When it comes to the crushing and grading of limestone, mineral sizers is undoubtedly a highly regarded crushing device. mineral sizers play an important role in the processing and production of limestone. Their unique working principle and advantages make them an indispensable and important

Apron feeder is a kind of mineral, coal and other feeding equipment, with good impact resistance and wear resistance, with large processing capacity, low maintenance advantages. Conveying materials are mainly limestone, sandstone and iron powder,

Coal roller screen is a kind of equipment specially used for raw coal screening, which has the advantages of large processing capacity, no vibration, low maintenance cost and low operating cost.

Apron feeder is widely used in mining, metallurgy, building materials and coal industries. The machine is mainly used under the silo and funnel with a certain bin pressure, to send a variety of large-capacity materials to a variety of crushing, screening or transportation equipment in a short distance, uniform and continuous.

We have analyzed more than 50 mineral sizers in domestic coal mines in recent years and found problems, although these crushers have achieved significant economic benefits. Crusher teeth are the main working parts of the crusher, but also the main wearing parts, its life length and work efficiency not only directly affect the life and efficiency of the crusher, but also closely related to the crushing power consumption, production capacity and the quality of the discharge particle size.

This paper mainly analyzes the causes of apron feeder bearing wear and common repair processes, and analyzes how online repair technology uses polymer metal repair materials to solve the wear repair of plate feeder bearing position on site. Its biggest advantage is that it can realize on-site repair, with high repair efficiency and less manpower and material resources. The service life after repair even exceeds that of new parts.

Our company provides two traditional coal roller screens to our customers. When the coal quality is good in the early stage of operation, the coal roller screen runs stably.

The power of apron feeder can be divided into three powers: no-load operation, conveying materials and lifting materials. The calculation formula and chart are introduced separately. The driving power of apron feeder for designing high temperature materials can be obtained by checking the chart and performing simple calculation. This power graph algorithm is fast and convenient.

For the brick making enterprises that need to pass the compost trommel screen, in the case of wet raw materials, the screen is easy to be blocked, which is a very tricky thing for brick making enterprises.

Mineral sizers are mainly used in the coal industry in the primary and secondary crushing of coal. One of the most obvious problems is that the updating and iteration speed of the crushing tooth material is slow, the crushing tooth material is single, and it cannot be applied to all application scenarios.

Sidewall belt conveyor comprises a driving device, a driving roller, a reversing roller, an upper supporting roller, a press pulley, a supporting roller, and a sidewall belt conveyor: The baffle conveyor belt includes a base belt, a baffle and a transverse baffle, and the baffle is corrugated, bonded or secondary vulcanized on both sides of the base band, and there is an empty edge between the baffle and the edge of the base band, and the transverse baffle is bonded or vulcanized on the base band between the two sides of the baffle at a certain distance, and the baffle on both sides and the tw

Apron feeder is generally divided into heavy, medium and light three, is commonly used in concentrator feeding equipment. 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 continuo

Mineral sizers is the main crushing equipment in the coal preparation industry, and is also widely used in solid waste treatment, construction waste separation and other fields. It has the characteristics of directly passing the material with the particle size meeting the requirements and forcing the crushing of large materials, which can achieve the dual purpose of crushing and screening of materials at the same time.

The copper ore of one of our customers has a large amount of mud. During the rainy season every year, a large amount of ore is bonded by mud. The vibrating screen in the process is often blocked by mud containing ore, resulting in the unimpeded discharge of ore.

The ore of the mining face falls to the heavy apron feeder through the chute and is transferred to the special conveying equipment of the mine. The heavy apron feeder is the key link between the mining and beneficiation system, and is the throat equipment in the mine production. The heavy apron feeder is installed in the lower part of the chute.

In recent years, semi-continuous mining technology has been widely used in large open-pit coal mines. In this mining process, mineral sizers are the key equipment.
