Manufacturing Process of Heavy Duty Conveyor Belts The production of a robust heavy duty conveyor belt , particularly specialized types like the Large Angle Corrugated Edge Conveyor Belt, involves a meticulous, multi-stage process to ensure superior performance and longevity. This process adheres to stringent quality control and international standards such as ISO 9001 for quality management and relevant ANSI standards for material handling equipment. Key Process Steps: Raw Material Selection: High-grade rubber compounds (e.g., SBR, NBR, EPDM for specific resistance to abrasion, oil, or heat), high-strength synthetic fabrics (polyester, nylon, or aramid for textile belts), or steel cords (for steel cord belts) are selected based on the belt's intended application and operational stresses. For corrugated edge belts, specialized rubber compounds are chosen for flexibility and durability of the sidewalls and cleats. Fabric Preparation/Steel Cord Assembly: Textile plies are calendared with rubber. For steel cord belts, individual steel cords are precisely arranged and embedded within a rubber matrix, ensuring optimal tensile strength and load distribution. Compounding and Extrusion: Rubber compounds are carefully mixed with additives to achieve desired properties (e.g., tear resistance, flame retardation, weather resistance). The prepared rubber is then extruded or calendared into sheets for the cover and bottom layers. Ply Layup and Assembly: Multiple fabric plies (or the steel cord carcass) are layered together, with rubber layers in between, to form the belt carcass. For corrugated edge belts, the flat base belt is then prepared for the attachment of sidewalls and cleats. Sidewall and Cleat Forming & Attachment (for Large Angle Corrugated Edge Belts): Special extrusion and molding processes create the flexible corrugated sidewalls and various cleat profiles (e.g., T-type, C-type). These components are then precisely bonded to the base belt using advanced vulcanization techniques, ensuring a seamless and extremely strong connection capable of withstanding high tension and impact. Vulcanization: The entire assembly is placed into a large vulcanization press, where it undergoes heat and pressure treatment. This chemical process cross-links the rubber polymers, giving the belt its final elastic properties, strength, and durability. Finishing and Quality Control: After vulcanization, the belt is trimmed, inspected for any defects, and dimensional checks are performed. Rigorous testing for tensile strength, adhesion between plies, abrasion resistance, and flexibility ensures compliance with specified parameters and international standards. ISO 283 for textile conveyor belts and ISO 15236 for steel cord belts are commonly referenced. The average service life for a well-maintained heavy duty conveyor belt can range from 5 to 15 years, depending on the application severity, material conveyed, and operational environment. Target industries for such robust belts include mining (coal, ore, aggregates), quarrying, cement plants, steel mills, power generation, chemical processing, and port handling terminals. Advantages in these scenarios include energy saving through optimized material flow, superior corrosion resistance in harsh chemical environments, and significantly reduced material spillage.
