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,Model predictive control of semiautogenous mills (sag,,Oct 01, 2014· 2.4. Multivariable predictive control. In the present work, a three-input-three-output scheme of control was performed. The total water feed to the mill (the feed water flow rate was added to the dilution water flow rate, so they could be specified separately, but for the SAG mill model, the total water content was the variable of interest), the fresh ore feed rate, and the mill rotation speed,MILLING CONTROL & OPTIMISATION - MINTEK,Figures 8 and 9 on the right show results from a gold plant’s SAG mill achieved with MillStar’s Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes.

Using Fuzzy Control to Optimize SAG Mill Production

fuzzy SAG mill control system. Although, while relatively unknown, fuzzy control systems have already proven their value in a number of grinding control systems as compared to more traditional crisp expert control systems. This partially due to the fact that fuzzy logic is naturally easy to understand and maintaining a control strategy specified inIntegrated advanced process control with a sag mill,,The control strategies were developed with the following main goals in mind: SAG mill weight stability and preventing of over filling of the mill Reduction of undesirable critical impacts, trough the integration with the impactmeter SAG mill throughput optimization and improve energy efficiencyRevolutionary Drive Controller for Gearless Mills,The controller features critical monitoring during the starting period, protecting the mill against damage when dropping a frozen charge. As the loaded mill starts up, the control system evaluates torque build-up, ensuring that appropriate decisions are taken before a frozen charge can drop and damage the mill body or the mill bearings.
