Steel Cord Conveyor Belt

Standards: GB9770-88, MT147, MT668, DIN22131, JISK6369, AS1333 etc. Structure: The belt core is comprised of longitudinally and evenly arranged non-spinning galvanized wire ropes and high adhesive core rubber, with the upper side and lower side covered with rubber layer.
Features: High tensile strength, long service life, short elongation under service, good groove formation property and good anti-flexure property, suitable for conveying materials across long distance, with large volume and high speed.
Types: According to structure: General type, Impact resistance and Rip resistance transverse type. According to application: besides General-used steel cord belt, there are some kinds of Fire-retardant type, Cold-resistant type, Wear-resistant type, Heat-resistant type, Acid and alkaline resistant type, Oil-resistant type, High-grade type and etc.
Model: ST630, ST800, ST1000, ST1250, ST1600, ST2000, ST2500, ST3150, ST3500, ST4000, ST4500, ST5000, ST5400.
