Reasons for jaw crusher blocking and general solutions


If the jaw crusher is blocked, it will affect the normal work of the jaw crusher, thus reducing its production efficiency. How to solve the problem of material blocking in jaw crusher? The following is about the cause of jaw crusher blocking material and solutions.
The main reason of jaw crusher stopping is that there is too much accumulated material in the lower chamber of jaw crusher, which can not be discharged, and the motor is overloaded and stopped. Generally, there are two kinds of situations causing skip stop: the first is that the output of jaw crusher is high and the plate conveyor is too late to pull away; the second is that the downstream equipment stops and the jaw crusher continues to break. Once this happens, all the materials in the crushing chamber must be cleaned out before the machine can be started. It is time-consuming and laborious. Generally, it takes an hour to complete.
In order to prevent blocking, we use the sound and light indicator to direct the pouring. Because the running current of the heavy conveyor under the jaw crusher has a good correlation with the amount of materials in the lower chamber, and each time the lower chamber causes the jaw crusher to stop, according to the current characteristics of the plate conveyor. The solution is to install an electric bell and an alarm flashing light at the discharge port of the jaw crusher, which is directly connected with the relay in the electrical cabinet. When the plate conveyor reaches a set current value, the relay will close, the alarm lamp will start to flash and the bell will ring. If the downstream equipment jumps and stops and the plate conveyor current is zero, the sound and light alarm will also prompt. After receiving the alarm, the tramcar driver will stop dumping to prevent blocking.
