A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 cylindrical shell rotating about its

When the rotating speed of the ball mill equipment is low, the medium is dominated by the falling motion, and the impact effect is small. The grinding effect is mainly grinding. The grinding machine has a low production capacity and is suitable for fine grinding.When the rotating speed is high, the proportion of the medium dropping motion mode increases, and the impact effect is strong.

Critical Rotating Speed Of A Mill Arctechnologies. Critical rotational speed nc of ball mill.Where nc is the critical speed of the mill in revolutions per minute and d speed.Evidence guide.1. Live Chat; Critical Speed Of The Ball Mill Nc In Powder Metallurgy

The critical speed of a rotating mill is the RPM at which a grinding medium will begin to "centrifuge", namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed.

When the rotating speed of ball mill exceeds a certain speed, the steel ball will rotate with the barrel and won't fall down, in a condition of centrifugal movement. There is no impact force, so the grinding function is much less, and the ball mill stop grinding. So in the production of ball mill, to control the critical rotating speed reasonably can realize the effective control on the
