  • 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.

  • Three roll mill Wikipedia

    The single-roll mill works by material passing between the roll and a fixed bar pressing against the roll. The five-roll mill incorporates four successively smaller in-running nips and hence, compared to the three-roll mill, allows the use of larger agglomerates as part of the input material- but is correspondingly more complicated and
