In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 s. This means that 77.1 per cent of the particles in the mill are coarse and that 77.1 per cent of the mill power is being used effectively. Conversely, 100-77.1, or 22.9 per cent of the mill contents are fine and are being.
Where the SAG millball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity. The pebble circuit recirculating load can be very significant depending on the ore characteristics and SAG mill operating dynamics. Ore sorting prior to secondary crushing of the.

Discharge mill in open circuit with a charge in equilibrium with a 60 mm ball top-up and a 32.4 ball filling degree. The data see Table I and particle sizes see Graph 1 are mentioned. Overall, the repeatability is good as the variations between tests 8 and 9 are small. There is only a 10 m.
Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, AG mills, or SAG mills. in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill.
Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill two stage circuit, or a semi-autogenous grinding SAG mill followed by a ball mill two stage circuit.
