Effect of mill type on the size reduction and phase

A significant loss of surface area from 1366 m 2 /g to 826 m 2 /g is evident in the planetary ball mill samples, rendering the planetary ball mill as less suitable for size reduction of catalyst supportsBall mill - Wikipedia,A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shellSIZE REDUCTION AND SIZE SEPARATION,At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition between the balls Generally it is 05 cycles per seconds (cps)
