Converting a ball mill from overflow to grate discharge

Jun 23, 2020 One way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge. This can allow an operation to increase plant throughput or reduce the product size, which can each contribute to higher revenue, but there are several factors to consider before the decision to convert is made.

Ball mill

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.
