The optimum mixture of a number of give components is calculated to achieve a desired particle size distribution. This is a typical task in the production of abrasives.

A process flow sheet can be set up to visualize the effect of an undustrial classifier.

A comminution process is desribed in terms of the particle concentration ration (pcr). The flow sheet, the characteristics of the mill, and the PSD data can be displayed in tables or diagrams.
