1. Use:
Used in coal mining, ports, metallurgy, electric power, chemical industry, food, building material industrial, etc, on the strength of a long load type transport line.
2. Varieties
According to the different tensile layer materials are divides into: Cotton canvas (CC) conveyor belt, nylon (NN) conveyor belt, polyester (EP) conveyor belt.
Cotton canvas (CC) conveyor belt: A traditional, and is suitable for the short distance the conveyor belt conveying material.
Nylon(NN) by conveyor belt: Take body good flexibility, strength, impact resistance, high anti-bending sex good, into Groove type of good, use elongation is small, be applicable to the long-distance higher capacity Under the condition of high speed conveying material.
Polyester(EP) conveyor belt: Belt body high modulus, use small, heat resistance elongation, good resistance tompact, Apply to high, high speed.
NN conveyor belt (Nylon conveyor belt)
Standards:
GB/T 7984-2001, DIN22102, BS490, AS1332, RMA, JISK6322, SABS1173 etc
Types:
Besides General-used Nylon Belt, there are Fire-resistant type, Cold-resistant
type, Wear-resistant type, Heat-resistant type, Acid and alkaline resistant type,
Oil-resistant type, Antistatic electricity type,High-grade type and etc.
