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.

Control of ball mill grinding circuit using model
Controlling the performance of a closed circuit ball mill is a challenging problem due to its complex dynamic characteristics and heavy interactions among the control loops. Traditionally, the grinding circuits are controlled by multiloop PID controllers which are heavily detuned to avoid multivariable interactions.
