OPTIMIZATION OF COMMINUTION CIRCUIT THROUGHPUT AND PRODUCT ...

    Apr 01, 2003 · 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 the product size distribution, so that the amount of excessively fine material produced can be minimized. The goal is to save energy by reducing the amount of material that is .
