### 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.

### Practical modern techniques for the design of

Synopsis. A number of modern techniques suitable for the design of crushing and grinding circuits are described. The methods are based on extensive use of mathematical models of crushers, mills and classifiers and are seen as alternatives to conventional comminution design methods based on Work Indexcalculations.
