cause of cement mill bearing temprature rise

Starting the thermal deformation after the stop grinding can produce a certain penetration force, to form the current ripple and its own vibration in the operation; in addition, the heat of cement ball mill transforms to the main bearing can increase the temperature of main bearing. The grinding ability of material will reduce in accord with the increasing temperature
