Ball Mill: Single chamber ball mills (with classifying liners and dam ring) with drying chamber and static or dynamic separator are commonly existing for coal grinding in cement plant for one or more kilns as per capacity. Ball mill is a cylinder rotating at about70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

ρ charge =total coal mass+ ball mass / J ∗Millvolume. α is the angle of repose, which is estimated to be about 35°. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more.
