The ball mill is powered by a fairly robust 12v dc motor salvaged from a junked printer it had a pulley for a finetoothed belt on it that should also help improve the grinding action as the steel balls bash against the hard walls of the pipe if i switch to a steel or iron container which would be heavier i might also have to beef up
The grinding principle of the rotary ball mill is different from that of the vibration ball mill which uses the highfrequency vibration of the cylinder to grind the materials and it is also different from the attritor ball mill which uses the agitator to stir the grinding media to grind the materials the rotary ball mill uses the rotary motion of the cylinder to drive the grinding steel
The operating principle of the ball mill consists of following steps in a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls then discharge of ground material performed
