Effect of Spike Parameter Quadratic Fit on Wear in Excavator Bucket
Keywords:
Wear, Abrasion, Spike Parameter, HEMM.Abstract
The main purpose of this work is to identify the relation between particle shape parameter and complex wear mechanism that usually occurs in heavy earth moving machines (HEMM) used in open pit mines. In this work the wear phenomenon has been analyzed for the bottom plate of buckets used in excavators like shovel and dragline. Abrasive particles having different shape parameter present in earth material has been collected for measuring the shape parameter. An attempt has been made to evaluate the particle geometry by calculating its spike parameter quadratic fit, which indicates the value of the spikes present in the particle periphery. Particles having different spike parameter have been analyzed and noticed that the wear is varied with respect to the particle spike parameter.
