How to adjust the shim thickness to improve crushing efficiency

When the crusher falls into non-broken objects, an overload protection device is usually installed to prevent damage to important parts of the machine. Shim adjustment devices use bolts to push and use hydraulic cylinder push two adjustment devices. The use of bolts to push adjustment, the use of bolts to push the bracket seat, remove the gasket will increase the discharge port, it is to use the hydraulic cylinder plunger to push the elbow, and then increase or decrease the number of gaskets, so that the exhaust port Decrease or increase then stop the oil supply and tighten the elbow seat with the rear wall with bolts.

When the gasket is added, the discharge mouth should be reduced before the top of the toggle bracket is seated, and the tension spring should be loosened and the press plate bolt should be loosened. Generally, this method is suitable for small and medium-sized crushers. This adjustment device is flexible, labor-saving and convenient, but its structure is slightly more complicated. So it is suitable for large and medium crushers. Hydraulic shims adjustment device is installed on the side wall of the crusher. In this way, in addition to adjusting the discharge opening, the elbow seat can be pressed against the rear wall without additional pressure bolts.

Large jaw crusher due to rarely adjust the discharge port, so often increase or decrease the thickness of the gasket between the bracket and the back wall, or change the length of the elbow method to adjust the discharge port size. The use of hydraulic cylinder push adjustment, with double cylinder dryer, through the adjustment device to change the position of the adjustment seat, you can change the size of the discharge port. During adjustment, the adjustment base slides within its sliding seat.
