effect of media size in ball mill dry grinding

An innovative approach for determining the grinding …

The dry grinding experiment was operated in the ball mill (Φ460 × 600 mm) with steel ball as grinding media at mill speed 47 r/min, space-filling factor φ 30%, and material ball ratio χ 0.6. The loading qualities of ore and steel ball were confirmed by eq. , .
