A lining redesign (shell lifters, grate plates and pulp lifters) done at the Cortez Gold Mines (Crescent Valley, Nevada) SAG mill has produced a very definite reduction in power draft; it is estimated that the power decreases in the 230-370 kW range. Hence, energy consumption per ton of ore milled decreases by 0.3-1.3 kWh/t, in the 10% range.

SAG mill. 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.

The Extra Utilities 2 Crushers do cobble -> gravel and gravel -> sand at a 1:1 ratio. They can also be upgraded to be even faster than a SAG Mill. Another option would be to look at Chickens or Mystical Agriculture. Sand Chickens produce sand, and 2 fire and 2 dirt essence from Mystical Agriculture produce around 24-32 sand (not at my PC to check).

For example, Berezitovy’s SAG mill was stopped at 9 a.m one day for an inspection, and allowing for brief ventilation, two technicians then entered the mill. Wear on the metallic part of the lining was measured using an ultrasonic device, while the remaining thicknesses of the rubber/Poly-Met parts were measured with a special gauge.
