Solutions for pulverizer mill sieve block

There may be existing problems of the design of sieve plate in pulverizer mill ,and the sieve blocking is one of common faults in the pulverizer mill operation. The following are solutions for mill sieve block.

The feeding speed is too fast,increasing the load,causing the sieve blocking. In the feeding process, we should always pay attention to the deflect degree of ammeter indicator. If surpasses the rated current, the motor is overload, it will be burnt with long time overload.In this case, we should diminish or close the feeding gate immediately,or change the feeding way.

The broken hammer with large wear, the sieve hole is closed and broken. The pulverizer mill sieve will be blocked by milling materials with high moisture content.We should replace broken and badly worn hammer regularly, keep the grinder in good working condition and check the sieve regularly. The moisture content of milling material should be lower than 13％. Not only improve the productivity, but also make the grinder sieve won’t be blocked, enhance the reliability of the grinder operation.
