Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …

Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.

Tramp metal in the ore such as scaling bars and rock bolts cut the rubber and can become lodged in the grate openings. This puts an excessive strain on the grates. When the mill rotates the metal is pushed and twisted by the ore. This stretches the rubber and can cause severe damage to the face and the back of the grate.

When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball mills.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. 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.
