### Cement Grinding Optimisation - ScienceDirect

due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. cement grinding using stirred mills (pilevneli and azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. for specialized types of cement, which are finer than portland, this figure would be even higher.

### Cement Mill - Wikipedia

a ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. material fed through the mill is crushed by impact and ground by attrition between the balls. the grinding media are usually made of high-chromium steel. the smaller grades are occasionally cylindrical ('pebs') rather than spherical.

### Cement Grinding In Ball Mills And Vortex Layer Devices

grinding cement in ball mills. the principle of the ball mill operation is simple: it consists of a rotating drum and grinding media (cylinders, balls etc). the material is placed into the drum which starts rotating. the grinding media and the substance both come in circular motion and at a certain point drop from the walls the bottom of the drum.
