Ball Mill Outlet Cement Tempreture

Through the injection of water into the ball mill, excess heat is dissipated and the outlet temperature is kept at the desired level. Only if overtemperatures can be reliably avoided, the ground raw material or the ground cement can be safely and efficiently conveyed and stored.
