Tower Mill Operating Work Index

The principal method of grinding in a Tower mill is attrition (scrubbing of particles off material being ground), with the possibility of some shearing and compression breakage taking place due to the motion of the media charge created by the rotation of the helical screw enhancing the media pressure. The Tower mill is filled to a level with grinding media until developed power
