Operation principle of jaw crusher:

The motor drives the belt and the grooved wheel, which connect the eccentric shaft. Through the movement of eccentric shaft, the movable jaw plate moves up and down. When movable jaw plate moves up, the angle between it and toggle plate will be enlarged, so the movable jaw plate will be close to fixed jaw plate. Then, the materials will be pressed and crushed; when movable jaw plate moves down, the angle between it and toggle plate will be reduced, movable jaw plate will moves away from fixed jaw plate due to the tension rod and springs. At this moment, the crushed materials will be discharged at discharge opening. With moving of motor and periodical movement of movable jaw plate, material will be crushed and discharged gradually, so that batch production will be reached.

Jaw crusher features:

1. Huge oversized heat treated shafts forged of special alloy to handle overloads and hard material.

2. Extra large, radial thrust tapered roller bearings absorb and withstand extreme shock, radial and thrust loads and offer substantially more bearing life than competitive models.

3. Much heavier, stronger, massive one piece frame, stress-relieved for optimum reliability.

4. Toggle bearing wedges for easy in, easy out bearing replacement.

5. Hardened barrel wear liners protect the pitman.

6. Replaceable toe wear liners on swing and stationary jaw.

7. Larger stroke, deeper crushing motion, steeper nip angle means higher capacity and greater throughput.

8. One piece cast pitman stands up to the most demanding crushing applications.

When you need a truly massive jaw unmatched in reliability, high capacity, and high productivity, you need a Zenith. Zenith's range of large model jaws includes PE600×900，PE750×1060,PE900×1200,PE250×1200 to suit your particular heavy duty, high volume crushing application. Compare a Zenith jaw crusher with any other jaw crusher on the market. Immediately you’ll see this machine was built for demanding production, strength and a lifetime of dependability.
