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 …

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

10%During ball milling, up to 80 % of the energy that is generated in the mill is dissipated as heat [ 5 ]. This is why measurement and control of the temperature in the ball mills is important, for example, if heat-sensitive products are formed that would be degraded, or side reactions that would be favored at high temperatures [ 6, 7 ].
