Jaw crusher operation and maintenance | Henan Deya
Jaw crushers are generally installed on top of the concrete foundations. Take into consideration of the weight of jaw crusher, the tough working conditions and the high inertia forces generated by the machine during operation, which may cause the slight vibration of foundation and machine system; therefore, the foundation of the jaw crusher should be separated from the foundation of the workshop.

Jaw Crusher Working Principle
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.

Dynamic analysis of a vibratory jaw crusher with inclined
Abstract: In this article we investigate the dynamics of an inclined vibratory jaw crusher, in which oscillations of the jaws are excited only by one inertial vibration exciter, located on the upper jaw. The laws of forced oscillations of the jaws are obtained. The conditions for existence of the symmetrical form of forced oscillations (an ideal operating mode of the crusher) are introduced.
