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' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.SAG Mill Grinding Circuit Design,Relative to other comminution machines in the primary role. SAG mill operation is more dynamic, and typically requires a higher degree of process control sophistication. Though more complex in AG/ SAG circuits relative to the crushing plants they have largely replaced, these issues are well understood in contemporary applications.Optimizing your SAG mill operation - International,Optimizing your SAG mill operation Posted by Matrix on 21st March 2007 Sanjeev Latchireddi, Chief Process Engineer – Grinding Americas, Outokumpu Technology, looks at the shift from ball mills to SAG mills.
