Before starting the vertical roller mill, it is necessary to check whether the connecting bolts of each part of the unit are tightened and whether the tightening degree of the transmission belt is appropriate; Check whether the power cord is good; Check whether the motor shaft is parallel to the mill shaft.

Check whether the hammer is good, whether the aperture of the screen is suitable and whether there is any damage. Drag the belt by hand to check whether the spindle rotates flexibly, whether there is a card or a friction phenomenon.

After starting, make the vertical mill idle for 2-3 minutes to check whether the rotor steering is correct and the sound is normal. It can work only if the rotation speed is stabilized at rated speed.

In the work, we should pay attention to the operation of the grinder at any time, so that the feeding should be uniform, so as to prevent clogging, and not to work over a long time. If there is any vibration, murmurs, excessive body temperature and sprayed material, stop and check immediately. After troubleshooting, you can continue to work.
