If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. When hard pebbles rather than steel balls are used for the grinding media, the mills are known as "pebble mills." As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations.

The name "ball" or "pebble" refers to the type of grinding media that is introduced into the mill. The media when combined with ores or other subtances accelerate particle size reduction by virtue of their impacting on the particles as the mill rotates. The grinding action is as described in our article about how grinding mills work.

The size distributions of the balls and the pebbles were calculated to simulate steady-state addition of balls (37.5 mm) and partly-rounded pebbles (19-75 mm). There was a reduction in pebble consumption, as expected, when using larger rounded pebbles, to about 6% of total production. The grinding capacity, when using a mixture containing 25% ...

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm).

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19-75 µm). Batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble mixtures.
