Abstract
Applications of the narrow-beam γ-ray method for dry grinding powder technology are discussed. In a model of a vertically agitated ball-mill, the spatial distribution of model milling charge with and without model grist and the spatial distribution of the grist were investigated. The model volume was 101. Polystyrene balls (diameter 4.5 mm) were used as a model of the milling charge and limestone—CaCO 3 of diameter 0.04–0.1 mm as a model of the grist. A system of mixing discs (10 rev s −1) on a coaxial shaft kept the mill-charge in vibrational motion. The results are presented in the form of graphs of the bulk density of the mill balls or the bulk density of the grist plotted against the height or distance from the stirred axis. The radionuclides 241Am and 137Cs were used as radiation sources.
