Key Performance Indicators of Conveyor Belts
2026-03-11
Tensile strength: reflects the belt’s resistance to rupture, expressed in N/mm (e.g., conventional canvas belts typically range from 100 to 300 N/mm, while steel-wire-rope-core belts can exceed 2,000 N/mm).
Abrasion resistance: Evaluated using the DIN abrasion test or the Akron abrasion test; the lower the value, the better the abrasion resistance.
Temperature resistance: Short-term temperature resistance can reach 200°C; for long-term use, the temperature must be kept within the material’s allowable range.
Flame retardancy: In coal mine and other similar environments, the product must comply with MT668 standard and exhibit self-extinguishing properties.
Splice strength: Mechanical splices (such as rivets and clinch fasteners) typically achieve 60–70% of the belt’s tensile strength, whereas vulcanized splices can attain over 90%.
