Semi Autogenous Grinding Mill Used In Mineral Processing Plant

Mill (grinding) - Wikipedia

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rot…

SAG mills (semi-autogenous grinding mills) - Metso

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.

Grinding Mill - an overview | ScienceDirect Topics

The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).

Semi-Autogenous Grinding of Copper Ores

To date, the authors have been unable to draw a corresponding relationship between Bond Work Index and Operational Bond Work Index for semi-autogenous grinding plants. The inability to do so appears to be related to rock competency, i.e. the fact that the work index is not constant over the range of size reduction under consideration.
