In this research, numerical model of vibratory jaw crusher dynamics is considered. Its operating components commit a plane-parallel motion. Treated rock is a complex rheology structure: it has viscoelastic behavior and inner dry friction, variable pressure is constantly presented, whereas dissipative properties are unilateral and appear while approaching the jaws.
