Ball Mills Mineral Processing & Metallurgy
Cataracting 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).Feb 14, 2018 A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.
