Four abnormal situations of jaw crusher powder output

During the operation of the jaw crusher, we can't avoid encountering some abnormal situations, which cause the powder output to be too coarse or too fine, or even in serious cases, the phenomenon of no powder blockage. Below we have summarized the four most common abnormal powder discharge situations.

1. Poor sealing of the powder locker. If the Jaw Crusher does not do the job of powder locker sealing during the grinding process, it will form the phenomenon of powder backward absorption, resulting in no powder or less powder, so check the sealing of the powder locker and adjust the sealing degree.

2. Jaw crusher analysis machine does not play a role. The analysis machine of the jaw crusher is responsible for analyzing the size of the finished powder, whether it meets the standard of the finished product, whether it needs sand grinding again, in the case of serious wear of the analysis machine blade, can not play the role of grading, will cause the powder is too coarse or too fine. This situation, replace a new blade can be solved.

3. Jaw crusher fan is not well adjusted. If the air volume of the jaw crusher fan is not adjusted properly, the air volume is too large, which will also cause the mill to produce abnormal powder, the powder will be too coarse, the air volume is too small, the powder will be too fine, in the case of checking other cases without abnormalities, the air volume of the fan should be adjusted to correct the particle size of the powder.

4. The shovel knife of the jaw crusher needs to be replaced. Grinding shovel is responsible for shoveling up the material, when the shovel knife used for a period of time or quality is not hard enough, wear and tear, the material can not shovel, will also cause no powder or less powder, which requires replacement of new shovel knife.
