Numeric Evaluation of Kinematic and Dynamic Characteristics of Mineral Treatment in Disintegrator

Abstract

The numerical modeling provides a holistic picture of mechanical treatment and activation of substances in a disintegrator. The authors calculate kinematic and dynamic characteristics of elastic and inelastic collisions in terms of halite, quartz and sulfur particles and disintegrator fingers. The recommendations on selecting optimal treatment conditions for natural minerals and waste material in order to dissociate mineral concretions and for selective activation of minerals are given. The research findings can partly be used for other types of percussion disintegrating devices, in particular, jet mills.
