Why jaw crusher is stuck

The working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), fixed vertically (or slightly inclined at the upper end) on the front wall of the main body, and the other is a movable jaw (moving) with an inclined position A large and small crushing cavity (working cavity) is formed with the fixed jaw. The movable jaws periodically reciprocate against the fixed jaws, sometimes separating and sometimes closing. After separation, the material enters the crushing cavity, and the output is discharged from the lower part. When closed, the material between the two jaws will be crushed due to bending, bending and cracking. What is the reason for the jaw crusher jam?

1. The wearing parts wear out, which causes the crushed size of the material to be too large. During the screening process, the phenomenon of matte materials will appear, which will easily cause the crusher to be blocked.

2. The lubricating oil does not meet the standards. Too much, too little, pollution and deterioration will affect the lubrication effect of the equipment, which will reduce the operating speed of the equipment, * to a reduction in the crushing effect of the equipment. A blockage has occurred.

3. The feed speed is too fast. If the feed is uneven and the speed is too fast during the crushing process, the material in the crushing cavity will not be discharged, which will seriously block the equipment.

4. The discharge opening is not flat. The jaw crusher is generally installed at a higher position. There is a conveyor below the conveyor, but this cannot prevent the material from falling below the conveyor. , Then it will seriously affect the normal emissions of the crusher.

5. The screen under the crusher has problems such as rust and clogging, which can cause slow discharge and damage the crusher.

6. Unstable voltage. When the equipment is damaged, the voltage is unstable and the crusher cannot reach normal speed, which can easily cause equipment blockage.

7. The material is too large and the broken material is too large, which causes serious wear and tear on various parts of the equipment. If the time is too long, clogging will occur. Once the jaw crusher is blocked, it will affect future use and affect work efficiency. Therefore, during normal use, please pay attention to the usage method to ensure that the device can be used normally.
