cascade and cataract in ball mill

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 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.

Ball Mills an overview ScienceDirect Topics

Following drum rotation, balls or bearings rise by rolling along the cylindrical wall and descending again in a cascade or aract from a certain height. The output is then milled between two grinding bodies. Ball mills could operate dry or even process a water suspension (almost always for ores). Dry, it is fed through a chute or a screw
