Heat resistant conveyor belts
When the temperature of the materials being transported exceeds 60°C, it is more economic to employ a heat resistant conveyor belt. The conveyor belt may be damaged by heat, developing cracks or abrasion through, stiffening or softening of the rubber cover and doing separation between plies or between rubber and ply.
Heat resistant conveyor belts are employed to convey hot sintered ore, hot pellet, hot clinker, hot chemical, fertilizer, hot cement and other hot temperature materials.
The carcass is made of polyamide / polyester (EP) , polyester / polyester(EE) , polyamide / polyamide (PP) fabrics.
Characteristics of heat resistant conveyor belts
The surface temperature of heat resistant conveyor belts vary depending on the type of material, belt speed, loading rate and size depending on circumstance condition. In order to choose the proper heat resistant conveyor belt, it is necessary to take into consideration both the temperature of materials to be conveyed and the temperature of the belt’s surface.
