Another factor in good ball mill design is the relationship between Bond Wi on crushed ore vs SAG ground ore. The latter measurement is required because the ball mills in SAG plants grind SAG discharge material and the grinding test should mirror the plant flowsheet. The SAG ground Wi is about 1 unit higher than a crushed Wi.
