feed size for sag mill

Mill (grinding) - Wikipedia

SAG is an acronym for Semi-Autogenous Grinding SAG mills are autogenous mills but 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% The largest SAG mill is 42' (128m) in diameter, powered by a 28 MW (38,000 HP) motor

(PDF) Influence of feed size on AG / SAG mill performance

The feed size distribution together with the ore characteristics (hardness, lithology, alterations, etc) are the most important factors affecting the SAG mills performance

or ‘Mine-to-Mill 20’ - srk

Feed size effects what size is important? historically, Mine-to-Mill has – focussed on blasting alone – generation of more fines • pass through SAG mill onto ball mill circuits • higher throughput (eg 10% to 30%) • coarser grind size (possibly) fine

Choosing a SAG Mill to Achieve Design Performance

SAG mill itself and not on the test work program Stated another way, money invested in a large SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rat

SAG Mill Grinding Circuit Design

The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chut And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media detritor (SMD)
