As a commonly used grinding equipment, the output of ball mill is an important indicator to measure the quality of the ball mill. So what are the factors that affect the output of the ball mill?

1. Mill volume. Generally, the larger the volume of the mill, the greater the processing capacity.

2. The water content of the material. If the water content of the material is too high, it will affect the uniformity of the feeding and make the feeding time too long. Secondly, if the wet material is fed too much, it may cause the phenomenon of "sticky grinding". Therefore, the feed moisture is usually required.

3. Loading capacity of grinding body. After the mill runs for a period of time, the output will decrease. This is because with the impact and grinding of the grinding body in the cylinder, the grinding body will wear out, so the grinding body must be refilled in time. But it is not that the more abrasives, the better. If the steel balls accumulate too high, the impact of the steel balls on the material will be slowed down, and on the contrary, the grinding output will be reduced.

4. Grinding time. Too short grinding time will result in insufficient grinding of materials. In addition, frequent starting of the mill will shorten the service life of the equipment. If the grinding time is too long, the temperature in the cylinder will increase, which will affect the grinding efficiency.

5. The ball mill is "full grinding". After the ball mill has been running for a period of time, due to the excessive feed of the ball mill or the increase in the particle size of the material, or the excessive moisture of the material entering the mill, the grate gap of the grate plate is blocked; the material in the mill cannot be discharged out of the mill in time, the phenomenon of "full grinding" appears, which affects the output of the ball mill. In this case, it is necessary to adjust the materials, clean the grate seams, and increase the ventilation in the mill.

6. Adding ratio of grinding aid. Grinding aids can promote the grinding of materials, but most of the grinding aids are substances with strong surface activity and are not suitable for all materials, so the amount of grinding aids added should meet a certain proportion.

When the output of the ball mill is found to be lower and lower during the production process, it should be investigated in turn to find out the problem and resume production as soon as possible.
