broyeurs à boulets
Ball mills have a diameter of up to 6 m and a capacity of up to 400 t/h, and consume 12-16 kW.h/t. Roller mills are designed to process up to 400 t/h and require less energy, in the region of 10-14 kW.h/t., since they work at higher pressure, and need feeding with a relatively lower water content.
