Mill Process Grinding Mills. Grinding Mills also know as SemiAutogenous (SAG), Ball or Regrind Mills are used in the primary or early stages of pulverizing the ore in the process plant. This initial grind of the ore is typically completed in two or three stages.
The SAG mill product is then crushed to passing mm and is subjected to the Bond ball mill work index (S dBWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill
