Ball mill - Wikipedia
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 axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.

Working Principle of Bead mill
The necessary energy for dispersion and grinding is transmitted to the grinding beads by the agitator discs. The mill is fed continuously by the pump. The time spent by the material inside the chamber is controlled by variation of the pump speed. The retention of the grinding beads inside the chamber is achieved by means of a cartridge.
