Investigations were carried out in a laboratory ball mill having the size of DxL= 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 #177; 2 HRC according to Rockwell.

product size distribution for a ball mill. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser 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 cylindrical shell rotating about

Ball mill Wikipedia
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

Ball size distribution in tumbling mills is commonly used to optimally control the mill product size distribution leaving the mill. This is owing to the fact that each ball size effectively break a particular size range in the mill. The optimum ball size distribution is determined by the amount and combination of ball sizes in the makeup charge.
