Optimum ball charge in a SAG mill is a function of many factors. Some are discussed below. For a SAB or SABC circuit. In general the higher the ball charge the higher the throughput (and fine feed helps as well). Of course you need a bigger ball mill. But high ball loads mean higher ball consumption in the circuit.
