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:
