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.

Impact mill - Wikipedia

The other class of mills are "attrition" or grinding mills. Impact mills pulverize the material upon impact. The feasibility of impact mills was greatly enhanced by the mechanization and engineering of the Industrial Revolution. Prior to the industrial revolution, milling was primarily done by attrition or grinding the material between two surfaces. Attrition milling continues to be the dominant milling class, particularly in the milling of agricultural products (i.e. grain into flour). Roller mills and stone millsare two examples of attrition (grin
