The importance of uniformly feeding ore during the operation of a ball mill!

Currently, more and more factories and mines in our country are choosing ball mills. When customers purchase ball mills, they also need to learn how to properly increase the feed amount. If the feed amount is increased improperly, it will cause the product particle size of the ball mill to become coarser and increase the amount of returned sand.
Currently, more and more factories and mines in our country are choosing ball mills. When customers purchase ball mills, they must also learn to correctly increase the feed amount. If the feed amount is increased improperly, it will cause the product particle size of the ball mill to become coarser and increase the amount of returned sand. For grid-type ball mills, this may cause the "bloated" phenomenon, i.e., overload. At this time, the mill sounds dull and weak, losing its grinding function. The feed should be immediately reduced or stopped, and the overflow concentration increased. Once the mill returns to normal operation, feeding can resume. If the feed amount is insufficient, the discharge particle size will become finer and the amount of returned sand will decrease. When the feed amount is significantly insufficient, the sound of impact between the liners and steel balls will occur, causing unnecessary wear of the grinding media and liners.
When the feed amount remains unchanged, an increase or decrease in feed particle size will produce similar phenomena to those caused by changes in feed amount. Therefore, during normal operation, the mill must ensure uniform feeding and uniform particle size, with absolutely no large fluctuations. Only in this way can good production indicators be achieved. Whether the ball mill can be fed uniformly mainly depends on the operator's constant observation. Generally, large fluctuations occur during shift changes, so certain areas must be carefully inspected. Inspection items include: the mill's main bearing and drive bearing, the transmission system of the classifier, the operation of the feeder, whether the lubrication oil is sufficient, understanding the replenishment of grinding media, the ore stock in the ore bin, and whether the mill discharge, classifier overflow, and returned sand are normal. Only by carefully doing these can the stable operation of the ball mill and stable production indicators be ensured.
