800S Coal Mining PVC/PVG Conveyor Belting

PVC PVG Solid Woven Conveyor Belt

Used in coal mining and other working conditions that need fire resistance and antistatic properties.

Character: Good fire resistant and anti-static properties, light weight, high strength, super anti-ripping and impact resistance.

Non pressed PVC type
Construction: After dipping with PVC on the solid woven fabric, add PVC cover on the solid carcass to from the belt.

PVG type
Construction: Based on PVC carcass, with rubber component top and bottom cover, formed after belting pressed.

The solid woven fabric uses high tensile strength and low elongation polyester long filament as warp fibre, for weft fibre, it uses high tensile and medium modulum nylon filament. The fabric is high in strength, low in elongation, high in carcass, free of separation of plies, shock resistant, anti-tear and good in troughability.

Performance:

(Underground Conveyor Belt) Flame retardant conveyor belt is made from the whole belt core via dipping and plastifying in polyvinyl chloride (PVC) dipping agent or sulfuration. It features largely in the high strength, large freight volume and stable conveyance performance. Besides, it is fire retardant, anti-static, shock resistant, wearable and corrosion resistant.

Usage:

PVC,PVG conveyor belt is mainly applicable for the underground well haulage of coal mines, and also the conveyance of materials for metallurgical and chemical industries. The whole core fire-retardant conveyor belt is divided into two types: PVC, PVG

Two types: PVC, PVG

PVC type conveyor belt's upper and lower layers are PVC coating cover, single-sided tape thickness: ≥1.0mm; PVG type belt's upper and lower layers are nitrile rubber and PVC, single-sided tape thickness: 1.5mm-4.5mm.

PVC type conveyer belt's inclined angle: <16°;

PVG conveyer belt's inclined angle: <20°.
