A sub-micron particle size down to 350 nm was achieved, while the grinding energy efficiency or enhanced grinding rate was shown to be improved with the addition of grinding aids and ...
Treatment of ever more lean and fine-grained ores has necessitated investigations of more efficient grinding methods in the - 50 /«m range. This paper reports our findings from using a stirred ball mill design and small grinding media, with excellent results in comparision with conventional tumbling ball mills. DENVER - SALA, S- 73325, Sala ...
fine grinding in stirred bead mills. The grinding mechanism occurs due to fine particles being trapped and stressed between moving beads which are accelerated by the agitator and collide or rub against each other. The efficiency and the grinding rate depend on several variables such as the agitator speed and the size of the grinding beads.
