The cause of the "blowing" is mainly due to the increase in the amount of minerals and the change in the amount of water (water pressure) caused by the sharp increase in grinding concentration. The sound becomes dull, I can't hear the impact of the steel ball. Observing the ammeter can see the current drop, which means that the motor has the least work at this time, and the mill has lost the grinding effect. If not promptly adjust, and soon the cylinder body material will cause the loss of metal from the mine to the mill spit out (commonly known as lean pull). Deal with the phenomenon of "swelling belly", the operator should not panic. It is necessary to first turn off the feeding machine, stop the feeding, and increase the amount of water in the rear of the mill. The discharge of the ore is appropriately reduced to increase the overflow concentration of the classifier. The purpose is to reduce the amount of returning and reduce the load on the mill. After careful treatment and adjustment, it usually takes about half an hour to return to normal, and some serious ones are still longer. When it is found that the discharge concentration of the discharge port is thinner and the discharge amount is gradually reduced, the sound of the steel ball striking the lining can be heard; the current meter can be found to return to normal, and these phenomena all indicate that the "flatness" has been solved. At this moment, the mine and other operating conditions should be restored to make the mill work normally.

The concentration of grinding concentration is directly related to the amount of ore. If the concentration is too large or too small, it will have an adverse effect. When the concentration is too large, the slurry flow rate is slowed down, and the impact of the grinding medium (steel ball, steel rod) becomes weak. For overflow ball mills , the concentration of the ore may be thicker; while the lattice ball mill may show swelling.
