Cause analysis and solution of frequent burning of variable frequency motor

A company’s 2500t/d new dry clinker production line was put into operation in 2004, and the equipment operation has been relatively stable. However, in July 2014, the reducer of the raw meal mill and separator was mechanically damaged. After replacing the new reducer, the motor of the separator was burnt out several times in a row. Only after the motor of the powder separator is re-selected can the safe use effect be achieved.
