modeling and simulation of particle breakage in impact crusher

Modelling and simulation of particle breakage in impact ...

10/12/2004  In the model for impact crushers developed by Czoke and Racz (1998), it is assumed that the particles entering the crusher are subjected to a single-breakage process that results in the following mass balance equation: (2) p ― = B ― ― C ― ― f ― + (I ― ― − C ― ―) f ― The above equation corresponds to a scheme where the classification and breakage matrices are connected in series

Modelling and simulation of particle breakage in impact ...

The minimum size of the particles that undergo breakage is assumed to be a function of the impact energy and the feed rate. The model predictions are compared with experimental data obtained for limestone treated in a pilot-plant hammer crusher. The dependence of the product size distribution on the rotor velocity is investigated. The influence of the feed rate on the product size is also simulated.
