The Effect of Ball Size Diameter on Milling Performance OMICS

A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was determined that the 30 mm diameter balls were most effective of the three sizes during the grinding of the 3 monosize feed material samples. The 10 mm diameter balls were the least effective as minimum particle breakage was observed [//]A mill run having a mixture of the 3 ball diameter sizes was also conducted.

Ball 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 shell. A ball mill consists of a hollow [//]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.
