Ball Mill Grinding William Boulton. Ball Mill grinders are designed to reduce materials down to a fine powder, using the impact and friction created by a large quantity of balls – generally made from steel, but also available in other materials for specific appliions – which are placed inside a rotating mill to create a cascading effect.
