Abstract This paper addresses issues relating to the modeling and control of grinding mill circuits as used in minerals processing, with a particular emphasis on semi autogenous grinding or SAG mills. SAG mill circuits are generally difficult to control due to the presence of strong external disturbances, poor process models and the unavailability of important process variable measurements.

MILL CONTROL GENERAL CONCEPTS The problem of designing controllers for efficient control of grinding mills has been studied in the literature, but has not seen significant application in actual mineral processing plants Jerez et al 1985, Ciprano et al 1989, Rajamani et al 1991. The first successfully implemented multivariable process control
Controlled, high energy grinding with integral particle size classification result into ultra-fine grinding capabilities and a greater control over particle size distribution with the PPS Air Classifier Mill. This tight control of the particle size is achieved by the fully adjustable rotor speed, airflow rate, feed rate, and classifier speed. The optional clam shell body design facilitates easy access for inspection, maintenance, and cleaning processes. Controlled
The Control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was - incorporate an additional loop whereby mill speed is automatically adjusted to control mill weightload.
However, there have been numerous documented applications of advanced process control on pilot plants and industrial grinding mill circuits indicating the advantages of advanced process control. Hulbert 1983 used Inverse Nyquist array techniques to design a multivariable controller for a pilot grinding mill circuit.
The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
