### Attrition Mills - Powder Metallurgy - Beyond Discovery

Dec 13, 2020 For fine grinding, both impact and shearing forces must be present. In attrition mills, impaction is caused by constant impinging of the grinding medium, due to irregular movement. Shearing action is produced by random movement of the balls in different rotational directions, which exerts shearing forces on the adjacent slurry.
