Grinding media shape: cylpebs versus ballsgrinding charge may be steel rods, balls, hard rock or in some cases, the ore itself. Grinding rods and balls have traditionally been used as grinding charge in the mineral processing industry for many years. In the recent years, in an attempt to increase grinding efficiency, cylpebs instead of balls have been developed.grinding media charge handling,Ball Charge and Grinding Efficiency - Grinding & Classification .Apr 4, 2017 . What I don't know is what happens to grinding efficiency as ball charge % filling is lowered. .. Obviously there are numerous potential inaccuracies and uncertainties associated with commercial mineral processing operations and a handful of case studies with conflicting conclusions is not a convincing.
