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.

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.

The ratio of the trunnion thickness to trunnion diameter in a mill of 2,134 m diameter is almost twice that of a mill of 5,8 m diameter, a ratio (T/D) of 0,116 to 0,069 for the large mill. However the design stress levels at the trunnion/head transition in the case of the large mill are almost 250% of those in the small mill.

where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
