: The principle of ball mill is based on impact attrition . At rapid speed impact occur as the moving balls hits the materials that comes in between them while the attrition occurs at low speed because the ball moves over each other . Large balls break down the coarse feed material . Smaller balls help to form fine product by reduction void space b/w the ball .

14. High ball milling: Ball milling process where a powder mixture placed in the ball mill is subjected to highenergy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method, termed mechanical alloying, could successfully produce fine, uniform dispersions of oxide particles (Al2O3 ...

A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
