  • SAG Mill Grinding Circuit Design911metallurgist

     · By combining with SAG discharge and screening on the SAG discharge screens top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling while convenient this has the disadvantage of not controlling the top size of feed to the ball-mill

    The ore is then ground into very fine particles less than one-fifth of one millimetre in diameter in large rotating SAG (Semi Autogenous Grinding) and Ball Mills which look like huge steel drums. Water is added to the process creating mud-like slurry which is pumped to large tanks called flotation cells.
