A New Conceptual Model for Ball Milling - oatao

These quantitative measurements have been incorporated into a new conceptual model of the description of the ball mill. The model is based on identifying events that give rise to particle breakage, and using the fundamental experimental data obtained on the UFLC and other single-particle fracture tests, the probabilities of these events can be independently determined.
