Size distribution analysis of wear particles in the transmission system of mining equipment

In this work, size and shape characteristics of wear debris particles present in the transmission system of heavy earth moving machines have been analysed. Four oil samples were collected from the dumper transmission system for wear debris analysis. Ferrogram maker has been used to seperate the wear particles present in oil samples and to capture the image of particles. The statistical results confirm that the Weibull probability distribution function has more potential to fit the wear particle size distribution accurately than the Rayleigh model in case of heavy earth moving machines. Results show the initiation of abnormal wears and suggested that condition-based maintenance is necessary.
