In the grinding operation,what is appropriate the ball filling rate control？

As we all know, a reasonable steel ball filling rate can not only improve the grinding efficiency and grinding index, but also reduce the ball consumption of the ball mill. In a certain range, the lower the filling rate of steel balls in the ball mill, the lower the processing capacity of the mill; On the contrary, the higher the filling rate, the higher the processing capacity, but the higher filling rate will lead to a decrease in the mill processing capacity, thereby affecting the grinding efficiency.

Under normal circumstances, the filling rate of steel balls in grid ball mills is generally controlled between 40% and 45%.

The filling rate of overflow ball mill is generally controlled between 35% and 40%.

For overflow type ball mill with diameter above 4.8m, the filling rate should be appropriately reduced.
