8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter . The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Under other conditions, it is better to use a wet ball mill which has a better grinding effect, and energy saving performance. 2. Energy consumption Choose an energy saving ball mill or ordinary ball mill according to the capacity of electric power supply and energy consumption limitation. 3. Capacity

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.

Answer : Firstly, the movement plane of the medium in the ball mill is perpendicular to the gravitational field, and the medium movement must overcome the gravity to do work, so the grinding energy consumption is high.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
