sag mill control fl. Robust control of a SAG mill - ScienceDirect. SAG mill control. In general terms, the benefits sought from improved primary grinding circuit control include increasing throughput at the desired grind size, reduction of grinding ball consumption and minimisation of the SAG mill power requirement. In the absence of an ...

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

As a result the mill operator is left with the power draw on the secondary mill motor as the only positive measurement of a process variable to guide him in operation and control of the circuit. If the operator has a mass flow measurement on the cyclone feed and the cyclone overflow, the cyclone underflow can be calculated by difference.

Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...

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 on/off testing comparing Dahlin and PID control. Jean Rasczak. 6 years ago. Jean Rasczak 6 years ago.
