The difference between heavy duty conveyor belt and light duty conveyor belt

Light duty conveyor belts are suitable for many industries, including food processing, electronic toadskin, precision machinery design, postal savings, printing industry, woodworking, tobacco industry, logistics industry, etc. What is the difference between it and the heavy duty conveyor belt? Take a look.


Light duty conveyor belts are generally made of PVC, PU, ​​silica gel, Teflon, etc. The material itself is non-toxic and tasteless, and can be in direct contact with the conveying material. In order to enhance certain properties, certain formulas will be changed.

Heavy duty conveyor belt, mainly made of rubber, has a strong smell and is prone to produce toxic gases, suitable for conveying ore, sand, etc.


Light duty conveyor belt has many kinds of patterns, including grass pattern, diamond pattern, one-word pattern, cloth pattern, square grid pattern, etc. Different patterns can be selected according to the different conveying environment.

Heavy duty belts have relatively few patterns, mainly herringbone patterns, grass patterns, and planes, which are suitable for harsh environments such as rock blasting.


There are many thicknesses of light duty conveyor belts, from the thinnest 0.1mm to the thickest 10mm. Choose the appropriate conveyor belt according to the size of the conveyor roller.

The thickness of heavy duty conveyor belts is generally above 7mm.

Use environment

The light duty conveyor belt is suitable for indoor use and room temperature environment. According to the different conveying temperature, the formula can be changed to produce cold resistant conveyor belt or high temperature resistant conveyor belt.

The heavy duty conveyor belt has a stable formula and is generally used for outdoor transportation to adapt to harsh environments.

Applicable industries

Light duty conveyor belts are mainly used for material conveying systems in conventional industries such as food, beverages, medicine, chemicals, printing, wood, textiles, packaging, ceramics, stone, electronics, instrumentation, and tobacco;

Heavy duty conveyor belts are mainly used for conveying systems with heavy materials and high strength requirements such as mines, ports, power plants, cement plants, steel plants, and granaries.
