Specializing in Conveyor Belts & Timing Belts to Help Keep Your Production Running Smooth.
 |
Purpose:
General purpose steel cord conveyor belt is widely used in coal, mine, port, metallurgy, electric power, chemical industry and other fields. It is suitable for conveying massive, granular and powder materials in high-strength, long-distance and large volume situations.
Structure:
General purpose steel cord conveyor belt is composed of upper covering layer, lower covering layer, steel wire rope, adhesive layer and side glue.
Features:
This product has the characteristics of high tensile strength, impact resistance, good elasticity, high wear resistance, small use elongation, good adhesion between rubber and steel wire rope, even tension of steel wire rope, good slotting performance, etc. it is suitable for conveying massive, granular and powdery materials in high-strength, long-distance and large traffic situations.
Executive standard: GB / t9770-2013 steel cord conveyor belt for general use
Main technical indicators:
Band strength | tensile strength （N/mm） | A wire rope （mm） | A wire rope （mm） | A wire rope （kN） | Overburden （mm） | Adhesion strength of steel wire rope ≥ | |
