Conveyor Belt Series

Index

Standard: HG2297-92 which adopts ISO4195/1-1987 and ISO4195/2-1988.

Structure: It uses cotton / polyester or nylon canvas as carcass, covers of the belt are made of rubber materials with good heat-proof of performance.

Feature: High temperature resistance, it is widely used in metallurgical industry, coking industry and casting industry, it is suitable to transport ore, heat coke, cement, melting dregs and hot casting articles etc.

Types: One is the same as that of general-used Conveyor Belt, another has a heat insulation layer between cover and carcass.

Classification: According to different testing temperature: Type 1 (testing temperature100), Type 2 (testing temperature125), Type 3 (testing temperature150).
