The price is primarily driven by the belt width (typically 500mm to 2400mm), the tensile strength of the belt (ST steel cord vs. EP fabric), and the motor power requirements. For iron ore, which is high-density and abrasive, you must specify high-abrasion resistant covers (DIN X or W standards) and heavy-duty impact idlers. A conveyor designed for 1,000 tons per hour (TPH) will have a significantly higher price point due to the required reinforced steel structure and high-torque gearboxes compared to light-duty systems.
