Features and Applications
It is made by using multi-layer polyester-cotton canvas as the carcass layer and coating it with a general-purpose surface rubber, followed by molding and vulcanization. It is primarily suitable for conveying powdered materials, small-to-medium-sized granular materials, or less abrasive bulk goods and piece goods under normal temperature conditions.
Implementation standard
GB/T 7984-2013 “Fabric-Cord Conveyor Belts for General Use”—This standard references and adopts the international standard ISO 14890:2003.
Main Performance and Specifications
