Using Ball Mills to Extract Raw Gold from Ores - RareGoldNuggets

To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is suspended on its axis to bring about rotation.
