Raymond mill maintenance

 DOWNLOAD

1. During the use of Raymond mill, there should be fixed personnel to take care of it, and the operators should have a certain level of technology. Before the installation of the mill, necessary technical training shall be conducted for the operators to make them understand the principle and performance of Raymond mill and be familiar with the operating procedures.
2. In order to ensure the normal operation of Raymond mill, the equipment maintenance safety operation system shall be formulated to ensure the long-term safe operation of the mill, and necessary maintenance tools, lubricating grease and corresponding accessories shall be provided.
3. After the Raymond mill has been used for a period of time, it should be overhauled. At the same time, vulnerable parts such as the grinding roller, grinding ring and blade should be overhauled and replaced. The connecting bolts and nuts of the grinding roller device should be carefully inspected before and after use to see whether there is looseness and whether the lubricating grease is sufficient.
4. When the roller device of Raymond mill is used for more than 500 hours, when the roller is replaced again, the rolling bearings in the roller sleeve need to be cleaned, and the damaged parts should be replaced in time. The refueling tools can be manual refueling pumps and grease guns.
5. Fineness adjustment: according to the size, softness, hardness, moisture content and specific gravity of materials, the processing thickness is also different. The analyzer above can be adjusted to have high rotation speed, high fineness, low rotation speed and low fineness. If the fineness is increased, the output will be reduced accordingly. If it still fails to meet the requirements, the fan speed should be adjusted, and the user can flexibly master it.
6. The scrapping limit of the roller and ring of Raymond Mill shall not be less than 10mm for the remaining small wall thickness.
7. When the Raymond Mill stops, stop feeding first, and the main machine continues to grind the residual abrasive. After about one minute, turn off the main machine motor and analyzer motor to stop the grinding work, and then stop the fan motor to blow away the residual powder.
