The utility model discloses an easily replaceable anti-wear device for a banana screen lower crossbeam, in which an easily replaceable wear-resistant protective top is arranged between the screen plate and the lower crossbeam, and under the protection of the wear-resistant protective top, the lower crossbeam is not worn.

In view of the low efficiency and high labor intensity of replacing the traditional heavy duty apron feeder chain plate devices one by one, we adopted measures such as setting up slipway platform to improve the maintenance site, pre-assembling the chain rail and chain plate in non-maintenance time, and carried out the overall replacement, which significantly improved the replacement efficiency, reduced the labor intensity of employees, and reduced the downtime of the sintering machine by more than half. The output of sintering machine is increased.

Vibrating screen is the key equipment in industrial production, processing in line with the process requirements of banana screen screen, for industrial and mining enterprises economic and reasonable operation, optimize production costs, reduce the labor intensity of workers has far-reaching significance. SUS304 stainless steel is widely used in various industries due to its high surface gloss and good corrosion resistance. Under special working environment, the screen plate must be processed using SUS304 stainless steel sheet.

Apron feeder is widely used in mining, metallurgy, building materials and coal and other industrial sectors, suitable for short distance transport of large block degree of materials, with the advantages of large load bearing, uniform ore feeding, strong impact resistance. At the same time, it also has the disadvantages of large volume, more moving parts, more lubrication points, and large maintenance workload.

In order to solve the drawbacks of traditional mineral sizers using safety pin as overload protection, such as easy to break pin, difficult to replace, long maintenance time and high cost, the traditional safety pin overload protection mode is reformed by using the principle of dental insert safety clutch. The results show that the clutch can reset automatically after the overload fault is eliminated, the operation is reliable, the maintenance is simple and fast, the cost is low, the service life is long, and the direct and indirect economic benefits are significant.

The initial construction scale of Xinjiang opencast coal mine was 1.5 million t/a, and after being put into operation, the scale gradually reached 7 million T /a after repeated renovation. At present, the mine adopts semi-continuous mining technology, which is mainly composed of fixed crushing station under pit, 1" screening workshop, final coal loading bin, 3# and 4 screening crushing system, coal storage facilities, off-site road and living facilities.

There are three series designed by an iron concentrator, among which series I and II are oxidized ore series and series III are primary ore series. In 2018, in order to further improve the grinding grade and processing capacity of series Ⅲ primary ore

The crusher of our customers in Xinjiang is designed and produced by our company, with the designed crushing capacity of 3000t/h. The crusher, together with the belt conveyor, type A and Type B cars, forms the semi-continuous production system of Yimin open-pit mine.

With the newly building of large coal mine and coal preparation plant in our country, the capacity of mineral sizers has not been met. Therefore, on the basis of absorbing and drawing on the advantages of the existing crusher at home and abroad, I have developed the large medium crusher mineral sizers high strength double-tooth roller mineral sizers.

Sidewall belt conveyors often provide significant benefits for higher capacity conveying due to lower power requirements, less wear and minimal spillage. Sidewall belt conveyors are more suitable for wood chip transportation.

Feeder breakers offer a robust, high-capacity and reliable solution for primary coal crushing at mine sites. Their ability to control product size, limit fines and operate continuously with minimal maintenance contributes to improved mine productivity, safety and reduced operating costs.

Apron feeder is a kind of continuous feeding machinery, which is suitable for conveying various blocky, granular or powdery materials, such as ore, coal, cement, building materials, etc. The plate feeder is composed of motor, reducer, sprocket, chain, chain plate and conveyor trough, which can realize uniform and continuous feeding of materials.

For a long time, people have been crushing materials by extrusion, i.e., by applying pressure to the material to deform it. When the energy absorbed by this deformation is sufficient to overcome the bonding force between the atoms of the material, the displacement between the atoms is produced, thus achieving the purpose of crushing the material. On this basis, crushing equipment such as jaw crushers, rotary crushers, impact crushers and hammer crushers have been developed.

This paper introduces the general situation of mineral sizers crusher and its profile and layout design. The shape of the roller teeth and the structure of the roller teeth layout in the crushing box were designed. Adopt an efficient roller tooth shape and crushing anvil

On the basis of the traditional crusher, a new type of mineral sizer is developed, the working mechanism, structure and technical characteristics of the crusher are introduced, and the three-dimensional software Pro/E is used for three-dimensional modeling and motion simulation. Through the simulation of the mechanism, the design of the product is optimized, the development cycle of the product is shortened, and the reliability of the product is improved.

Mineral sizers crusher is widely used in the waste rock and ore crushing in open-pit coal mines. It is the key equipment of semi-continuous mining process in the crushing field of large open-pit mine. It has the characteristics of short process flow, high crushing efficiency, little damage to the environment, and can reduce the transportation cost of ore.

Details and application of mineral sizers At present, the commonly used mineral sizers module particle size has roughly the following two adjustment modes: 1) Adopt eccentric ring to adjust the roller spacing, the adjustment range is less than 40mm. Advantages: The adjustment is simple and the workload is small. Disadvantages: the center distance and center height of crushing roller will be changed after adjustment. Therefore, the transmission part needs to be adjusted greatly. The adjustment mode is mainly used for through crusher.

When mineral sizers are used in the open pits in the cold area, it is common to see the broken material sticking to the roller, especially in winter. The material makes the rollers sticky, the tooth tip can not be exposed, so that the tooth roller can not complete the hammer operation, becoming the smooth roller, the material can not be broken. So that the upper conveying mechanism material accumulation, it can only stop for cleaning. Cleaning labor is intensity and waste time, greatly affect the work efficiency. The phenomenon of parking cleaning should be carried out several times a day, so

Taking the raw coal screening system of a coal preparation plant in Shanxi Province as the engineering background, the working principle of flip flow screen and banana screen selected in the system were expounded, and the screening effects of the two screening devices were compared under the same conditions.  The results show that, under the same conditions, the flip flow screen has higher processing capacity and better screening rate, and the overall screening process performance of flip flow screen is higher than that of banana screen.  Therefore, the coal preparation plant should give prior
