Product description

Performance characteristics

It is suitable for conveying sintered ore, coke, cement clinker of granule, powder, block and other materials in metallurgy, building materials and other industries.

1、Adopt high strength and low shrinkage polyester canvas, cotton canvas and polyester-cotton canvas as skeleton layer.

2. The upper and lower surfaces are covered with a certain thickness of high-temperature or heat-resistant rubber.

Full thickness performance Refer to GB/T20021-2005 "Canvas core heat-resistant conveyor belt" standard.
