Our experience started with the fitness evaluations of 28', 32', 36' SAG mills in the mid-1970s.

We diagnosed, repaired, redesigned, the 32' x 15.5' AG mills at Phalaborwa; the 28' x 12' SAG at Afton; the 36' x 15' AG mils at Hibbing Taconite; the 15.5' x 22' BMs at Cyprus Bagdad and numerous others.

Since then we have been involved in the design, fabrication, and various other aspects of many mills, including the FIRST 38' AG mill (at Olympic Dam); the FIRST 38' SAG mill (at Freeport Indonesia); the FIRST 40' SAG mill (at Cadia) and the FIRST 42' SAG mill (at Conga).
