1. The Current Of The Main Engine Increases, The Temperature Of The Main Engine Increases, And The Current Of The Fan Decreases

Causes: 1) feeding speed is too fast; 2) The air duct is blocked by powder, and the pipe exhaust is not smooth.

Solutions: 1) reduce the amount of feed, 2) remove the dust accumulation at the air duct or open the residual air pipe valve, and control the temperature at the feed inlet below 6 ℃.

2. The Main Engine Of Vertical Roller Mill Starts Slowly

Causes: 1) insufficient power distribution; 2) The voltage is unstable.

Solutions: 1) check whether the motor is in line with the power of vertical roller mill, and replace the suitable motor power; 2) Check the power line and set the voltage stabilizing device.
