This asymmetric segregation within the crusher is not uncommon in real operations and can lead to asymmetry in the wear on the liners and potentially to under-performance of the crusher. Asymmetric loading of a crusher has been demonstrated using DEM simulation of the filling process by Evertsson et al. (2014).
