ST CONVEYOR BELT

High tensile strength and small elongation in use. Small diameter of drive pulley to make the equipment smaller. High adhesion between rubber and steel cord,thus is resistant to shock and difficult to drop, so the rubber belts are long in life. The steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run away. Good troughability to form a deep trough to load more materials and prevent the materials from escaping. Users can use X-rays to inspect damages of the skeleton of steel cords to prevent accidents from happening.

Application
In various fields: coal, mining, ports, metallurgy, electric power, chemical industry, etc., conveyor belts can transport large amounts of materials over long distances and high speeds.

 

Feature
1. High tensile strength, low elongation, small transmission pulley diameter, uniform steel wire rope tension, excellent groove forming and good bonding between rubber and steel wire.
2. The steel wire rope conveyor belt has versatility, high wear resistance, cold resistance and flame retardancy according to the requirements of use and the performance of the covering rubber.
