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

15.03.2013 A novel method to simultaneously simulate particle motion and its breakage in a dry impact pulverizer was developed. The motion of particles in the pulverizer was calculated using a discrete phase model (DPM)-computational fluid dynamics (CFD) coupling model. When the particle impacts against a vessel wall, impact stress acting on the particle is calculated

01.04.2015 DEM simulation using a breakage model is applied to study a broad range of existing impact based crushers to better understand machine level operation and to demonstrate that such modelling is now possible. Predictions for a range of types of hammer mills, vertical and horizontal shaft impactors are presented. The breakage method used is based on fracture
