Jaw crushers are usually used for the * crushing of the entire production line. If there is a problem, the entire production line will not work. However, if the operation method is not grasped, the jaw crusher will often crash, so the material is being crushed. At the same time, we need to pay attention to the uniformity of the material and the hardness of the material. If it is too hard, it needs further processing.

Under normal circumstances, the main factors affecting the work of the jaw crusher are the angle of engagement and the number of revolutions. The angle of engagement is the angle between the movable jaw and the fixed jaw. According to the calculation, the maximum engagement angle can reach 32 degrees. In actual use, it is less than 25 degrees, generally around 18-20 degrees. If the biting angle is too large, the ore in the crushing cavity will be squeezed upwards, which may injure people or damage other equipment. At the same time, as the biting angle increases (the crushing ratio increases), the productivity decreases. Adjusting the size of the discharge port also changes the size of the angle of engagement.

In actual life, the size of the discharge port is adjusted according to the requirements of the discharge particle size. Therefore, it is reasonable to enlarge the discharge port as much as possible under the requirement of ensuring the product size. The size of the discharge port can be adjusted by adjusting the block. When adjusting the size of the discharge port, pay attention to the relationship between the crushing ratio and the productivity.

The eccentric shaft, connecting rod, movable jaw plate, shaft and liner of the jaw crusher are the main wearing parts, which require frequent attention to lubrication and replacement. Through the above introduction to the crash situation of the jaw crusher, we can clearly know the jaw crusher. If we encounter problems, we can use the above methods to investigate.
