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.

The belt bucket elevator has fast powder conveying speed, so the sealing problem of the lower section of the traditional is difficult to solve. This paper analyzes the problem existing in traditional structural sealing, and proposes a new type of sealing structure for the lower section of the belt bucket elevator, which solves the sealing problems of the lower section.

Corrugated sidewall belt conveyor can realize belt conveyance with a large inclination angle of zero to ninety degree and can transport various dry materials without relying on the internal friction angle of materials. However, many problems have been exposed in the process of use, which need to be reformed.

This paper describes the background, contents, and main features of the heavy-duty apron feeders.

vibratory separator is a high precision fine powder screening machine with low noise and high efficiency. It is suitable for the screening and filtration of granule, powder, mucus and other materials. In the existing technology, the rotating vibrating screen will be blocked by particles after a long time of work, and the screen’s holes will be blocked. When the phenomenon of hole blockage occurs, the whole machine should be disassembled and cleaned, which is inconvenient to operate and inefficient. The purpose of this paper is to provide an anti-blocking rotating vibrating screen with high scr
