Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paintsBall 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

Ball Mills an overview | ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter ( Figure 811 ) The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
