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: ST1000,ST1250,ST1600,ST2000,ST2500,ST3150,ST3500,ST4000,ST4500,ST5000,ST5400.
1) Technical Data For Steel Cord Conveyor Belt According to DIN22131
Note: The length of single roll of conveyor belt is 100m-1500m, depending on its thickness, width, transportation and installation conditions. The length shall be determined through discussion of supplier and buyer.
