Mining Operation Conveyor Chute Optimization Benefits from DEM Investigation Insight

A mining operation diligently considered input parameters and material test options to glean particle-flow results that could be trusted.

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.

This paper includes:

  • Description of Peñasquito mine’s existing overland conveying system
  • The case for using DEM
  • Material test work and calibration
  • Best practices for accurate results: identifying input parameters and conducting material testing
  • Detailed analysis of material blends for four conveyor transfer points
