Is it possible to use balls (that used in bearings) for ball milling?

It is advisable to determine the chemical composition, grain size, hardness and abrasive indices of the ball bearings before using. Usually balls for the ball mills are chromium-base alloy steels foundry-cast, some times aluminum oxide balls. The angle of inclination of the ball mill unit, rate of rotation and time for the rotation.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and blend 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.
