Method for adjusting the discharge particle size of jaw crusher

The adjustment device of the jaw crusher is an adjustment mechanism for the size of the discharge port of the rock crusher. With the operation of the equipment, the wear of the crushing tooth plate increases, and the discharge port gradually increases, and the size of the crushed product continues to become coarser. In order to ensure For product particle size requirements, an adjustment device must be used to adjust the size of the discharge port regularly. The following is the adjustment method of jaw crusher discharge particle size:

1. Hydraulic adjustment

At present, there is a hydraulic drive cylinder installed in the position of the adjusting device to adjust the discharge particle size. When foreign matter enters the crushing cavity of the whole set of rock crusher equipment, in order to prevent damage to the machine, the rear thrust plate is used as the safety device of the rock crusher. The whole set of rock crusher equipment adopts hydraulic safety device, which is reliable and safe, and easy to discharge faults. The size of the discharge port can also be adjusted.

2. Gasket adjustment

Use the jacking bolts to open the adjusting seat, check the quality of the rear thrust plate support and the rear wall of the frame, and put in or remove a set of gaskets of equal thickness. By increasing or decreasing the number of shim layers, the discharge port of the rock crusher can be reduced or enlarged.

3. Adjustment of supporting device

The supporting device of the whole set of rock crusher equipment is mainly used to support the eccentric shaft and the suspension shaft to fix them on the frame. At present, rolling bearings have gradually replaced sliding bearings, which not only reduces friction loss, but also has the advantages of simple maintenance, good lubrication conditions and oil leakage. The adjustment of the supporting device can also control the size of the discharge port.

4. Wedge adjustment

The wedge adjustment of the whole set of rock crusher equipment mainly uses the relative movement of the two wedges between the rear thrust plate support and the rear wall of the support to realize the adjustment of the size of the discharge port of the whole set of rock crusher equipment. The nut on the bolt makes the wedge move up or down along the rear wall of the frame, drive the front wedge to move forward or backward, push the thrust plate or the movable jaw, so as to realize the adjustment of the discharge port.
