Perspective #139 – Some thoughts on Semi-Autogenous Grinding (SAG) Mills. Written by Richard Addison | Principal Process Engineer. This paper explores why SAG mills are an enigma when compared to ball mills, providing an in-depth analysis of how the advantages of SAG milling outweigh the shortcomings.

Comminution is a very important and result-determining step in mineral processing. This is because further downstream processes in the beneficiation chain depend entirely on it. Comminution includes the blasting, crushing, and grinding of ore to liberate valuable mineral particles. It consumes most of the energy used in mineral processing plants with …

 — Monitoring mill load is vital for the optimization and control of grinding process. This study proposed the use of an instrumented grinding media to assess solid loading inside a ball mill, with size and density of the instrumented ball comparable to that of the ordinary grinding media.

 — Grinding coarse ore in a ball-mill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tube-mill by 2- and 1½-inch balls or by flint pebbles or by hard, rounded mine rock such as quartzite. These grinding media wear to small sizes, and new ones must be added regularly to make up the weight.

 — What is Grinding Media? Grinding media are commonly used for the extraction of precious metals, when processing ore minerals. Grinding media are of two types-steel balls and grinding rods.The size of …

The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
