Rare earth powder sieving is an auxiliary process, but it not only determines the quality of the final commodity, but also has an important impact on product yield and environmental protection.Rotary vibrating sieve is an ideal choice to control the particle size of rare earth products.

Due to the long conveying time and many links in the conveying process, the crushing of bulk grain is unavoidable, and the crushing rate is as high as 35% in the conveying process in serious cases. Therefore, it is urgent for grain depot to solve this problem. The main reason for the higher grain crushing rate is that the structure design of trough chain conveyor is not reasonable enough in the conveying process. So it is necessary to strengthen the debugging and transformation of the grain conveying system, reduce the damage rate, avoid grain waste and improve economic benefits.

Along with the people to the value of sanitary conditions of grain feed stuffs, more and more people pay attention to the sanitary of food and feed processing equipment, which means in the process of each link of the discharge process, material requires no residue, no cross pollution, and the equipment requires simple mechanism and reliable operation. The new type of trough chain conveyor without material residue can realize material discharge without residue, avoid material cross contamination and material deterioration, and improve material quality.

As a new type of lifting product developed by introducing foreign advanced technology, chain bucket lifter is widely used in various industrial countries due to its features of energy saving, high efficiency, low noise and long service life. The chain bucket elevator is an inflow feeder, and the material flows into the hopper and is lifted to the top by the chain, and discharge by itself under the action of gravity of the material. Chain bucket elevator often has the phenomenon of chain plate falling off and cracking in the process of production.
