Particle Size Distribution of Grinding Mill Products
Apr 27, 2019 The 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 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.

Improving particle size distribution and flow properties ...
Sep 17, 2013 Chocolate mass is produced by roller refining and conching or alternatively by ball milling. Grinding can generate varying particle size distributions (PSD), which again influence flow parameters. The latter are very important for downstream processing as well as mouthfeel and consumer acceptance of the final product. The objective of the work was to influence and control PSD and flow ...
