For relevant industries and applications, DEM is a proven tool for modeling the interaction between individual particles and boundary surfaces. The technique can be leveraged to optimize equipment, thus improving process efficiency and product quality — while reducing design and operating costs.
In this application, mining industry researchers applied DEM to learn more about particle-flow dynamics in conveyor chute equipment. The engineering team used best-practice techniques to accurately predict bulk materials behavior — which cannot be observed nor incorporated into prototype testing. Researchers worked diligently to ensure that they used proper inputs, thus ruling out imprecise solutions.
