Summary：In general, the inlet and outlet of raymond mill will have a tight seal, and the gap between the joints of each pipe bearing will cause the equipment to enter the air during operation. When working, there will be a phenomenon of powder leakage.

Reasons for leakage of powder in Raymond mill and preventive measures
 
1. In general, the inlet and outlet of raymond mill will have a tight seal, and the gap between the joints of each pipe bearing will cause the equipment to enter the air during operation. When working, there will be a phenomenon of powder leakage. At this time, I have to solve these gaps and the problem of poor sealing in time to avoid the phenomenon of powder leakage.
 
2. Under the action of heat and water vapor, it will cause the system to expand in volume, thereby increasing the overall wind pressure of the equipment and greatly reducing the output and quality of the Raymond machine. If the equipment itself is not tightly sealed, the powder processed during operation will leak powder, which not only wastes the raw materials to a certain extent, but also affects the surrounding environment and air.
 
3. To avoid the phenomenon of leakage of powder must start from reducing the wind pressure on the equipment when running. At this time, the exhaust fan can be connected in series on the residual air duct of the equipment, thereby achieving the purpose of reducing the wind pressure. When installing the exhaust fan, pay attention to the position of the residual air duct, which should be on the air duct near the blower, so as to avoid the material being sucked in by the residual air duct.
 
Strictly perfecting the structure of Raymond mill can avoid the phenomenon of powder leakage, improve the production efficiency of Raymond mill, and improve the quality of processed products and save raw materials. It can also reduce the environmental damage caused by dust being discharged into the air.
