Ball Mill Operating Principles Components Uses
the balls which could be of different diameter occupy 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.lined mills are charged with flint pebbles, porox balls or arlcite balls and unlined mills use chrome-molloy steel balls. patterson mills are equipped with motor, ring gear and pinion drive, magnetic brake and inching device. type DJ jacketed mills provide controlled temperatures ranging from below to ball mill design. survey of australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters autogenous mills range up to meters in diameter. the length-to-diameter ratios in the previous table are for normal applications. for primary grinding, the ratio could vary between nd cylindrical ball mills differ usually in steel drum design which is lined inside by armor slabs that have dissimilar sizes and form a rough inside surface. due to such juts, the impact force of falling balls is strengthened. the initial material is fed into the mill by a screw feeder located in a hollow trunnion; the ground product
