Product Classification

According to the framework material:

Nylon (NN) fabric flame retardant conveyor belt

Polyester (EP) fabric flame retardant conveyor belt

Product Features

Nylon (NN) canvas core flame-retardant conveyor belt has the advantages of light weight, good elasticity, high strength, impact resistance and grooving. It is suitable for conveying materials in medium and long distance, large volume and high speed.

Polyester (EP) canvas core flame retardant conveyor belt has high initial modulus, good thermal stability of belt body size, high strength, small elongation and impact resistance, which is suitable for conveying materials in medium and long distance, large volume and high speed.

Product Use

It is widely used in coal, mining, port, metallurgy, electric power, chemical industry, casting, building materials and other industries and places. It is especially suitable for material transportation in surface coal washing plant, power plant and non coal underground mining. It is used to transport non corrosive bulk, granular and powder materials, bulk materials or finished articles.
