N2 - In order to address comminution efficiency,which could be defined as the increase in mass specificsurface against net specific energy input, the energy consumptionof an industrial mineral with and without preweakeningby high voltage pulses covering the same sizerange were compared. The three tested comminutionsequences consisted of a laboratory jaw crusher or pilotscale high voltage pulse machine at two different circulatingloads, a laboratory crusher and two tumbling millsof differing grinding media; all being operated followingthe principles of energy optimized comminution accordingto the OCS-method. The first results indicate that possibleenergy reduction by electrodynamic pre-weakening isavailable in the immediately subsequent, but not in furtherconventional comminution stages for the tested industrialmineral.
