The ball mill circuit consists of two stages of grinding. The primary ball mill reduces the size of the HPGR product stream which is then sized by hydro cyclone. The ball mills are rubber lined and relines occur every year. The primary mill is 9.0 MW and uses 50mm steel balls, and the secondary mill is 6.2 MW and uses 20 mm steel balls.

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.

For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
