An application of breakage mechanics for predicting energy

The approach is based on a breakage mechanics model that accounts for the evolution of the grain size distribution (GSD) due to comminution with only five parameters, all of which are physically meaningful. The model is implemented and used in finite element analysis to study the energy–size reduction relationship in a roller mill.

Powder Handling: Size Up Size Reduction

Aug 14, 2021There are three basic types of size reduction: 1. Crushing, in which material usually is forced between two machine elements; 2. Impaction, in which equipment components or an outside force hit the material; and. 3. Attrition or grinding, in which rubbing or friction reduces material size. Fineness is an indicator of the quality of the mill or
