There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
The total feed to the ball-mill was therefore 11.54 T. per hr. or 179 per cent, of the original feed. It was evident that the ball-mill was greatly underloaded in this test, but so much trouble developed in the classifier, due to the tendency of the sands to slip down the slopes, that a more rapid feed was not attempted at this time.
In this example the SAGDesign (SDT) ore hardness is 10 kWh/t (to grind the ore from F 80 152 mm to T 80 1.7 mm) and the SAG ground Bond Ball Mill Work Index is 15 kWh/t. Table 2 shows alternate equipment selections that will produce 471 t/h, (10,400 t/d and 3.8 million tonnes per annum) at 92% availability.
