Such common failures are described in the detailed technical description of Raymond mill. In addition, the fault problem cannot be handled at will. The technician should be consulted or the technician should be informed of the troubleshooting. In addition, the whole process of troubleshooting should be carried out under the condition of power failure to avoid other accidents.

Predictive maintenance, which is similar to preventive maintenance but fundamentally different, prevention is the prevention of all possible problems, but the essence does not necessarily occur, and anticipation is the anticipation of what is about to happen, which has been predicted to varying degrees, but has not caused serious consequences. 

Based on the information provided by the status monitoring and diagnosis technology, necessary and appropriate maintenance can be carried out before the failure occurs. Most skilled operators can detect potential faults in advance through sound and finished products, so as to prevent and cure them early.
