size of ball in ball mill

Ball millsare among the most variable and effective tools when it comes tosizereduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials makeball millsthe perfect match for a vast range of applications.

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 occupy30 – 50 % of the mill volumeand its size depends on the feed and mill size.

When theball millrotates, theballmovement in the barrel may have three states (pic 8-1).

Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
