    The pilot mill is also equipped with a sensor measuring the ball and pulp toe and shoulder angles (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73 solids as the total media angle does not change.

    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.
