Stage 4: Finish Process

Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill

Grinding Mills and Their Types – IspatGuru

Apr 09, 2015Some mills are compartmentalized with each subsequent section having a smaller ball size. The material can pass through to the proceeding section, but the balls cannot. This ensures that the smaller particles are attacked by the smaller grinding media. Ball mill is a versatile grinding mill and has a wide range of applications.
