Autogenous Grinding & Semi Autogenous Grinding

2017-7-20 · 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.

Semi Autogenous Grinding Mill an overview

Size reduction occurs through a primary crusher followed by semi-autogenous grinding (SAG). Large rocks are screened from the overflow and are sent through a pebble crusher, which recirculates the ore back to the SAG mill. The smaller material after SAG milling is classified by hydrocycloning.

Autogenous and Semi-Autogenous Mills FLSmidth

Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills 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

Autogenous Grinding Mining Fundamentals

2019-2-18 · In some applications that require the grinding of minerals, such as talc, asbestos, and mica, dry semi-autogenous milling is the preferred choice. Grinding is easily enabled in autogenous mills by attrition. Also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles.
