Autogenous and Semi-Autogenous Mills - ScienceDirect
01-01-2016· Mills that grind hard ores with fracture characteristics that do not lend themselves to fully autogenous milling are charged with a small amount of steel balls to assist in the size reduction. These are known as semi-autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use.SAG Mill | Autogenous and Semi-Autogenous Mills | FLSmidth,Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. 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,SAM autogenious and semi-autogenious mills · Christian,,Our robust autogenous and semi-autogenous mills ensure efficient self-comminution of the product within the mill. In many cases, a SAM mill can replace a high-maintenance combination of crushing and screening equipment, making it a reliable, cost-effective alternative.Autogenous Grinding & Semi Autogenous Grinding Circuits,20-07-2017· An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. In this type of circuit, the ore must be competent so large chunks of ore can be used to grind smaller chunks of ore. https://www.911metallurgist/equipment/autogenous-mill/Semi Autogenous Grinding Mill - an overview,,Autogenous and Semi-Autogenous Mills A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 9.1 In a SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9 respectively.SAG mills (semi-autogenous grinding mills) - Metso Outotec,Semi-autogenous Metso Outotec 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.
