The ball mill adopts a discharge screen similar to the ball mill and the function of blocking the internal medium of the overflow ball mill is accomplished inside the rotary part of the ball mill the discharge screen is only responsible for forcing out a small amount of the medium that overflows into the discharge screen through the internal
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a mill geometry and speed – bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account as well mills with different
The grinding effect of the ball mill directly affects the grinding efficiency and the output of the ball mill in addition to considering the size of the ball mill internal structure of the ball mill product fineness requirements and other factors should also consider the characteristics of the grinding material such as grindability particle size
The larger feed size the more work that the ball mill needs to do on the ore to achieve the specified grinding fineness the workload of ball mill will be increased inevitably and then the energy consumption and power consumption will be increased
