Barry Wills' Blog: Keys to Best Practice Comminution

In all cases, he considers that an understanding of the transfer size (T80) to the ball mill is critical to achieve best economics in a SAG mill grinding plant. T80 is important to operators because when SAG energy and Bond Ball Mill Work Index on SAG ground ore are measured, accurate prediction of future throughput in any SAG circuit is possible.

A study of comminution in a vertical stirred ball mill.

Using a 5 litre batch mill, an experimental programme was designed to study the comminution characteristics of the stirred mill. A factorial design was prepared with the following parameters, which influence grinding in the stirred ball mill: pulp density, pin tip velocity and ball density and size. The energy required for grinding the chromite

Comminution Wikipedia

For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used.
