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.
Main technical indicators:
Band strength level | tensile strength (N/mm) | A wire rope spacing (mm) | A wire rope diameter (mm) | A wire rope Minimum breaking force (kN) | Overburden Minimum thickness (mm) | Adhesion strength of steel wire rope ≥ |
