MEI Blog: Where are SAG mills going?

Aug 25, 2014 . Interesting, as in a recent article in Mining Magazine (July/August 2014, pp. 27), Kurt O'Bryan of Weir Minerals says that, although SAG mills have been around for over 40 years, the demand to process more ore in less time is a key factor in where comminution trends are heading. He says that "SAG mills.

Model Predictive Control of SAG Mills and Flotation Circuits

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 derivative (PID).

ABSTRACT. Particle grinding is a key final stage in the comminution process used to liberate minerals from ga mineral processing plants. Semi-autogenous grinding (SAG) occurs in tumbling mills which use both large ore particles and steel balls as grinding media. Grinding is the most energy intensive of the mineral.

The sag mill serves in the line of industrial mining equipment designed to process, crush, separate, or locate precious metals from mined coal. The Sag mill is one of the large mining equipment pieces, and often requires mining equipment repair and maintenance. This is most often due to the large amount of heavy, residue.

SAG Mill Control: It Shouldnt be that Hard - WOMP

SAG milling is arguably the most commonly used method of comminution in mineral processing. So why are so many SAG mills operating sub-optimally and why are they considered to be so difficult to control? Operators often consider the basic controls provided during commissioning are as “good as it gets.” Those that do.
