An industrial example of its use is for the problem of SAG mill feed rate control, shown in Figure 12, which is notoriously difficult for a PID controller due to the long dead time. Figure 13 shows the results of onoff testing comparing Dahlin and PID control. Jean Rasczak. 5 years ago. Jean Rasczak 5 years ago.

Unlock SAG mill capacity with process control optimization

Unlock SAG mill capacity with process control optimization

Instrumentation. The instrumentation installed on a SAG mill is integral to control. For example, the mill load and noise sensors are instruments that provide essential information for an optimized SAG mill operation. Insufficient understanding of the ore characteristics and feed composition can result in an ineffective SAG mill operation.
