The working efficiency of the ball mill has a great influence on the operation efficiency of the whole mineral processing line. The qualified particle size of the final product of the ball mill directly affects the following mineral processing operation. And the qualified rate of the final product’s particle size is closely related to the feeding size of the ball mill. Next, the relationship between the feeding size and the ball mil will be introduced to you:
When the required particle size of the final product is fixed, if the feeding size is big, the productivity of the ball mill is low. If the feeding size is small, the ball mill’s productivity is high. It is because if the feeding size is small, the ore will stay inside the ball mill for a shorter time and the processing speed is faster.
What should be noticed is that the productivity of the ball mill will change quite obviously with the changes of the feeding size. However, when the particle size is required to be quite fine, the production efficiency of the ball mill does not change very obviously with the changes of the feeding size.
When the feeding size is quite small, the required particle size of the final product is easy to obtain. But, there is a contradiction between the fineness and the production efficiency. When the feeding size is fixed, the productivity of the ball mill will decrease with the increase of the fineness of the final product. The more fine the final product is required to be, the more the productivity decreases. However, in the coarse grinding process, the changes of the fineness of the final product do not affect the production efficiency of the ball mill as obviously as in the fine grinding process.
Above all，in the real production line, each mineral processing plant should select the optimal feeding size for the ball mill according to the scale of the plant and the ore property.
