### ball mill: operating principles, components, uses

a ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. 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.

ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

a ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.it works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. a ball mill consists of a hollow cylindrical shell rotating about

a sag mill with a 44' (13.4m) diameter and a power of 35 mw (47,000 hp) has been designed. attrition between grinding balls and ore particles causes grinding of finer particles. sag mills are characterized by their large diameter and short length as compared to ball mills.

the ball impact energy on grain is proportional to the ball diameter to the third power: 3 e k 1 d b. (3) the coefficient of proportionality k 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). none of the characteristics of the material being ground have any influence on k 1.
