Recently, large-scale mechanized mining of coal has realized large-scale centralized washing. Due to various constraints such as national environmental protection, safety and economic benefits, large-scale coal mines and supporting coal washing plants have become an inevitable trend of new projects.

The use of scraper conveyor in China began in the 1960s, and the equipment has mature experience in the application of chemical industry, cement, grain and so on. Although the power industry is also used earlier, but because of the fluidity and abrasive properties of slag and fly ash than other materials, the use effect is not good, so for many years has been the use of hydraulic slag, ash transport

As we all know, apron feeder is generally divided into heavy, medium and light three kinds, is commonly used in concentrator feeding equipment, widely used from storage bin to crushing, transportation and other machinery for uniform continuous feeding. apron feeder includes auxiliary hopper, observation window, main hopper and feeding mechanism, feeding mechanism includes chain plate, hydraulic powertrain, drive shaft, drive gear, support wheel, chain

Sidewall belt conveyor is a special belt conveyor. Its main feature is that it can be transported vertically or at a large inclined angle. So what are the main advantages of it compared with the trough belt machine? The following will give you a detailed introduction to the differences and advantages of sidewall belt conveyor compared with ordinary belt machines:

Feeder breaker is a new type of equipment for comprehensive mechanized coal face in open-pit mine. In recent years, with the extensive exploitation of open pit mines in xinjiang, inner mongolia and gansu, new technical requirements have been put forward for the technical performance of equipment.

Belt conveyor cover has a fixed type, open type and observation window, you can see whether the material in the transmission process and the conveyor belt operation is normal, there is a deviation cover, for the conveyor with a deviation switch to play a role in rain, dust and so on.

Apron feeder is mainly used to transport all kinds of bulk or loose materials from storage to crusher, conveyor or other working machinery in a horizontal or inclined direction. Widely used in building materials, gold, mining and other industries, is an indispensable equipment in raw material treatment or continuous production process.

Mineral sizers are a kind of equipment that breaks materials by cutting, which has the advantages of large crushing ratio, good crushing effect, low powder formation rate and a wide range of materials.

Conveyor cover is a protective cover used in outdoor belt conveyor, its main function is to prevent wind, rain, snow and other damage and loss of belts and materials. Within a certain range, the greater the moisture content of coal, the greater the dust velocity of its particles, spray water dust removal is based on this mechanism to increase the external moisture of coal, increase the humidity of coal, so that the condensation effect occurs between coal particles. Relatively speaking, although this dust removal method is relatively simple in economy and management, there are also many proble

Banana screen structure is a kind of high-efficiency separation equipment, which is widely used in chemical industry, mining industry, grain industry and so on. In this paper, the structure of banana screen is optimized and its application in mining industry is introduced. By optimizing screen parameters and screen frame design, the screening efficiency and screening precision are improved. The application of banana screen can effectively separate the ore of different particle size and improve the production efficiency. In this paper, the advantages of banana screen in practical application ar

The apron feeder is powered by an electric motor in the transmission unit. After the reducer is decelerated, power is transferred to the drive shaft through the safety coupling. At this point, the two sprockets mounted on the drive shaft rotate with the shaft. In addition, the two chains engaged with the head-tail connecting wheels also move forward with the rotation of the drive sprocket and tail wheel. The chain plate is mounted on the chain and moves synchronously with the chain. The role of the chain plate is to bear the overall weight of the material. As the chain moves, the chain plate a

In recent years, with the expansion of mineral sizers in the coal, mining, construction, chemical and other fields, mineral sizers also break some wet or hard materials. As we all know, mineral sizers have two meshing tooth rollers. When hard objects such as non-crushing materials enter the crushing chamber, it will lead to overload operation of the motor or reducer, which will cause irreversible damage such as motor burning and reducer teeth beating. To this end, a mineral sizers speed measuring device is designed and developed. When the tooth roller encounters the hard object jam, the power

Scraper conveyor is one of the essential key equipment in the normal production and operation of coal preparation plant, which plays the role of transportation and batching. In view of the shortcomings of the screw in the tail tensioning device of scraper worm gear in coal preparation plant, such as easy rust, high maintenance cost, high labor intensity when the chain is tight or loose, the optimization scheme of hydraulic control of the tensioning device is proposed, and good results are obtained in practice.

Conveyor cover is installed on the belt conveyor to transport goods, environmental protection plays a very important role, when the goods in the transport link can reduce the loss and waste of goods, so that the conveyor belt in the transport link is relatively stable, in addition to increase the service life of transport equipment. Then what should you pay attention to in the application of this product? Let's find out more about it.

Apron feeder is the equipment to transport materials, because its driven shaft bearing shingle is not equipped with lubrication system, resulting in two months of use of the bushing strain phenomenon, resulting in the feeder shutdown accident.

Chute is the main component of scraper conveyor. Under the same processing technology and material, wear-resistant treatment of chute can greatly improve its service life and significantly increase the economic benefits of enterprises.

Apron feeder is a feeder for large pieces of material. Such as coal, ore, gravel, etc. Because of its unique impact resistance, it is widely used in all walks of life. The following are the problems encountered by our Xinjiang cement clinker customers in the process of use and the speed adjustment measures we have made in response to the problem:

Mine scraper conveyor is a common mine conveyor, its main working principle is by scraper device to scrape the material from the conveyor feed end into the conveyor, and then through the chain system and motor drive, the material is transported to the discharge end.

At present, most of the screening and crushing equipment used at the front end of pulverized coal furnaces in coal-fired boiler power plants at home and abroad are mainly rolling screens and mineral sizers. The coal below 300mm goes into the rolling screen for screening, and the material below 30mm passes directly through the material under the screen and out of the skip without entering the mineral sizers. The screenings enter the mineral sizers to 30mm, and then enter the coal mill to grind into pulverized coal,

Apron feeder is a continuous transport machine widely used in mining, gold, building materials, port, coal and chemical industry and mining enterprises. It is mainly used for the continuous and uniform supply and transfer of various large weights and abrasive bulk materials from the storage bin or transfer funnel to the crusher, batching device or transportation equipment. It is one of the important and essential equipment in the ore and raw material processing and continuous production process.
