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. Since the 1970s, many domestic coal mines have had to change the mining process due to the lack of such equipment, which has increased the mining cost.

One of our customers cement factory No. 3 limestone crusher selected BL type impact crusher for primary crushing, its feeding system adopted 1500× 12000apron feeder, the drive motor selected Y225M-4 three-phase AC asynchronous motor.

The calculation of mineral sizers productivity in China is mostly based on the structure and motion parameters of mineral sizers, without considering the effect of material properties on mineral sizers productivity. In this paper, a virtual prototyping method based on EDEM for mineral sizers productivity research is presented. Based on the material characteristics of mine users, various factors affecting mineral sizers productivity are analyzed and studied, which provides a reference for mineral sizers design and selection.

Steep angle conveyor is a new type of belt conveyor, which is mainly used in coal, chemical industry, electric power, metallurgy, light industry, building materials, port and bulk grain conveying industries. In the early 1960s, the equipment was first developed by a german company.

banana screen mainly has a concave screen surface. The Angle of the screen surface and the horizontal plane of the banana screen gradually decreases from the feeding end to the discharging end.

We used a belt feeder for one of our copper miners and recently installed an apron feeder to replace the belt feeder we used. We will be the whole process of manufacturing, installation and use of apron feeder, and measured some data on the site. The following is a brief introduction to the working conditions of the copper mine factory, the problems existing in the use of the original belt feeder and the design and use of apron feeder.

Mineral sizers, including the feed hopper, crushing system, base part and electrical control part, is characterized by the crushing system is composed of main and secondary drive motors, high and low speed tooth roller rotors, material guide, crushing, screening and discharging devices, wherein the high and low speed tooth roller rotors are located on the side of the feed hopper outlet.

Banana screen is mainly composed of spring, motor, box type vibrator, intermediate shaft, drive shaft, screen frame, screen beam, screen plate rail seat, polyurethane screen plate, etc. Banana screen is designed according to the principle of equal thickness screening, using continuous multi-angle screening surface, suitable for the type screening containing a large number of fine particles. The screen surface is composed of 6 sections with different inclination angles, the inclination angle of the screen surface at the feeding end is up to 25°, and the inclination angle of the screen surface a

The update of our heavy-duty apron feeder is essential due to the outdated technology used in the previous version. In comparison to similar equipment abroad, it has several shortcomings such as material surging, deviation issues, low efficiency, and high energy consumption. These drawbacks hinder its ability to meet the demands of the market economy. Consequently, we are compelled by objective factors to consider replacing this equipment.
