Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

A trunnion mill has the trunnion bearing supporting the entire weight of the mill. Changing out a trunnion rolling element (or sleeve) bearings requires the support an entire end of the mill. Specialize cradles and lifting gear is required. With a slipper pad bearing mill, the load is distributed via 4 (or more) pads per end.

things. It is incorrect to say, for example, "the ball mill work index is 13 kWh/t and the SAG mill SEC is 5 kWh/t, so the total circuit energy is 18 kWh/t." This example is a real discussion that one of the authors had with a flotation engineer who was confused because of the convention of using the same units for both quantities.
