Gold Mining Stone Crusher Large Crushing Ratio Jaw Crusher For Hard Stone

Brief Descriptions of Stone Crushing Equipment:

Jaw crusher is ideal for primary and secondary crushing. It is widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys.

With the increase of production, our stone jaw crusher can greatly reduce the operating costs. And it is of reliability and flexibility. The large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our stone jaw crusher can increase the capacity. The jaw has a smaller discharge setting, allowing for a higher degree of flexibility with relative equipment. Positive setting adjustment is easy.

Working Principle of Mine Jaw Crusher:

1. Jaw crusher mainly consists of frame, eccentric shaft, jaw plate, connecting bar, adjustment part and spring.
2. The movable jaw goes upward and downward through eccentric shaft when belt and belt wheel are driven by the motor.
3. The angle between movable jaw and bracket turns big when the movable jaw goes upward, which pushes the movable jaw plate to come closely to fixed jaw plate.
4. At the same time, materials are crushed with the movement of the movable jaw. When the movable jaw goes downward, the angle between movable jaw and bracket turns small.
5. Under the force of spring and connecting bars, the movable jaw plate leaves fixed jaw plate, and the crushed materials with qualified size are discharged from the crushing cavity.
6. With the continuous rotation of the motor, the movable jaw crushes and discharges materials, which, in turn, realizes the goal of mass production.

Main Features of Stone Jaw Crusher:

The Jaw Crusher is configured for primary crushing of even the hardest rock. Incoming material is crushed between the jaw crusher’s fixed plate and movable plate through advancing and retreating motions of the jaw crusher pitman arm. The Jaw Crusher main shaft bearing includes a dust seal with oil bath lubrication.

1. Roller bearings provide strength & safety. Oil bath lubrication ensures longer service life.
2. Toggle plate, toggle block, and toggle seat protect the jaw crusher from damage caused by uncrushable material in the crushing chamber. This construction helps to maintain a stable crushing angle.
3. Simple & quick discharge gap adjustment, precise product grain distribution.
4. Large & deep crushing chamber with sharp crushing angle, to achieve a very high crushing ratio.
5. The Jaw Crusher with bigger feed opening and longer pitman arm is especially suitable for primary crushing.
