Online servicesThe ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40,60, 80, 100, 150, 200 and300 ball millrevolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.
For this coarser feed the 50 + 20+10 mm ball diameter mixbreaks the material at a faster rate compared to the otherball matches. The availability of aball sizefor a particular feed size ensures breakage occurs at a faster rate. The 10mm ball sizeis unable to nip the largeparticle size…
