  • Mill (grinding) Wikipedia

    SAG is an acronym for semi-autogenous 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' (12.8m) in Optimizing your SAG mill operation International Mining,Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).SAG MILL DISCHARGE SCREENS-TROMMEL vs. ,grinding lines used both types of screens and on line two we used only a trommel.
