approach to high temperature of cement ball mill

In the operation of cement ball mill, the stop can cause a large temperature difference on the mill body, resulting in significant thermal stress and thermal deformation, and sometimes even cause mechanical damage of the ball mill, such as the geometric deformation of the liner. Starting the thermal deformation after the stop grinding can produce a certain penetration force, to form the current ripple and its own …
