It appears that DEM is a suitable method for predicting the crushing energy of the spherical rocks in the jaw crusher. The fracture behavior of the crushed rocks was examined and compared by the results obtained from the DEM model. The tensile mode of fracture occurring in the spherical rocks is well presented by the discrete element modeling.

Abstract In this article, a model of the interaction between the jaw of a vibratory jaw crusher with the rock under processing in the form of a lump material is considered. To describe the motion of the rock and its sequential fracture into finer fragments, the crushing chamber is divided into zones of equal height. In each current zone, the material to be processed breaks into smaller

Rock property inhomogeneity allocation assumptions are made. The effect of rock properties on crusher dynamics is studied. The processed rock is considered as a set of discrete elements with varying characteristics during movement along the jaw. The uniformal distribution of the properties of each element entering the treatment zone is considered.
