single SAG mill, a two stage grinding circuit is recommended. 4 ... Siddall (2004) showed the spread of impact energies derived from laboratory testing, and related these to the breakage energies present in a mill. Increasing the mill speed leads to an increase in breakage energy. If this is insufficient, then limitation of the feed size by

Laboratory Ore Comminution Tests - SMC Testing

Hence in this particular example, as Bond crushing and ball mill work index tests cannot be used to size SAG mill and HPGR circuits the project cannot be carried out and the ore charcaterisation programme has to be re-done with more appropriate choices of tests. 2. Can the chosen ore comminution test(s) be used with the available sample?

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 diameter, powered by a 28 MW (38,000 HP) motor.

Grinding Circuit - an overview | ScienceDirect Topics

A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al. [6] is shown in Figure 9.6, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.
