Audited Supplier PVC/PVG underground conveyor belt for coal mine
1. Applications of PVC Conveyor Belt
Solid woven fire resistant conveyor belt (PVC type)
The belt is mainly used in underground coal transportation, also in metallurgy and chemical industry. It is manufactured by plasticizing or vulcanizing solid woven core, which is impregnated in PVC paste.
2. Characteristics of PVC Conveyor Belt
-high tensile strength
-big-volume & smooth transportation
-good fire/static/impact/abrasion/corrosion resistance.
-transporting angle<16 degree
