Conveyor Dynamics, Inc. (CDI) has the experience and technology to ensure your mass flow in your transfer chutes and hoppers while minimizing liner and conveyor belt wear. Our team stands ready to redesign your existing chutes and hoppers to eliminate plugging and/or funnel flow while minimizing liner and belt wear.
We use Rocky DEM and LIGGGHTS DEM software to evaluate and optimize conveyor transfer designs. Rocky DEM was originally developed at CDI but now part of ANSYS. When non-round particle geometries are important in the system, we model the system with the version of Rocky owned by CDI before Rocky spun off. Even today, the non-round algorithm in that version of Rocky is still the gold-standard unmatched in any other commercial DEM product.
LIGGGHTS is free open source software and is slower than Rocky but includes several useful particle to particle interaction models that were not part of Rocky at the time of the spin off. We use LIGGGHTS in special cases when these interaction models are relevant to the problem at hand.
These tools, combined with a proven method of material calibration, allow CDI to design low maintenance chutes for a wide variety of materials, including sticky materials such as clay fines combined with moisture.
The following case studies show how CDI used DEM to solve real chute design problems:
If your engineering group is interested in exploring open source free DEM software, our engineers can show your team how to use LIGGGHTS.
