According to the structure: common type and impact-resistant, tear-resistant type.
According to the purpose: ordinary type, wear-resistant, heat-resistant, cold-resistant, acid-alkali-resistant, flame-retardant, tear-resistant, flame-retardant, ozone-resistant and other types.
Heavy duty 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.
It is composed of upper coating layer, lower coating layer, steel wire rope, adhesive layer and side glue.
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 cord rope, even tension of steel cord rope, good slotting performance, etc. It is suitable for conveying massive, granular and powdery materials in high-strength, long-distance and large traffic situations.
