When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally singlestage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted ...
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
2. Grinding mill circuit Process Description A singlestage closed runofmine (ROM) ore milling circuit, as shown in Fig. 1, is considered in this study. The circuit consists of a semiautogenous (SAG) mill with an enddischarge grate, a sump and a hydrocyclone. The mill receives four streams as inputs: mined ore (MFO), water (MIW) to ...
Since model predictive control can address most of these difficulties quite well, it was decided to design and test a model predictive controller for a milling circuit. Model predictive control Model predictive control (MPC) uses a dynamic model of the plant to predict the future actions of the manipulated variables on the plant output.

In this article a robust MPC controller is presented for a runofmine milling circuit. The objective of the controller is to reduce the variability in the particle size from the milling circuit which leads to increased recovery of gold from downstream processes.
The mining industry has recently been looking at MPC technologies because economic pressures dictate that maximum value be extracted from their process equipment. The application of MPC to milling circuits poses a number of technical challenges. These challenges arise from the discrete events, nonlinearities and time
