DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls. The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient

The development of a validated computational simulation model of a cone crusher could significantly reduce the required lead time and costs. The discrete-element method (DEM) ( Cundall & Strack, 1979 ) provides a potential method to investigate the mechanical behaviour of the flow and breakage of granular material at both micro and macro scales.

Dynamic models of the cone crusher (Evertsson, 2000, Sbárbaro, 2005), screens, conveyors and silos, and equipment wear dynamic models were combined with a discrete event simulation model that incorporates events such as maintenance, stops, and delays. When necessary, control loops were closed using PI controllers; however, limited attention
