The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.

Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.

The classifier delivered 33 T. of sand per hour. The total ball-mill feed was therefore 40.37 T. per hr. or 550 per cent, of the original feed. Two Stage Grinding. The object of these tests was to determine the capacity of ball-mills when crushing in two stages. The conditions of the test were as follows: First Stage of Ball Milling

The powder is discharged through the discharge raft to complete the grinding operation. Ball mill is composed of a main part such as a feeding part, a discharging part, a turning part, a transmission part (a reduction gear, a small transmission gear, a motor, and an electric control).

Using the size reduction model to calculate the breakage result of the feed particles inside a ball mill, and using the discharge function to calculate the ground product exiting the mill, the specific energy-based ball mill model is able to extend its applications from batch grinding to continuous operation.
