Discrete Element Method Modelling Of Liner Wear In Dry

This paper explores the prediction of the liner wear using the discrete element method (DEM). A mathematical model taking into account adhesion, abrasion and impact wear which occur in dry mills is derived in order to predict the loss of material on liners.

Discrete element method (DEM) modelling of evolving mill

01/12/2005· In this paper, we use the discrete element method (DEM) to simulate the load behaviour and predict the wear of two different liners used in industrial mills for the grinding of coal in dry conditions. Our simulated results are compared to industrial measurements in both cases. A good agreement is found between those measurements. Moreover a quick empirical equation is derived for

DEM modelling of liner evolution and its influence on

Wear of grinding mill liners and lifters plays a major role in the overall efficiency and economics of mineral processing. Change in the shape of lifters as they wear has a significant influence on grinding efficiency, and the annual cost of maintenance and mill down-time depends on the life of both liners and lifters. The Discrete Element Method (DEM) is a computational method for simulating
