Optimization of primary gyratory crushing at Highland Valley Copper Rosario, Persio P.

Abstract

This thesis presents the work done in a collaborative research project between the University of British Columbia and Highland Valley Copper. The research was aimed at understanding gyratory crusher liner wear in the overall context of the crushing process. Wear measurements were taken for in-service crushers during the research period using a novel laser profile measurement device. Data from the wear measurements was correlated with crusher production information such as current draw and throughput. This work resulted in enhanced knowledge of crushing chamber characteristics and their impact on crushing performance. In addition, an innovative and powerful way to evaluate crusher liner profiles was developed and new mantle profiles were designed.
