What Classifier Milling Systems does
Classifier Milling Systems Corporation (CMS), founded in 1994 and headquartered in Orangeville, Ontario, designs and manufactures industrial size-reduction milling systems for sale to enterprise customers globally. Its core technology is the Air Swept Classifier Mill, which combines impact grinding and air classification in a single continuous process with independent drives for the classifier wheel and impact rotor; the platform is offered from a portable 150-lb/hr Tabletop Lab System through production units from 5 HP to 600 HP. Complementary products include Hammer Mills (down to 45 µm D90), Pin Mills (down to ~10 µm), High-Efficiency Cyclones, Dust Collectors, the proprietary Quick Clean Rotary Airlock Valve, and Dry Sorbent Injection (DSI) Systems for power-plant air quality control. The company operates manufacturing in Canada and the Philippines, toll-processing facilities in West Virginia and Ohio, and sales/support offices in China and Singapore.
CMS operates a hybrid hardware-plus-services business model. Capital equipment is sold directly to industrial buyers (chemicals, powder coatings, food, minerals, air quality, pharma, battery/graphite) on a custom quote basis tied to specifications and horsepower. Recurring and adjacent revenue streams include White Label toll/contract processing from ACMS (Parkersburg, WV) and the CMS Marietta Division (OH), proprietary spare parts (classifier wheels, rotors, liners, hammers in stainless steel, ceramics, and tungsten carbide), and field services plus a certified two-day operator training program bundled with every equipment sale. Named enterprise customers include PPG, Babcock Power Environmental, Vesuvius Canada, and Carbon Graphite Materials (processing ~5,000 tons/year on CMS mills), supported by a sales-led, event-driven go-to-market with Thomasnet distribution and active participation at the International Powder & Bulk Solids Conference. The company is privately held under the Vanderhart family (Todd Vanderhart, President; David Vanderhart, Director of Operations), has never raised institutional capital, and has no disclosed revenue or headcount figures.
