In the simulation work, the effect of the direction of the rotation of a pot to that of disk revolution and rotation-to-revolution speed ratio, r (=N p /N r, N p: rotation speed of the pot, N r: revolution speed of the disk) on the specific impact energy of balls was investigated. Fig. 1 shows the schematic diagram of the planetary ball mill.

Milling method uses ball mill, rod mill, impact mill, etc to produce powders of required grade and fineness. If speed of rotation is low, it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high, the balls cling to the drum walls due to centrifugal force.

critical rotational speed ball mill

Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

2018-7-28 · When the rotation speed exceeds a certain limit to the high direction, by then, the steel balls will rotate along with ceramic ball mill cylinder without falling, at a centrifugal state. When the balls have no impact effect, with a very slight ore grinding effect, and ore grinding operation stops.

2020-3-25 · The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotat. ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and don’t fall.

2016-11-18 · Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.
