  • Tower Mill Operating Work Index

    The basic grinding action in the Tower Mill is abrasion. The absence of impact limits practical feed size to 5mm. Because there is greater pressure between media and less production of heat and sound, the device consumes less energy than a tumbling mill to perform the same work. The normal top size of balls in a Tower Mill is 25mm.
