A Study on the Effects of Ball Defects on the Fatigue Life

As a check for cleanliness, a clean swab with a spongy tip was moved across the surface of the ball. The surface of the ball was deemed clean when it felt like the ball was "grabbing" onto the moving swab. A final quick cleaning with a cotton/sponge swab removed any dust/lint that might have deposited in the contact zone. An aluminum block of a known mass was placed on top of the fixture

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
