PVC Conveyor Belt, Solid Woven Conveyor Belt, Fire Resistant Conveyor Belt Factory
1. Applications
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
-high tensile strength
-big-volume & smooth transportation
-good fire/static/impact/abrasion/corrosion resistance.
-transporting angle＜16 degree
