When the liner of the jaw crusher is at work, the liner will continue to suffer from the attrition from the ore, which may make the width of the discharging port expand. In order to ensure that the particle size of the products can meet the particle size requirements, the width of the discharging port must be adjusted timely. There are three common adjustment devices for the discharging port.
The first is the gasket adjustment device. The specific approach is to put a group of adjustment pad behind the back supporting seat of the thrust plate. When the number or the thickness of the pad is changed, the back thrust plate will move forward or move backward. The width of the discharging port can be adjusted. This kind of adjustment has the advantages of simple and compact structure and good quality. Therefore, the large and medium jaw crusher plant uses this kind of device. When the device is adjusted, the machine must be stopped.
The second is the wedge adjustment device. The wedge adjustment uses the bolts, turbine lever or the chain drive so that the rear swash iron can be elevated. The front swash iron is installed in the guide slot between the side wall in the rack so that it can move horizontally. When the back oblique iron is raised, the thrust plate and moving jaw can also move forward. The width of the discharging port will also reduce. When the oblique iron descends, the width of the discharging port will increase. The device can achieve the infinitely variable control. In the adjustment process, the size of the whole machine size increases. Therefore, the crusher machine only applies to the medium and the small jaw crusher.
The third is the hydraulic adjustment device. Such adjustment means uses the hydraulic cylinder and the plunger to adjust the width of the discharge opening. In the adjustment, you can first tense the screw of the spring and open the stop valve and start the stop valve. Then you should open the stop valve.
