How an issue with SAG mill dischargers become a nine-year-and-counting collaboration. 3 January 2021. With its two SAG mills suffering a range of performance issues, a polymetallic mine in Mexico invited us in to assess the situation. Nine years later and our partnership with the mine had yielded a range of solutions that have significantly ...
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).
mill, and there is nothing to prevent a 1:1 aspect ratio mill of, say 10 m dia. x 10 m EGL equipped with a 20 MW motor from being fabricated. Such a mill would have a less arduous environment than, say, a 13.4 m (44-ft) diameter mill. Slurry transport issues then dominate the mill selection, rather than mechanical/structural constraints.
