Abstract The discrete element method (DEM) has been implemented to model abrasive wear on steel plates that interact with bulk solids, such as crushed copper ore. The Archard model was used to predict the rate and the wear pattern on a structural steel plate A37-24 ES under different types of copper ore. One of the key steps of the methodology consists of the proper characterization of the granular medium to calibrate the numerical model. The numerical results obtained are in good agreement with the values of the standard test method for measuring abrasion using the wear wheel (ASTM G65). This allows to establish that the model is able to correctly predict the phenomenon of abrasion wear. There are many processes where wear limits the life of equipment, affecting its productivity and operating costs. A numerical method such as the one developed here could be used to reduce costs in the design and operation of mining equipment, looking for configurations appropriate to the actual working conditions.
