How To Adjust The Gap Of Jaw Crusher?

Jaw crusher is a common mining crushing equipment. It is used in: mining, construction, metallurgy, building materials and other industry fields. Jaw crusher in the process of its clearance is crucial. It determines the granularity of the discharged material. It also directly affects the crushing effect and crushing efficiency of the material.

Jaw crusher is mainly composed of: fixed jaw plate, movable jaw plate, transmission device, hydraulic device and so on. The material is sent to the crushing chamber through the vibrating feeder. Through the mutual extrusion and friction between the fixed jaw plate and the movable jaw plate, the material will be crushed into the required size. The material will be crushed into the required size. Jaw crusher only needs to adjust the gap. In fact, it is by adjusting the spacing between the fixed jaw plate and the movable jaw plate.

There are many ways to adjust the gap of jaw crusher: shim adjustment, wedge adjustment, hydraulic adjustment and other methods.

1. Gasket adjustment: commonly used in adjusting large jaw crusher. The shims are mainly located between the rear wall of the frame and the rear thrust plate bracket. By increasing or decreasing the number of shims. Then the gap size between the fixed jaw plate and the movable jaw plate can be adjusted. So as to control the granularity of the discharged material.

2. Wedge adjustment: it is often applied to small and medium-sized jaw crusher. Through the wedge between the thrust plate support and the back wall of the frame to move each other, so as to control the size of the discharge size of the jaw crusher. To increase the size of the discharge, the turning nut can be adjusted. Use the wedges to descend along the rear wall of the frame. Push the front wedge to move backward. Push the elbow plate to move backward on the movable jaw plate. Thus increasing the feed opening. If you want to reduce the feed opening. Then it can be operated in the opposite direction. At present, there are two ways of wedge: mechanical and hydraulic.

3. Hydraulic adjustment: Hydraulic adjustment is to replace the traditional manual adjustment. The size of jaw crusher discharge is controlled by hydraulic adjusting lever. At the same time can be equipped with electronic control system. The controller gap size can be operated directly through the button.

Jaw crusher in long-term operation. Need to regularly adjust the jaw plate gap. Ensure that the equipment can run efficiently. It controls the size of the discharged material. Weekly can be tested: 2-3 times. According to different equipment operating hours and material properties. Thus the frequency of adjustment is appropriately increased or reduced.
