A New Conceptual Model for Ball Milling AusIMM
These quantitative measurements have been incorporated into a new conceptual model for the description of the ball mill. The model is based on identifying all events that give rise to particle breakage, and using the fundamental experimental data obtained on the UFLC and other singleparticle fracture tests, the probabilities of these events can be independently determined.

In summary, ball‐milling has been used as a technique to conduct NHC catalysis for the first time. A range of catalysts, bases and grinding auxiliaries have been screened to reach general conditions for the acyl anion activation mode, which has been demonstrated in four application areas: intermolecular‐benzoin, intramolecular‐benzoin, intermolecular‐Stetter and intramolecular‐Stetter.

Ball mill Wikipedia
A ball mill is a type of grinder used to grind or 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 cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls
