A three roll mill is composed of three horizontally positioned rolls rotating in opposite directions and at differentSimulation of ball charge and liner wear - ScienceDirect,The ball charge wear model incorporates adhesive and abrasive wear as a function of energy dissipated in crushing, tumbling and grinding zones of the charge motion profile. The liner wear model incorporates abrasive wear with centrifugal and gravitational forces acting on mill liners.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.
