impact mill theory of operation. california pellet mill co. 3 terms used in pelleting the following terms are often used to measure the efficiency and quality of pellet mill operation. friction is the difference in temperature of the feed entering the pellet mill die and the pellet being discharged from the die. the difference reflects the mechanical energy required to
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed

The impact energy acquired depends on the speed of the planetary mill and can reach about 20 times the earths acceleration. As the speed is reduced, the grinding balls lose the impact energy, and when the energy is sufficiently low there is no grinding involved; only mixing occurs in the sample.
The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
