What Conveyor Dynamics does

Conveyor Dynamics, Inc. (CDI) is a privately held engineering consultancy founded in 1981 by Lawrence Nordell and headquartered in Bellingham, Washington, with a wholly-owned subsidiary in Lima, Peru. The firm specializes in the dynamic analysis, design, and control engineering of long-distance (>2 km), high-capacity (>10,000 tph) belt conveyors and transfer chute systems for the global mining, minerals processing, and bulk materials handling industries. CDI pioneered the application of computer-based dynamic analysis to conveyor belts and is credited with three world-record designs: the Impumelelo 26.8 km overland conveyor (2015, South Africa), the Curragh 20 km trough conveyor (2007, Australia), and the Yubei 15 km pipe conveyor (2017, China); the Los Pelambres downhill conveyor (25 MW regenerated power, Chile, 1999) holds the record for the highest-power downhill conveyor system.

CDI's core technology stack centers on proprietary engineering software — BeltStat (steady-state belt design), BeltFlex (dynamic starting/stopping simulation), and PStress (cloud-based pulley finite-element analysis) — combined with Discrete Element Modeling (Rocky DEM, LIGGGHTS) for chute geometry optimization, ANSYS FEA for structural analysis, and a proprietary rubber rheology model developed from field data starting in 1988 that underpins its Low Rolling Resistance belt design practice. The firm complements software with specialized hardware products, including the DEFT3a tachometer, Pan Rip Detector, Ninja Idler Change system, and a Holdback/Backstop Loadsharing device for high-power incline conveyors, and it operates high-speed data acquisition (64–1,000 Hz strain gauge instrumentation) for forensic root-cause analysis.

CDI generates revenue through five principal streams: (1) engineering consulting services for overland, pipe, and trough conveyors and control systems on a project basis; (2) software licenses and subscriptions for BeltStat and PStress; (3) hardware sales of proprietary instruments and tools; (4) forensic engineering and failure-investigation services; and (5) feasibility studies with CAPEX/OPEX estimation. Go-to-market is enterprise and relationship-driven, executed directly with mining majors, EPC contractors (ELB, Laing O'Rourke, Huadian Heavy Industries, Krupp JV) and OEMs (Double Arrow Rubber) across the Americas, Africa, Asia-Pacific, the Middle East and Europe, with flagship customers including Atlas Energy Solutions, Antofagasta Minerals, SASOL, Dangote Cement, Collahuasi, and Zimbabwe Iron and Steel.
