A probabilistic particle replacement model to simulate bulk material degradation during conveying processes using DEM

Hoisting and Conveying Equipment and Technologies

Due to mechanical stress during transport and storage, bulk material partly degrades and fines are produced. This can be problematic in various applications and is often responsible for high costs, energy consumption and emissions. In this work a model for the discrete element method is presented to simulate particle breakage during conveying processes. The breakage model is based on the particle replacement method. In contrast to other particle replacement models, mass and volume remain constant. The model has been verified and validated by a trial of shatter tests with blast furnace sinter. High mass flows and further breakage of fragments can also be simulated. An application of this model is presented, where two different transfer chutes are compared with regard to material degradation. Simulation and test results are consistent.

Host city and venue - Belgrade

Belgrade is the capital and largest city of Serbia and a city of very tumultuous history. Belgrade was the capital of Yugoslavia from 1918 to 1991. It is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. It is one of the oldest cities in Europe and since ancient times it has been an important traffic focal point, an intersection of the roads of Eastern and Western Europe. Read more...
