Working Principle

The Jaw Crusher operates on a curved extrusion mechanism:

1. Crushing Phase: The motor drives the belt and pulley, rotating the eccentric shaft to raise the movable jaw. This motion increases the angle between the toggle plate and movable jaw, forcing the jaw plate toward the fixed jaw plate to crush materials.
2. Discharge Phase: As the movable jaw lowers, the toggle plate angle decreases. The jaw plate retracts under spring and tie-rod tension, discharging crushed material from the bottom of the chamber.
3. Cyclic Process: Continuous motor rotation enables cyclical crushing and discharging, ensuring high-volume production.
