High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

A roller mill can efficiently break down grain for livestock feed. Energy efficiency is especially pronounced in electric grain roller mills. In some situations, roller mills use 85% less energy to process grain than hammer mills. In the most common processing situations, though, the energy savings are likely 3050%.

In mining industry, ball mills normally operate with an approximate ball charge of 30% with a rotational speed close to 11 rpm. The mill is fed at one end of the cylinder and the discharge is at the other. Ball mills can be driving by medium voltage motors or wrap around motors, knows as Gearless Mill Drives (GMD).
