For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Two types of mills commonly found in the minerals pro-cessing industry are ball and semi-autogenous (SAG) mills, which use both ore and steel balls as grinding media (Wei and Craig, 2009b). In the case of a ball mill the ore is crushed before it enters the mill, whereas a SAG mill re-ceives run-of-mine (ROM) ore directly (Stanley, 1987). A
1. Introduction1.1. Background. With the continual depletion of high grade simple ore bodies, more complex, finely disseminated ore bodies are being processed, which has led to an increase in the prevalence of fine grinding (Sinnott et al., 2006).This has been evident in the platinum group element (PGE) industry in South Africa, where …
b. Autogenous and Semi-Autogenous Mills: In some cases, autogenous (AG) and semi-autogenous (SAG) mills are used for grinding. These mills utilize the ore itself as the grinding media, reducing the need for additional grinding media. AG/SAG mills are typically used for coarse grinding, where large pieces of ore are efficiently …
