摘要：

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 of particles using geometric rules for progeny generation and estimates of the stress applied to the particles as they flow through the crusher. From these simulations, estimates of power, product size, throughput rate and crusher wear are made. Crown Copyright (C) 2014 Published by Elsevier Ltd. All rights reserved.
