Application of a vision systems for assessment of particle size and shape for mineral crushing products

Morphological properties of mineral particles, in particular their size and shape, play a fundamental role in the course of mineral raw materials processing. They affect the efficiency of grain classification and downstream beneficiation operations. The article presents the results of the size and shape distribution for the particles after the comminution process. The measurements were made with using a vision system with dynamic image analysis. The aim of investigations was to evaluate the applicability of this technique for control of the particle size of raw material products crushed in various laboratory crushing devices. (paper)
