The heat resistant covneyor belt could also choose cotton canvas as carcass and then covered with rubber with excellent heat resistant property.
Classify by structure:
Type 1: Same as general use conveyor belt, composed of carcass and cover rubber on top and bottom sides.
Type 2: With an additional insulation layer between crubber cover and carcass.
Classify: Divided into 4 kinds according to its varying heat resistant degree:
Type T1: To stand a testing temperature≤100°C;
Type T2: To stand a testing temperature≤125°C;
Type T3: To stand a testing temperature≤150°C;
Type T4: To stand a testing temperature≤175°C.
Usage:
Widely used in metallurgy, building material and foundry industries, to convey sintered-ores.
