MoreCataracting balls hit the mill shell, causing ball-to-wall collision. Finally, the surging impact is when balls collide in midair, which results in ball-to-ball collision (Mishra and Rajamani, 1992). Surging of the charge may take place at all speeds and it is particularly damaging at high speeds (Behera et al., 2007).
