Keys to best practice comminution
When the author ran the 5.5 ft (168 cm) diameter Pilot Plant SAG mill for Art MacPherson's new SAG mill design projects in 1964–1965, the standard loading was "2 in. (51 mm) below the lip of the feed trunnion", or 26% load (Rexnord, 1976). It was known then to be the best and proper load at which to run a SAG mill and this has ...
