Autogenous and Semi-Autogenous Mills ScienceDirect

Jan 01, 2016The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.

Semi Autogenous Grinding Mill an overview

An autogenous mill of ID 6.7 m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20% of its volume. The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speed. The solids in the mill charge were at 80% solids. Estimate: 1. The power consumption per tonne per day. 2.

SAG Mill Autogenous and Semi-Autogenous Mills

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

What is the difference between a SAG mill and ball mill?

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.[8]
