mill. Worsley Alumina ... Systems optimisation is an ongoing process involving the use of frequently measured and calculated system inputs, in order to manage and optimise productivity and quality. It sits above existing process control systems, which are widely used to monitor and control
If the mill feed setpoint is changed, then the actual feed rate needs to stabilise at the new target in a short period of time. The feed rate setpoint can then be tied into a SAG mill power optimisation strategy. SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classification ...

ABB's extensive and worldwide experience in implementing pulp mill optimization and control packages is proven with more than 500 systems installed since 1969. The process expertise coupled with this extensive experience has resulted in new and improved advanced process control () solutions for pulp mills packaged under the OPT800 suite.
the mill and the balance of material flows through the system, it is possible to identify situations when the feed to the mill and the output can be increased. Increased output over extended periods of time has been observed on mills controlled by Expert Optimizer. • Reduced power consumption. This important saving is a result of the softer
The Solution. Using BlendOpt and collaborating with Paradyn, the customer investigated how changes to ROM stockpile definitions, combined with optimisation of reclaim across time, impacted Cu and Cu:S mill feed quality and stability. While satisfying constraints in the value chain: crusher capacities, ROM stockpile and crushed ore bin ...
