On oscillations of a vibratory jaw crusher with asymmetric

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.

What is a Jaw Crusher? Telsmith

A jaw crusher’s flywheel, toggle plates, pitman, eccentric shaft, and driving motor generate the crushing action and provide the energy needed to break the material. There are some different styles of Jaw Crushers, the most common being the overhead eccentric jaw (shown above) or a double toggle jaw.

Jaw Crusher an overview ScienceDirect Topics

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.

How to solve the Problem of Jaw Crusher Flywheel

Because the jaw crusher is intermittent working, divided into work stroke and idling stroke, resulting in the motor load imbalance. In order to balance the load, the energy of the idle stroke is accumulated when the moving jaw leaves the fixed jaw, so that the energy can be fully released during the working stroke.
