Why does the jaw crusher suddenly stop moving

Through our company’s return visits to customers, we found some problems. Among them, the higher heat is the sudden "strike" of the jaw crusher, making users helpless. At this time, you must take the correct method to solve it, otherwise, it may cause more serious problems. The problem may even affect the service life of the jaw crusher.

The two main factors of jaw crusher strike:
  1. Engagement angle: The engagement angle 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. As the biting angle increases (increased crushing ratio), the yield will decrease. Adjusting the size of the discharge port also changes the size of the angle of engagement. Therefore, it is fair 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 yield.
  2. Number of revolutions: within a certain range, increasing the number of revolutions of the eccentric shaft can increase the production capacity of the crusher, but it will also increase the power consumption per unit weight of ore. If the rotation speed is too large, the crushed ore in the crushing cavity will not be discharged in time, and blockage will occur, which will reduce the production capacity and increase the power consumption. Therefore, the jaw crushing equipment should have a relatively suitable number of rotations.
If your jaw crusher or cone crusher is on strike during use, don’t worry at this time. You can check the problem with the above two common factors. You may also pay attention to our website at any time. I believe you Will find the correct solution.
