A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
is the specific rate of breakage, M is the mass of material in the mill, and m i is the fraction of the mill contents in size class i. The formulation of PBM for grinding has been developed by different authors (e.g., Austin et al., 1984). In brief, a mass balance for class …
