An Expert System for Control of a Sag/Ball Mill Circuit. Aug 01, 1992 It was initially developed for a SAG/ball mill grinding circuit on the gold plant at Paddy's Flat in Western Australia. The aim of the system is to provide a quick reference manual plus immediate on-line advisory help for the shift operators.

A flowsheet of the primary ball mill circuit is shown in Figure 1, indicating . the various control loops and process measurements available to be utilized by an expert system. The circuit consists of two identical . primary ball mills running in parallel with an overall processing capacity of 2500 TPD.

Precise control of SAG mill loading and flotation cell level is critical to maximize production and recovery in mineral concentrators. While expert systems are commonly used to optimize these process operations, the underlying regulatory control is often implemented using traditional proportional-integral­

Effective SAG mill control will maximise throughput, minimise damage to mill internals (liners and lifters) and contribute significantly to achieving maximum recovery in flotation. Well designed and implemented SAG control will payback in weeks not years. SAG mill control is essentially the stabilisation of mill load (and/or power) and density

the SAG mill feed stockpile before being fed to the SAG, Ball, Crushing (SABC) circuit. Ore is drawn from underneath the SAG mill feed stockpile onto the SAG mill feed conveyor belt by means of three vibrating feeders. The ore is fed into the SAG mill for primary grinding. The SAG mill discharge passes through a

INTRODUCTION First Quantum's Kansanshi Mine and the Advanced Systems Group of SGS collaborated on the implementation of an expert system for the control and optimisation of a SemiAutogenous (SAG) mill on the sulphide grinding circuit. The primary objective was to increase SAG mill stability and to maximise throughput.

An expert control system can deal with all kinds of quantitative or qualitative, precise or fuzzy information. It can select an open-looped or closed-looped control strategy according to the time-variability and uncertainty of the control object and the random interference. ...
