Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50100mm steel balls are used in the coarse grinding chamber, φ2050mm steel balls are used in the fine grinding chamber. 2.
