Jaw crusher blocking material solution

Jaw crusher is the 'pioneer' of the crushing and crushing production line in the mine. Some problems will occur more or less during the crushing operation. Blocking material is one of them. So how do you solve the jaw crusher blocking problem? Jaw crusher blocking phenomenon is what reason?

Zhenxin's machine reminds you that the main reason for skipping and stopping the jaw crusher is that too much material in the lower cavity of the crusher cannot be discharged, and it resists the dynamic cone, causing the motor to overload and stop, usually causing jaw crushing. There are two kinds of situations that cause machine jams;

1, Jaw crusher high output, plate conveyor too late to pull away;

2. The downstream equipment stops and the jaw crusher continues to crush. Once this happens, all the material in the jaw crusher cavity must be sorted out to continue the work. It takes time and effort, usually 3-4 hours. carry out.

In order to prevent blocking, the use of sound and light indicators directly indicate the material, the effect will be better.

Since the operating current of the heavy conveyor under the jaw crusher has a good correlation with the amount of material in the lower chamber, and each time the lower chamber causes the crusher to stop, the current of the panel conveyor must exceed a fixed value. Peak value (38A), no-load current is also a fixed value (18A), so according to the current characteristics of the plate conveyor, you can develop jaw crusher blocking solution.

According to the current characteristics of the plate conveyor, a bell and an alarm flashing lamp are installed at the pouring port of the jaw crusher and are directly connected with the relay inside the electrical cabinet. When the plate conveyor reaches a set current value (33A), the relay When the downstream equipment jumps and stops and the current of the panel conveyor is zero, the sound and light alarm will prompt. The truck driver will stop the feeding after receiving the alarm prompt to prevent it from happening. Jaw crusher blocking phenomenon.

It should be noted that the set alarm value of the panel conveyor should be appropriate, not too low, nor too high. If it is too low, the jaw crusher will often break the material, the stone will be a conveyor, set too high, Cavity volume material will still be too much, even when the blocking material has not been reminded. Buffer space is not enough vibration Xin machine experts practice has proved that the 33A setting value can not only ensure continuous jaw crusher discharge stability, but also to the jaw crusher The cavity has enough buffer space to effectively prevent blocking problems!
