2018-4-18 A recent calculation on a 30′ diameter, 7000 Hp, semi-autogenous mill indicated that a flat end vs. conical end construction would require a shell weighing 13% more to account for stress alone. Deflection was still better in the conical-ended mill as opposed to the flat-ended mill.

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).
