Commonly used methods to adjust the thickness of the discharge are as follows:
1. Gasket adjustment
Use jack bolts to open the adjustment seat, put in or take away a group of gaskets with equal thickness on the rear thrust plate support and the rear wall of the frame, and increase or decrease the number of gasket layers to make the discharge of the crusher The feed opening decreases or increases. This adjustment device has a simple and compact structure, and the weight of the whole machine does not increase much, so it is more commonly used.
2. Hydraulic adjustment
The rear thrust plate is used as the safety device of the crusher. Generally, the jaw crusher adopts a hydraulic safety device, which can automatically adjust the size of the discharge port, which is reliable and safe, and easy to discharge faults.
3. Use inclined iron to assist adjustment
The transmission device can be used to make the rear inclined iron move up and down, and the front inclined iron moves horizontally. When the rear inclined iron is lifted or lowered, the size of the discharge opening can be adjusted accordingly. This adjustment device can realize stepless adjustment. When adjusting No parking required either.
4. Electric control adjustment mechanism
The electronically controlled adjustment mechanism can quickly realize the adjustment and inspection of the jaw crusher. It is convenient to control the particle size series, avoids repeated operations, and provides a maximum degree of discrimination and accuracy.
5. Adjustment of support device
In the bearing part of the jaw crusher, a sliding bearing cast with Babbitt alloy is used, which can withstand large impact loads and is relatively wear-resistant, and requires forced lubrication.
