Forces on ball in ball mill as the angle α decreases however the centripetal force increases and unless the speed exceeds the critical a point is reached where the opposing forces are equal and the particle is ready to fall awayThe angle at which this occurs is found by equating the two forces giving at the critical speed α 0 cos α 1 and n becomes the critical speed n.
