The ball mill is rotated on its own axis at low speeds. The rotation of the mill imparts tumbling & cascading action to the balls fed (in this case the lead pellets). The rotation is adjusted so that the raw material inside does not reach critical speed. Below the critical speed (at around 65 75%), the balls which are carried along the wallsget price
