How to replace the grinding roller and grinding ring of Raymond mill?

Raymond mill is a commonly used grinding equipment, in which the grinding roller and grinding ring are the main core components. When the equipment is working, the grinding roller grinds the material under the action of centrifugal force.
During use, the grinding roller of Raymond mill is severely worn, but this wear is inevitable. So, how to replace the grinding roller and grinding ring of Raymond mill? Here are three tips.



1. The user needs to confirm the model of the replaced grinding roller and grinding ring. Only by using matching models can the working efficiency of Raymond mill be guaranteed and the wear degree of grinding roller and grinding ring can be reduced.
The grinding ring of Raymond mill is conical, which is generally hammered out by hammering from above. However, since there is not enough space in the grinding chamber of the equipment to complete it, it is necessary to use gas cutting to divide the grinding ring into several sections, so that the waste grinding ring can be easily removed.

2. When installing the grinding ring, it is necessary to clean up the internal waste residue to ensure that there is no residue on the inner wall of the air duct. When replacing the roller of the Raymond mill, it is impossible to use the gas cutting method, so a hammer is used to beat from bottom to top during replacement.
Some equipment has poor sealing between the roller and the roller shaft, which leads to dust entering, causing the roller and the roller shaft to rust. When it happens, you can use oxygen to bake for five minutes or drip engine oil into the gap and soak for half an hour, so that it is easy to disassemble.

3. When installing a new roller, the user needs to do a good job of cleaning to ensure that there is no residue on the roller shaft, and the sealing work needs to be done after installation to ensure the normal operation of the Raymond mill.



In short, the Raymond mill is a grinding equipment with a wide range of applications and high frequency of use. If it is used improperly, it is easy to cause failure.
Therefore, develop good usage habits in daily use, and check and maintain them frequently, to prevent problems before they happen.
