A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell''s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...

• Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of to 2 Mt/a.
SAG 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 of 8 to 21%. The largest SAG mill is 42'' () in diameter, powered by a 28 MW (38,000 HP) motor.

intermediate size ready for final grinding in a ball mill, pebble mill, or VERTIMILLTM. Wet grinding is accomplished in a slurry of 50 to 80 percent solids. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
mills in the older plants that had many mills in parallel. In fact this is generally still the case in the multistream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.

Today we will learn about difference between sag mill vs ball mill A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting
ball mill can be reorganised as [7] and [8], where B''Wio and A''Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the
SAG mill liner changeout life/cycle vs. tons/kg consumed. Ball mill liner efficiency based on liner geometry and its influence on kWhours/ton, total tons/life cycle, and P80 transfer to cyclones. Ball mill grind is based on different principle; it has some attributes similar to SAG mill optimization. SAG mill breaks with stirring the kidney ...
material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill .
This is because by definition overflow mills operate all of the time with a slurry pool. Some idea of how much slurry pooling in an extreme case can cause the power draw of an AG/SAG mill to drop can be gauged by switching the discharge mechanism choice in the model from grate to overflow when predicting the power draw of an AG/SAG mill.
