May 22 2019 therefore in the rolling ball mill the grinding efficiency is increased as the ball diameter decreases it has been proven that the highest grinding efficiency can be obtained with a small ball of mm diameter however the ball diameter is too small to wear too fast and it is also difficult to discharge due to the small gap of the ball
It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation n 0104 d 3 l bap 088 01 l n 1 1 2
A ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell the imagery below helps explain what goes on inside a mill as speed varies use our online formula the mill speed is typically defined as the percent of the theoretical
