Application
Massive task steel cord conveyor belt for general use is widely used in coal, mine, port, metallurgy, power, chemical industries and suitable for high strength,long distance and heavy load transportation of materials. The product is excellent for long distance, high abasion, high impact/tensile strength with longer service life, more excellent durability. Its cover grades are GB-L, GB-D, GB-H, and DIN Z, W, Y, X.
Features:
1. High tensile strength
2. Small elongation in use
3. Lesser elongation in use
4. Good troughabilit
Applications:
It is widely used in material delivery for coal/coke, mine, harbour, metallurgy, electric power and chemical industry.
