Bucket Wheel Reclaimer Case Study using Rocky DEM

Bucket Wheel Reclaimer Case Study using Rocky DEM

Discrete Element Modelling (DEM) is a computational technique used to predict the flow of particles and its interaction with the surrounding environment. Rocky DEM is a high fidelity particle simulation computer program that is used across a wide range of industries to redesign, troubleshoot and optimise existing bulk flow systems.

In this presentation, a case study will be presented by Onyx Projects, based in Perth WA, who were contracted as part of a ports sustainability program targeted at reducing delays and improving operations overall.

A Bucket Wheel Reclaimer (BWR) chute experienced a significant number of stoppages due to belt drift and blockage/build-up issues reducing the availability of the fines ship loading circuit. Several investigations over the past 15 years failed to identify root causes and solutions to the problem.

Working closely with the client we (Onyx Projects) identified the previously un-identified underlying root cause for the belt drift delays and replicated these problems using Rocky DEM simulations, which had never previously been achieved.
