For any load change the two flows readjust their positions to deliver the required PA flow. For higher load the bypass damper tends to close to allow less flow for preheating of raw feed and the PA damper to the mill opens more to take care of the load demand. Some alternative systems for ball-and-tube mill controls are presented in Section 4.4.4.

autogenous (SAG) mills were first used on ores in the 1950s but they were not seriously considered by the autogenous mill with an 8 ball charge. The test is run until a steady-state is achieved similar to the Bond rod mill and the entire mill load is returned to the mill the set-point is adjusted to increase or decrease the mill load
