ATTRITORS AND BALL MILLS HOW THEY WORK …

The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run even faster rpm (1200-1800). Various types of Attritors fall in between these. ... The point at which the charge breaks away from the periphery of the mill as it is ...

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

How to Handle the Charge Volume of a Ball Mill or Rod Mill ...

In physics, the charge of a volume is commonly described by a quantity called the charge density or the charge distribution. When the electric field that arises from the charge distribution exhibits a volumetric symmetry, a handy relationship known as Gauss's Law may be used to calculate the charge distribution of the volume.
