Development of wear model for cone crushers
Journal article, 2006
Cone crushers are used in the aggregates and mining industries to crush rock material. A model to predict the worn geometry of cone crushers was previously developed. In that model there was some disagreements between predicted and measured geometry and several effects were suggested to explain the discrepancy in the model. In this study the effect of shear forces along the crushing surfaces was implemented in the model. Simulations were compared to measurements on two different crushing chambers. The results show a significant improvement with respect to the discrepancy between measured and simulated geometry. Measurements were made on a coarse crushing chamber where the operating parameters hydroset pressure, power draw and capacity were tracked during the lifetime of the set of liners. The simulated operating parameters show some agreement with measured data, but the crusher was not run under ideal conditions at all times. © 2005 Elsevier B.V. All rights reserved.
