Difference Between Sag Mill vs Ball Mill Mech4study
Ball mill is a fine grinder A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel The ball charge of a SAG mill is about 29% to 30% BySAG is an acronym for semiautogenous 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 ofWhat is the difference between a SAG mill and ball mill?

The power the mill consumes is a function of the ore and/or ball charge geometry and the mill speed The motor only supplies the amount of power (or torque really) that the mill demands, and we add some extra power to the motor to deal with 'upset' conditions like a change in ore density or a surge in ore level inside the millof trommel screens for 38’ to 40’ SAG mills that required 500 to 600 mmhigh weir bars to create sufficient retention time Super Scroll Whereas the scrolls on ball mills are cast onto the screen panel, the arduous duty associated with SAG mills requires scrolls to be bolted directly to the steel support frameSAG Mill Trommel Screens Multotec

* Semiautogenous (SAG) grinding is a grinding process carried out with small amount of ball charge (415%) unlike ball mills and with the help of bigger parts crumbling the smaller parts of ore * To achieve this type of grinding, SAG mills with large diameter and short length have been developed to take advantage of the kinetic energy of the free fallingBall mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% 40% of mill chamber volume To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill’s contents SAG mills generate higher levels of impact reduction andKey considerations when selecting a mill lining system | Weir
