How to Measure the Impact Forces in Ball Mills

2019-1-16  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

Ball Milling - an overview ScienceDirect Topics

Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation. The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes.
