This paper is devoted to the problem of providing the required synchronous modes of oscillations of a jaw crusher with self-synchronizing inertial vibration exciters. The described mathematical model of the crusher takes into account the mechanical properties of the medium being processed and the possible asymmetry of its contact with the crusher’s working bodies – the jaws.

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher. Measuring Discharge Opening: Measure distance at bottom of jaws at the point of the crushing cycle when the bottom of jaws is closest together.
