• Ball mill/Rod mill unit

As the crusher model which is already in the SolidSim unit model library the ball mill model is based on Bond's law. For the ball mill the Bond Work Index is corrected by five efficiency factors considering the influence of open circuit milling, dry milling, the mill diameter, the inlet particle size and the size reduction ratio.

• Cone crusher unit

Based on the material size and the cone crusher settings a breakage probability is calculated. The fragment size distribution can be described using breakage functions according to Vogel or Austin. The combination od both results in a breakage matrix describing the size reduction of the inlet material.

• Jaw crusher unit

As for the cone crusher the breakage matrix describing the size reduction of the inlet material is calculated from the breakage probability and the breakage function. The breakage probability function here considers the machine settings of a jaw crusher while the same breakage functions can be used as for the cone crusher: Vogel or Austin.

• Impact mill unit

The impact mill model has been derived as generalization of the SolidSim Hammer Mill model. The impact velocity is not obtained from hammer mill specific machine settings butdefined by the user. Otherwise the same modeling approach is used. Using this model any milling due to impact can be described, e.g. a pin mill or jet mill.
