Journal On Roll Mining Mill Mechanism Pdf

  • Hot Rolling Mill Hydraulic Gap Control (HGC) thickness

    On the unloaded mill there is no force before the slab or the strip arrives into the roll bite, therefore the gap has to be pre-set with an anticipated mill stretches. The anticipated mill stretch depends on the strip characteristics (size, material) and can be calculated using a high level system.

  • 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.
