project and proction mining project. A series of roadways or gullies should be excavated to reach the ore body in underground mine development, and a complete mining proction system should be built and put into proction. There are two kinds of mining proction process:

main proction process

Mining
including: ① mining preparation, cutting, preparing proction conditions for mining. ② The ore is broken and loaded into transport containers. Underground mining includes ore caving and ore drawing (see underground mining method); Open pit mining includes perforation, blasting and mining and loading operations (see open pit mining method). ③ Transport, transport the ore loaded into transport containers to the concentrator or bin (see mine lifting, mine transport, open pit transport). ④ Manage roadway pressure, shaft pressure, stope pressure and open pit slope. ⑤ In the process of ore transportation, ore is mixed evenly through ore bin and stack to ensure the stable quality of ore. ⑥ The waste rock proced by roadway excavation and stripping is discharged to the waste rock yard
e to the different geological and technical conditions of the deposit, there are many kinds of mining methods. Different mining methods have different mining process, mining machinery and equipment, roadway layout and mining sequence. Improper selection of mining methods will affect the technical indexes and economic benefits of mine proction for a long time. In order to obtain the best economic effect, the appropriate mechanical equipment must be selected for each main proction process.

mining equipment
tunneling includes roadheader / gangue raker / belt conveyor / transfer / crusher, and mining equipment includes shearer, drum shearer, plough, bending scraper conveyor, self moving hydraulic support, bridge conveyor and telescopic belt conveyor / hydraulic support / scraper conveyor, etc.
including mining machinery for mining metal ore and non-metal ore; The oil drilling and proction machinery used for oil exploitation, such as drum shearer, plough, bending scraper conveyor, self moving hydraulic support, bridge type transfer machine and telescopic belt conveyor, can be divided into crushing machinery (adjustable fine crushing machine, jaw type crusher, box type crusher, impact crusher, etc.), grinding machinery, screening machinery and so on Separation (separation) machinery and dehydration machinery, as well as a variety of proction lines. According to the principle of action, the separation machine is divided into gravity separation machine, magnetic separator, flotation machine and special separation machine. Mineral processing machinery is also used in building materials, chemical instry, glass, ceramics and other instrial sectors. Mineral processing is the process of selecting useful minerals from the collected mineral raw materials according to the differences of physical properties, physicochemical properties and chemical properties of various minerals. The machinery that implements this process is called beneficiation machinery. According to the beneficiation process, beneficiation machinery is divided into crushing, grinding, screening, separation (separation) and dehydration machinery
jaw crusher, rotary crusher, cone crusher, roller crusher and impact crusher are commonly used in crushing machinery; Cylinder mill is the most widely used in grinding machinery, including rod mill, ball mill, gravel mill and autogenous mill; Inertia vibrating screen and resonance screen are commonly used in screening machinery; Hydraulic classifier and mechanical classifier are widely used in wet classification. According to the function principle, the separation machinery is divided into gravity separation machinery, magnetic separator, flotation machine and special separation machinery. The earliest separation machinery was gravity separation machinery. The first piston jig appeared in Germany from 1830 to 1840, which was used for metal ore separation; The first magnetic separator (belt type low intensity magnetic separator) came out in 1888; The first mechanical stirring flotation machine appeared in 1910. Gravity mineral processing machinery is a kind of equipment that uses the difference of density and particle size between ore particles and gangue to separate in moving medium, including jig, heavy medium concentrator and centrifugal concentrator. Jigging machine makes water flow in water tank by means of diaphragm, piston or compressed air, so that the ore particles on the screen are stratified according to density and particle size under the action of pulsating water flow. The ore particles with high density pass through the bed rock layer on the screen and gather at the bottom of the water tank to become concentrate, which is discharged from the discharge port. Trapezoidal jigs, double chamber movable cone bottom jigs and compound vibration jigs are mainly used to separate metal ores; There are side drum jig and under screen air chamber jig for coal preparation. Dense medium concentrator uses suspension or heavy liquid as dense medium to separate ore particles from gangue. There are mainly heavy medium vibration chute, heavy medium swirler, inclined wheel heavy medium coal separator and vertical wheel heavy medium coal separator. Centrifugal concentrator is a machine used to recover metal particles in fine slime, which is mainly composed of host and control mechanism. In the centrifugal force field proced by the high-speed rotation of the cone drum of the main engine, the heavy ore particles deposit on the drum wall and become the concentrate, while the light ore particles attach to the surface of the concentrate and are discharged from the drum and become the tailings under the action of the flow film (pulp flow). The magnetic separator is a kind of machine which uses the magnetic difference of various minerals to separate minerals with the help of magnetic force and mechanical force. The magnetic separator is composed of magnetic system, separation device, feeding and discharging device. There are many kinds of magnetic separators, such as permanent magnet cylinder magnetic separator, electromagnetic flat ring high intensity magnetic separator and high gradient high intensity magnetic separator. Flotation machine is a kind of machine which uses the difference of physical and chemical properties of particle surface to separate fine minerals. The flotation agent is attached to the flotation machine. By means of compressed air or mechanical stirring, the ore particles that are not easy to be wetted by water are attached to the bubbles (positive flotation method), raised to the liquid level, and discharged as concentrate through the discharge device. The ore particles that are easy to be wetted by water are left in the tank and discharged as tailings. The concentrate from wet beneficiation needs to be dehydrated to separate the solid and liquid. Dehydration machinery can be divided into thickener, filter, centrifugal dehydrator and dryer
exploration equipment
mainly includes rotary drilling rig, rotary vertical shaft drilling rig, derrick (drill tower), winch, power engine (motor, diesel engine), mud pump and other equipment, as well as manipulator and pipe twisting machine and other ancillary equipment< With the development of social economy and the acceleration of commodity circulation, the competition among similar commodities in the same instry is becoming more and more fierce. Enterprises often compete for the target customers not only in quality, but also in technology, style and brand. The brand competition is the key for an enterprise to occupy the market quickly and obtain a large number of target customers< Mining machinery instry status
mining machinery is specialized in the proction of a variety of mining machinery and ore refining machinery instry, however, e to economic development and increased demand for consumption and considerable profits, many enterprises swarmed into the instry. However, the increase of enterprises is that the target customer market is scattered, and the profit margin is greatly reced, which makes manufacturers often imitate proction according to the original mechanical equipment in the market, rather than innovate technology and enhance the content of science and technology. The emergence of a new proct in the market will soon be imitated and copied, and the influx of foreign procts and competitive pressure
disordered competition in the domestic market, slow proct update speed and long technology upgrading cycle are the key factors restricting the development of mining machinery instry. How to make this instry rapidly improve proct value and technology content, so as to drive the development of the whole instry and cope with the competitive pressure of foreign manufacturers. It is the primary problem faced by domestic mining machinery instry
establish brand awareness: the so-called brand awareness refers to an enterprise's basic concept of brand and brand building, which is a comprehensive reflection of an enterprise's brand values, brand resources, brand equity, brand competition, brand development, brand strategy and brand building. It can be said that brand awareness provides a solid rational foundation for enterprises to formulate brand strategy and build a strong brand, which has become a strategic awareness leading enterprises to win in modern competitive economy
establish the sense of innovation: an enterprise can only have a career if it tries. Enterprise and innovation, and breakthrough. Enterprises should change from pursuing profit maximization to pursuing sustainable growth, constantly innovate technology and improve the content of science and technology
establish patent awareness: for the research and practice of enterprise intellectual property strategy, enterprise patent strategy is the source field and relatively mature component. Patent, as an important part of intellectual property, plays a vital role in the development of enterprises. To establish and improve patent strategy is a necessary means for enterprises to enhance their core competitiveness in the domestic and foreign market competition. Enterprises must grasp the national conditions, grasp the rules, avoid risks, and master the self-defense and winning way of patent protection as soon as possible
government support: actively grasp and respond to the government's new policies and support policies for the instry. The development of enterprises is the key to vitalize and drive the development and strength of the nation< In 2008, the Ministry of land and resources issued the "guidance on promoting deep prospecting work" to promote China's solid mineral exploration to the deep. This shows that mining machinery and equipment stocks will face a new round of instry demand, especially drilling, field prospecting and many other equipment. More and more mines begin to use mechanized operation to improve mining rate and eliminate potential safety hazards. In coal, copper, zinc and other mines, the degree of mechanization has been greatly improved, which greatly enhances the market capacity of mining machinery and equipment
with the support of computer technology, network technology and other multidisciplinary integration, mining machinery is facing economic construction, driven by market demand, and in the harmonious development of human and nature, mining machinery has developed towards digitization, intelligence, ecology and amenity< The 21st century is an era of rapid development of science and technology and information. Emerging instries are constantly emerging and market competition is becoming more and more fierce. E-commerce, a new instry, is developing rapidly and driving the transformation of traditional instries. It is all walks of life that see new vitality and new direction. Especially at the time of the financial crisis, online retail B2B and vertical segment B2C have achieved a new round of rapid development, many B2C service providers have obtained a considerable number of venture capital, and traditional manufacturers have also tried the water, so B2C has achieved unprecedented development and prosperity
mining machinery manufacturers how to use e-commerce to drive enterprises to develop and grow faster and bring more profit space to enterprises has become a concern of the mining machinery instry. The previous sales mode of mining machinery engaged in crushers and mineral processing equipment is to seek agents and distributors, through which to promote the sales and development of enterprise procts, But the traditional business model has not been able to adapt to the development of small and medium-sized mining machinery, the increasing number of small and medium-sized manufacturers, the saturation of the market, the increasing competition of enterprises, the lack of market sales personnel and the shortage of funds have become obstacles to the development and progress of enterprises
the sustainable development of e-commerce in China is that these small and medium-sized manufacturers have seen a new sales mode network marketing. The difference between network marketing and traditional marketing lies in that network marketing is a marketing activity with Internet as the main means to achieve a certain marketing purpose. That is, in order to achieve the overall business objectives of the enterprise, the Internet is the basic means to create a variety of online business environment activities. And the traditional marketing is to use sales personnel to do marketing business and sales activities. How to carry out network marketing:
using websites to carry out network marketing activities
10. Gear recer instry is still developing rapidly in 2008 as a whole. Although the new orders decreased in the second half of the year e to the impact of the global economic crisis, the annual growth rate is still about 30% compared with the previous year, and the sales volume of the whole instry is expected to reach 50 billion yuan
in the first half of 2008, the proction tasks of enterprises in the instry were full, and the procts were in short supply. However, in the second half of the year, e to the impact of the global economic crisis on China's real economy, the demand of iron and steel, nonferrous metals, shipbuilding, mining, petrochemical, engineering machinery, light instry and lifting and transportation instries all dropped sharply. As a result, the orders of all proction enterprises decreased to varying degrees. However, this situation did not have much impact on the proction in 2008, It may have a certain impact on the next year's proction
the instry with strong demand in 2008 is wind power generation instry, followed by coal and building materials instry. The rapid development momentum of wind power instry has not been reced, so the demand of wind power gearbox, yaw and pitch planetary gearbox is still growing rapidly. Nanjing High Precision Gear Co., Ltd., Chongqing gearbox Co., Ltd., Dalian Crane Co., Ltd; The proction of this kind of procts of Heavy Instry Group Co., Ltd. has realized the mass proction, directly riding on the fast train of domestic wind power instry development, and the enterprise scale has also expanded rapidly. Affected by this, many enterprises have quietly acted or are eager to try. It is expected that in a few years, there will be more than ten large-scale wind power gearbox manufacturers in China. In addition, foreign famous wind power gearbox manufacturers such as Winergy and Hansen have also started to build factories in China. After a few years, the competition in the domestic wind power gearbox instry will become increasingly fierce
the cement, brick and tile instries in the coal and building materials instries are not obviously affected in this crisis, so their demand is still on the rise. With the increasing intensity of China's economic stimulus measures, it is expected that this trend can still be maintained
2. Proct technology status and existing problems
at present, the widely used recers in China can be roughly divided into five categories: gear recers, planetary gear recers, worm recers, cycloidal gear recers and all kinds of hybrid transmission boxes. In addition, there are some other types of recers, but the application is not very common
gear recer is a kind of recer with the largest number of applications. It includes cylindrical gear recer, bevel gear recer and bevel cylindrical gear recer. With the increase of domestic proction and market expansion of Flender, sew and other companies, many types of cylindrical gear recer have been applied in China, such as sew's R, F, F, etc. for medium and small power K series recer, in addition to large and medium power deployable cylindrical gear recer and special cylindrical gear recer for extruder and mixer. The above types of procts are not only proced by foreign companies directly in China, but also by nearly 100 domestic manufacturers. Except for some domestic standard zdy, ZLY, ZSY, DBY and DCY series procts and non-standard procts, most of the other manufacturers are imitation foreign series procts. It is an indisputable fact that the proct system of this kind of procts in the instry has been basically dominated by foreign companies, which is obviously not concive to the growth of domestic recer enterprises and the development of the instry, and is very easy to cause proct property rights disputes. A proct series system with molar design technology and independent intellectual property rights needs to be established, but e to various factors and constraints, Despite the appeals and efforts of many domestic institutions for many years, the progress has not been ideal, and the prospect is still unclear
planetary gear recer is another kind of transmission proct which is widely used in the market at present. Due to a series of advantages of planetary gear transmission technology itself, and the rapid development of China's instry in recent years, these have effectively promoted the rapid development and application of planetary gear transmission technology in China, All kinds of planetary gear transmission technology and corresponding procts have been developed and applied. Proct varieties and specifications are graally enriched. The maximum transmission load of procts has reached an unprecedented level, and the technical performance of procts has basically reached the advanced level of foreign similar procts. With the improvement of equipment conditions of relevant domestic manufacturing enterprises, many enterprises have joined the ranks of planetary gear box manufacturers in recent years. At present, the typical domestic R & D, design and manufacturing units of planetary gear transmission procts are: China Heavy Machinery Research Institute Co., Ltd., Nanjing high precision gear group Co., Ltd., Chongqing gear box Co., Ltd., Luoyang Zhongzhong gear box Co., Ltd Jingzhou giant whale Transmission Machinery Co., Ltd., Dalian Crane Group Co., Ltd., the second heavy machinery group company, etc
the main types of planetary gear recers proced in China and their characteristics are shown in the table below
Table 1 Types and characteristics of planetary gear recer
serial number name standard / series description characteristics
1 planetary gear recer JB / t6502-1993
JB / t9043.1-1999
JB / t9043.2-1999
JB / t6120-1992
JB / t7681-1995 general procts There are many proction plants, but they need to be updated urgently
2 series procts of planetary gear recer are used for vehicle walking or winch rotary drive
3 series procts of planetary gear recer are used for rotary drive of construction machinery, lifting machinery and wind power generation
4 star gear recer JB / t8712-1998 adopts hybrid small tooth difference transmission and is suitable for large speed ratio
5 two ring Three ring recer Yb / t079-1995
JB / t10299-2001 adopts less tooth difference transmission and is suitable for large speed ratio

one of the main problems of the planetary gear recer mentioned above is that the standard is relatively old, and the proct series and specifications are quite different from those of foreign countries, For example, planetary gear box series used in roller press and walking and rotary gear box series used in vehicle and construction machinery instry, but the problem of instry series procts to be upgraded is still very prominent, which should also be one of the problems to be solved< In recent years, the application field of planetary gear box has been expanding, and the typical application instries can be listed as follows:
(1) main drive of cement mill, vertical mill, roller press, glass mixer, brick extruder and stacker reclaimer in building materials instry
(2) wind power gearbox and yaw, pitch planetary drive, coal mill main drive, hydropower gearbox, tidal power gearbox, shearer main drive, roadheader main drive and walking drive in energy instry
(3) main drive of rolling mill, roller recer, mine hoist and grinding machine in metallurgical and mining instry
(4) belt conveyor main drive, crane walking and hook drive, scraper conveyor main drive
(5) in forging and metal processing instry, the main drive of plate bending machine, walking and working drive of forging operator, and main drive of pelletizer or pelletizer
(6) walking and rotary transmission of bulldozers, excavators, rotary drilling rigs and other construction machinery in construction machinery instry
(7) main drives of extruders, fans and pumps, and special vehicles in petrochemical instry
the situation of worm gear recer is slightly better. At present, the main types of domestic worm gear recer are shown in Table 2< Table 2 worm gear recer and characteristics
serial number name standard / series description characteristics
1 circular arc cylindrical worm recer JB / t7935-1999 adopts ZC1 worm with good performance
2 plane enveloping hourglass worm recer GB / t16444-2008
JB / t9051-1999 adopts hourglass worm with good performance
3 cone enveloping cylindrical worm recer JB / t7936-1999 adopts ZK1 tooth profile, It is suitable for medium and small specifications

in addition to the above types, there are some other types of worm recer series on the market, but they are no longer listed because of limited use or small proction quantity
the molar update of worm gear recer has been completed, and its performance is close to that of foreign procts. We should continue to work on the proct types and update series, so as to timely launch a new generation of series procts. At present, the main domestic manufacturers of worm gear recer are Jiangsu Jinxiang recer Co., Ltd., Jiepai Holding Group Co., Ltd., Star Technology Holding Group Co., Ltd., machinery plant of Beijing Shougang electromechanical Co., Ltd
cycloid pin gear recer is mainly used for medium and small power high speed ratio transmission. At present, the proct standard of domestic proction is JB / t2982-1994. Due to the large gap between the proct performance and that of foreign countries, after the cycloid fever in recent years, the number of cycloid pin gear recer manufacturers has sharply decreased, and many manufacturers have stopped procing such procts, We're turning to other types of procts. It is also an urgent choice for cycloid recer to improve and upgrade its performance as soon as possible
there are many types of hybrid transmission boxes, which are basically special series or non-standard procts, such as wind power and hydropower speed increase box, vertical mill main transmission gear box, large extruder gear box, etc. In recent years, with the rapid development of domestic economy, the development and manufacturing of hybrid gearbox have been developed rapidly, and the proct level is basically the same as that of foreign countries. It can be predicted that with the continuous development of technology in various instries, there is still a lot of space for the development and application of all kinds of hybrid transmission boxes, and it will be further developed.
