aspect of grinding and comminution in ball mill

Mining comminution crusher, ball mill, and advanced

It’s not uncommon for a large mine to have independent planners looking after blasting, primary crusher throughput, secondary and ball mill grinding as well as the concentration plant. A single-minded focus by any of these groups to maximize throughput may come at the expense of other units, and ultimately at the expense of overall throughput.

Ball mill Wikipedia

Jul 24, 2004· 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.
