Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers. Theoretical size reduction and power ranges for different grinding mills [image: (135-6-1)] AG/SAG Mills Autogenous Grinding (AG) Mill. Wet or dry; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed
For a given size mill and particle, but with an extremely small ball, the rate of grinding will be low; since the ball will not contain sufficient energy to produce much new surface. With increasing ball size, however, the rate of grinding will increase since the increased energy will bring about increased surface production per blow.
