A SAG Mill trommel screen lets you control the true discharge sie of your SAG mill or the transfer sie to the downstream Ball Mill circuit. A well sied trommel should not let rocks pass to the Ball Mill if they are to be more than say 58 or 16mm In the image case below strangely enough is the mill shell liner and discharge grate manufacturer

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 …

The mill's SAG/ball/flotation circuit was initially designed for 35,000 mt/d. As mentioned earlier, a secondary crushing circuit had been installed to boost the mill tonnage rate to 40,000 mt/d. However, the increased circulating load led to overloading of the original 12 x 28-ft single-deck SAG mill discharge screen.

The SAG mill discharge slurry will be combined with crushed pebbles and ball mill discharge in the cyclone feed pump box. The hydro cyclones will classify the solid particles by size. Particles that are fine enough will proceed to flotation while particles that are too coarse will be returned to the ball mill for further grinding.
