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 …

The dynamics of milling circuits, particularly those involving Semi-Autogenous Grinding
(SAG) mills, are not adequately studied, despite their critical importance in mineral …

The Appearance function, also known as breakage distribution function, is used to describe
the breakage characteristics of an ore impacted with a certain energy. It is the bedrock of …

Optimisation of grinding circuits is invariably dependent on sound process models together
with process simulators that can solve the process models accurately. Most of the process …

In order to develop a common mathematical and simulation platform for tumbling mills, a
review of existing mechanistic models was made identifying the key aspects of grinding and …

A mechanistic model for tumbling mills was developed based on breakage characteristics
and tumbling mill operational features. The concept was presented at the IMPC …

Grinding is one of the most energy-consuming processes in the mining industry. As a critical
part of the comminution process, autogenous grinding (AG) or semi-autogenous grinding …
