Technical Report: OPTIMIZATION OF COMMINUTION ...

Dec 01, 2001· The goal of this project is to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process are being used to study methods for optimizing he product size distribution, so that the amount of excessively fine material produced can be minimized.

Comminution, Part 1 — Steemit

Comminution is the process of transforming this large mixtured lump into its smaller valuable components and discarding of the impurities. Comminution works on the following principle: If energy is added to a large extracted particle, the outcome of this process will be the production of a smaller particle but also with the addition of sound as well as heat, to apply to the Law of Conservation of .
