Timing Effects on Fragmentation by Blasting
Relatively longer delays resulted in better fragmentation with more damage to the back of the blocks. The work continued to investigate the effect of blast gas on fragmentation by conducting similar tests in blocks but by placing copper pipes in the blast holes to control the gas propagation through the blast zone. Although gas penetration did not

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.
