Cliff Rasch

Mechanical Engineer, Principal Emeritus

Cliff enjoys hunting, fishing, and the great outdoors.

With a degree in mechanical engineering and over 46 years as a principal in charge, project manager, and chief engineer, Cliff has designed systems for materials handling, processing, piping, hydraulics, HVAC, dust collection, pollution control, and industrial ventilation.

Although he only considered a career in mechanical engineering because his father suggested it, Cliff took to it the way he took to football – with vigor and enthusiasm. After playing football at Hibbing Junior College for two years and making the Junior College All-American team, Cliff was recruited by The University of North Dakota where he earned a degree in mechanical engineering.

A stint at a large firm in Alabama where the engineers worked in just one area helped convince Cliff to return to Minnesota and a firm where he could work in a variety of areas and industries.

Over the years, he has worked on several notable projects for the mining industry, including designing a fine-screen oversize-grinding system that incorporated a cyclone cluster and the first vertimill installation in the US. Cliff managed the addition of a $28 million wet scrubber to reduce emissions from waste-gas discharge stacks at an iron-ore pellet plant. He also worked on the first commercial wet-scrubber installation at a US power plant to help meet its environmental permit requirements.

One of his most memorable projects was an innovative ship-loading upgrade that enabled taconite pellets to be loaded into ships over 1,000 feet long, doubling the dock’s live-load capacity and cut ship-loading time by more than half. The project was named one of the “Seven Wonders of Engineering” by the Minnesota Society of Professional Engineers.
