When the temperature of the conveyed materials exceeds 60ºC, it makes sense to use a heat resistant conveyor belt. Extreme heat damages a regular multi-ply conveyor belt causing it to develop cracks or premature abrasion due to the alterations in the rubber hardness eventually leading to the separation between plies and carcass. The compound used for the covers of heat resistant conveyor belt has excellent heat and abrasion resistance to protect the conveyor belt and prolong its service life. Heat resistant conveyor belts often carry hot sintered ore, pellets, clinker, chemicals, fertilizers, cement and other similar hot materials.
The carcass consists of 2,3,4,5 or 6 plies of synthetic EP (Polyester-Nylon) fabrics which feature low elongation and good tensile strength. The plies fabric plies are dipped and separated by heat resistant rubber compound and heat resistant covers are applied.
