Estimating excavator teeth consumption rates

Mining Engineering , 2010, Vol. 62, No. 8, pp. 45-51

Roos, C.J.; Conrad, P,W,; Rosenthal, S.D.


Ground-engaging tools are used to prevent damage to the main components of earth-moving equipment. These tools consist of everything from shovel teeth to replaceable drill bits to dozer wear plates. The costs of these “consumable” items are increasing with the costs of raw materials. This project developed a tool to be used by Newmont Mining Corp. to predict the consumption of excavator teeth at a particular mine site. This paper presents the results of the Montana Tech research project in which an equation was developed to predict excavator teeth consumption based on production rates and rock properties.
