Black Flame retardant conveyor belt NN300 Special Conveyor Belts

1. Concept

This product is primarily designed for underground haulage in coal mines and is also applicable to material conveying scenarios in the metallurgical and chemical sectors. The full-core flame-retardant conveyor belt can be categorized into two types: PVC type and PVG type.

The upper and lower cover layers of the PVC-type conveyor belt are both made of PVC cover rubber, with the single-side rubber thickness being no less than 0.8mm; the upper and lower cover layers of the PVG-type conveyor belt are composed of nitrile rubber and PVC composite materials, and the single-side thickness ranges from 1.5mm to 4.5mm. In terms of application parameters, the maximum allowable conveying inclination angle of the PVC conveyor belt is less than 16°, while that of the PVG conveyor belt is less than 20°—both are suitable for coal mine underground conveying operations.

2. The longest service life of the belt body is determined by the following factors

(1) A dense belt core woven from warp and weft filaments and covering cotton spinning;

(2) Impregnated with specially formulated PVC material to achieve extremely high bonding strength between the tape core and the cover rubber;

(3) Specially formulated cover rubber; so that the belt body is resistant to impact, tearing and abrasion.

3. Mechanical properties

The flame-retardant conveyor belt has excellent mechanical properties and can provide users with the longest service life and economical installation and use.

4. Product structure

The flame-retardant conveyor belt adopts the integral belt core as the frame material, and is made by dipping and coating PVC material with excellent anti-static and flame-retardant properties and then plasticizing.
