Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

More### Autogenous and Semiautogenous Grinding Practices

An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. Generally, for this type of circuit, the ore must be competent so large ore chunks can be used to grind smaller ones. If ore alone is used, then the circuit is autogenous; but if balls are added to supplement the charge, then the circuit is termed semiautogenous. Ore competency

Autogenous and Semiautogenous Grinding Practices. Autogenous and semiautogenous mills have been very successful on relatively soft uranium ores where the values are frequently found in the material that cements together the sandstone grains. Autogenous Circuits When an ore is hard and competent, it is always possible it might make good "pebbles" that could be used for fine grinding media. Semi

Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge.

01/01/2016· It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semi-autogenous operation with about 8% ball charge was the preferred option. Based on these test results, a 6.7 m diameter × 2.1 m length SAG mill and a 3.3 m × 6.1 m ball mill were installed for commercial operation in closed circuit with a hydrocyclone. The SAG mill had a 6–8%

The difference is that the barrel body of efficient autogenous mill is larger, which does not use steel ball or any other grinding medium. The efficient autogenous mill uses the crushed material in the barrel body as the grinding medium, which continuously impacts and grinding to achieve the purpose of grinding.
