(PDF) DEM Simulation of Laboratory-Scale Jaw Crushing of

Laboratory-scale jaw crusher at the Colombian Geological survey, with the insert showing the top view of the crushing chamber. Figure 3 shows the jaw crusher scheme indicating the main components,DEM Simulation of Laboratory-Scale Jaw Crushing of a,The present work describes the modeling and simulation of a laboratory-scale jaw crusher using DEM with the particle replacement model embedded to describe product size distribution, throughput and crusher power. The PRM has been implemented as a modification of the Hertz-Mindlin contact model, through which each spherical mother particle is replaced by a distribution of daughter sphericalLaboratory Jaw Crusher - 911Metallurgist,The Model 911MPCJC200D Jaw Crusher is used by laboratories and processing companies to crush solid materials such as rocks or soil and ores. The material to be processed falls into the crushing chamber of the 911MPCJC200D Crusher via a guide chute and is crushed by crushing action of a static and a dynamic jaw plate until it passes the preselected gap of the crusher. The stepless gap setting can be adjusted via a hand wheel and a mm scale from 0 mm to 25 mm (contact of the jaw
