Jaw stone crusher is crushing equipment commonly used in the mining industry for rough crushing. It can crush rocks with high hardness and abrasiveness, such as granite, quartzite, diabase, basalt, etc. However, with the wear of the crushing toothed plate, the ore discharge port of the jaw crusher will gradually increase and the particle size of the crushed products will become coarser. In order to ensure the requirements of product particle size, we must use the adjustment device to adjust the size of the ore discharge port regularly.
1. Gasket adjustment.
We can use the top bolt to open the adjustment seat of the jaw stone crusher machine and put or remove a set of gaskets of equal thickness between the rear thrust plate support and the rear wall of the frame. Increase or decrease the number of gasket layers to reduce or increase the discharge port of the stone jaw crusher. The gasket can be adjusted in multiple stages, and the whole machine has a compact structure, which can reduce the weight of the equipment. But the operator had to stop working. This method is widely used in large jaw crushers.
2. Wedge adjustment.
It is the relative movement of the two wedges between the rear thrust plate support and the rear wall of the frame to realize the adjustment of the outlet of the jaw crusher equipment. Turn to the nut on the bolt to make the adjustment wedge move up or down along the rear wall of the frame, and drive the front wedge to move forward or backward, thereby pushing the thrust plate or moving the jaw to achieve the adjustment of the discharge port the goal of.
3. Hydraulic adjustment.
We can adjust the discharge port by hydraulic pushing cylinder and adopt the rear thrust plate as the safety device of the jaw crushing machine. Safety devices are a safety measure to effectively prevent the machine parts from being damaged when the crushing cavity of the jaw crusher enters the non-crushing object. The stone jaw crusher adopts a hydraulic safety device, which is safe and reliable, and easy to troubleshoot.
4. Supporting device
Refers to the bearing part of the jaw crusher stone machine. Large and medium-sized crushers generally use cast Babbitt alloy as the sliding bearing, which is convenient for him to withstand larger impact loads and is more wear-resistant. But when it is inefficient, forced lubrication is required. With the improvement of rolling bearing manufacturing technology, large-scale jaw crushers will also use rolling bearings in the future, which is not only convenient but also efficient.
The above is the adjustment method of the jaw crusher discharge port.
