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.

Modelling and Control of Ball Mill Grinding

The mill feed (quartz in the range of 600-1700 um) is delivered by a PI-controlled belt conveyor accurate to ±1%. The water addition to the mill is automatically adjusted by a peristaltic pump to maintain a constant percentage of solids in the feed (65%). A PDP 11/23 mini-computer is used for remote set-points control.
