How to Measure the Impact Forces in Ball Mills

Jan 16, 2019 The ball was placed and recovered in the feed end of the mill where impact is known to be less severe. Analysis of ball movement in mills of various size and speed can use these rather basic data to estimate relative impact severity in other mills. Ball impact velocity depends on distance balls drop and horizontal component of peripheral velocity.
