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
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration Figure 2 shows that there is no linear relation between
The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet
