The structure of the discharge grate plate system is similar to the double-layer partition plate system, except that the discharge grate plate has no blind plate and no flow control system.
The function of the discharge tube plate is to remove the material inside the mill in time, without affecting the material-to-ball ratio and material residence time in the attachment area of the discharge grate plate at the end of the mill. In this way, the grinding efficiency of the mill is guaranteed, the ventilation capacity inside the mill is improved, the internal temperature of the mill is reduced, and the fine powder can be taken away in time, which greatly improves the grinding effect of the mill. It has the functions of controlling the material flow rate, balancing the grinding capacity of the head and tail bins, increasing the material-to-ball ratio and preventing reverse classification, thereby increasing the effective use of grinding kinetic energy and increasing the output.
Solve the problem of blockage of the whole discharge plate
1. Regularly clean the whole plate grate
2. Use a grinding body with better quality. Since the ground cold in the grate plate is mainly broken grinding break, small grinding body and difficult-to-grind related granular materials, etc., the new horse brand grinding body is not easy to wear and break. .
3. Regularly clean the grinding bodies in the grinding chamber, and remove the small and broken grinding bodies
4. Professional technical engineers composed of technical talents of Hefei Cement Research Institute can optimize the design of the discharge grate according to the mill structure and material conditions, and minimize the problem of grate blockage.
