· Conveyor belts resemble a band or loop of rollers connected to rotors powered by a motor. The belts can be as narrow as one inch (25 mm) or as wide as five feet (1.5 m), with plastic modular belts as wide as ten feet (3 m). Conveyor belts are made of highly durable and sturdy materials, much like heavy-duty machinery.
