Conveyor Equipment Manufacturers Association — the principal North American trade organization that publishes engineering standards, design guides, and safety recommendations for belt conveyors, screw conveyors, bucket elevators, and related bulk material handling equipment. Its cornerstone publication, "Belt Conveyors for Bulk Materials" (currently 7th Edition), is the industry bible for conveyor design in the Americas, covering: belt tension calculations, idler selection and spacing, drive engineering, material flow, loading and transfer point design, and belt selection. CEMA also publishes standards for idler classes (B, C, D, E) defining load ratings and life expectancy, and for pulley dimensions. Widely referenced alongside DIN 22101 (German standard) and ISO 5048 for international conveyor design. Membership includes major conveyor manufacturers: Martin Engineering, Flexco, Rulmeca, Continental, and others. For LATAM projects, both CEMA and DIN methodologies are commonly used.
