Steel Cord Heat Resistant Conveyor Belt

High strength conveyor belt is suitable for the working conditions which are long distance, high speed and heavy load transportation. To convey the powdery, granular materials and blocked materials with no corrosivity, such as coals, sands and stones. It also suitable for heavy load and high speed transportation of materials, which are widely used in coalmines, mines, chemical industry,metallurgy. construction, ports, and some other area. The rubber covers of high strength conveyor belt adopts high strength sizing, and the skeleton is adhered by multi plies of quality nylons or poly curtains.
