By rotation of the mill body, due to friction between mill wall and balls, the latter rise in the direction ofrotationtill a helix angle does not exceed the angle of repose, whereupon, the balls roll down.
ABall MillCritical Speed (actuallyball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at themillshell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside amillas speed varies. Use our online formula Themillspeed is typically defined as the percent of the Theoretical ...
In Grinding, selecting (calculate) the correct or optimumballsize that allows for the best and optimum/ideal or target grind size to be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, theballusedin ball millsis oversize “just in case”. Well, this safety factor can cost you much in recovery and/ormillliner wear and ...
SAGmilldischarge control is quite involved due to few interactive variables, such asmilldischarge sump level, classification hydro-cyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multi-inputmulti-output (MIMO) controller, is very suitable for this purpose.
