Ball mill should keep even feeding in operation; the even feeding means stable feeding quantity and same particle size distribution.
Unsuitable feeding would make the product size become bigger, and bring more return capacity, which cause "Bloated" phenomenon for ball mill. It also means overload of the ball mill. Under this situation, the operation voice sound dull and weak, which means lost the grinding function. At the moment, operator should immediately reduce or stop the feeding, and improve the overflow concentration. Feeding again after the normal work is resumed
Inadequate feeding would make the product size become smaller, and bring less return capacity, which cause the impact between linear and steel ball. The extra impact will lead to consumption increasing.
Feeding size increasing or decreasing also causes the same results as feeding capacity when the feeding capacity is fixed.
Only even feeding and proper size will bring good production indexes. We should pay attention to these two factors
