Usually, when the ball mill is just put into operation, the output will remain normal, but after running for a period of time, the output may become lower. What is the reason for the lower and lower output of the ball mill?
01 Ball mill "full grinding"
The causes of "full grinding" are: excessive feeding; The hardness and particle size of the grinding materials become harder and larger; Compartment plate or discharge grate plate, grate gap blockage, etc. Solution to the problem of "full grinding": reduce the feeding amount; When the size or hardness of the grinding material changes, corresponding adjustment shall be made in time; Clean the blockage of compartment plate or castor joint, and increase the ventilation of ball mill cylinder.
02 The grinding body was not added in time
The grinding effect and output of the ball mill are restricted by the grinding body of the ball mill. However, with the grinding and impact in the cylinder, the grinding will be worn. Therefore, the grinding body should be added in time to ensure the consistency of the output of the ball mill to the greatest extent.
03 Material moisture content is too high
Because the material moisture is large, it affects the uniformity of feeding and prolongs the feeding time. Secondly, due to excessive feeding of wet materials, the phenomenon of paste ball and paste lining plate in the mill may occur, and even "full grinding" and forced to stop grinding.
04 The addition proportion of grinding aid is unreasonable
Grinding aids are allowed to be added in the production process, but the amount shall not be too high. It is unreasonable to add more than this standard. In addition, grinding aids are mostly substances with strong surface activity and are not suitable for all materials. They should be added reasonably according to the properties of materials.
If the output of the ball mill is getting lower and lower, it can be checked in turn according to the above reasons, find the crux of the problem, completely solve the problem of low output from the root, and resume production as soon as possible.
