Mill (grinding)

SAG mills are autogenous mills but 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' () in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' () diameter and a power of 35 MW (47,000 HP) has been designed.

How to Calculate Tension in Physics: 8 Steps (with Pictures)

May 06, 2021 · Account for acceleration after defining the forces. Gravity isn't the only force that can affect the tension in a rope so can any force related to acceleration of an object the rope is attached to. If, for instance, a suspended object is being accelerated by a force on the rope or cable, the acceleration force (mass × acceleration) is added to the tension caused by the weight of the object.
