The jaw crusher has a wide range of uses. Under normal circumstances, it is necessary to re-adjust the jaw crusher's discharge opening at an interval of about one month. Through the adjustment of the jaw crusher's discharge opening and the orderly progress of daily maintenance work, not only During construction, unnecessary production losses can be reduced, and at the same time, the service life of the jaw crusher can be effectively increased, and the over profit rate of the enterprise can be increased.

　　First, shim adjustment: use the lifting bolt to open the adjustment seat, and put or remove a set of shims of equal thickness between the rear thrust plate support and the rear w of the frame. By increasing or decreasing the number of gasket layers, the discharge opening of the jaw crusher can be reduced or enlarged. Gasket adjustment can be adjusted in multiple stages, and the machine structure is relatively compact, which can reduce the weight of the equipment, but it be s*ped when adjusting. This adjustment method is often used for large jaw crushers.

　　Second, hydraulic adjustment: Relying on hydraulic pushing cylinder to adjust the discharge port, and adopting the rear thrust plate as the safety device of the jaw crusher. The jaw crusher adopts a hydraulic safety device, which is reliable and safe, and easy to remove faults.

      Third, the adjustment of the support device: refers to the bearing part of the jaw crusher, gener y uses the sliding bearing cast with babbitt oy, which can withstand larger impact loads and is relatively wear-resistant, but the conversion efficiency is low, and it needs Perform forced lubrication.

　　 Fourth, wedge adjustment: It is to realize the adjustment of the crusher's discharge port by means of the relative movement of the two wedges between the rear thrust plate support and the rear w of the frame. Turn the nut on the bolt to make the adjustment wedge move up or down along the rear w of the frame, and drive the front wedge to move forward or backward, thereby pushing the thrust plate or the movable jaw to achieve the adjustment of the discharge port the goal of.
