Modelling and simulation of particle breakage in

2004-12-10  Impact breakage takes place at a much shorter time scale compared to the fragmentation process used in cone or jaw crushers. Hence, the nature and magnitude of forces as well as the energy transfer and dissipation related to impact breakage are very different from the relatively slow breakage by compression and shear used in other types of

Modelling and simulation of particle breakage in

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.
