Dynamic modelling and simulation of semi-autogenous mills

A semi-autogenous (SAG) or autogenous mills (AG) circuit commonly comprises a pebble (cone) crusher to deal with the critical size particles. The pebbles crusher is often oversized, and thus not fully utilized. The hypothesis put forward in this paper is that active control of the cone crusher's eccentric speed and closed side setting …

SAG Mill Grinding Circuit Design

SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore …

Wear and Failure Analysis of Semi-Autogenous Grinding …

Grinding is one of the most important and expensive steps of mineral processing. Therefore, different types of grinding mills such as rod mills, ball mills, semi-autogenous (SAG) mills and autogenous (AG) mills can be utilized for comminution of mineral ores [].Up to today, SAG mills and AG mills have been widely used to reduce …

Model predictive control of semiautogenous mills (sag)

Among the different grinding processes, Autogenous (AG) and Semi-Autogenous (SAG) mills are widely used for ore size reduction. The main difference between these two mills is the use of steel balls as grinding media, typically in the order of 6–12% in volume (Sbarbaro et al., 2005), in the SAG mills.
