Influence of Grinding Ball-Motion Behavior on Particle ...

A method of preparing micro-particles by changing ball-motion behavior in a flutter mill is proposed and multiple grinding experiments are conducted. Crushing performance parameters, such as breakage rate S i , production rates of fine particles F i and F i * , are studied in different motion conditions. From the results, a better crushing performance is attained in the coupled motion modes of rotating speed
