Conveyor belt selection rules

Belt conveyors are classified as light-duty type and heavy-duty type depending on the conveyed material, so there are different conveyor belt choices; Followings are the differences between  light conveyor belt and heavy conveyor belt.

1. The material

Light conveyor belts are generally made of PVC, PU, silica gel, Teflon, etc. These materials are non-toxic and odorless, and can be in direct contact with the conveyed objects. Heavy conveyor belts are mainly made of rubber with large odor and toxic gases prone. They are suitable for conveying ore and sand.

2. The pattern

Light conveyor belts have a large variety of patterns, such as grass pattern, diamond pattern, character pattern, cloth pattern, checkered pattern, etc. And the pattern can be selected depending on the conveying environment; while the heavy conveyor belts have relatively less patterns, including zig-zag pattern, grass pattern, plane pattern, mainly used for rock blasting and other harsh environments.

3. The thickness

The light conveyor belt has a wide thickness range from the thinnest 0.1mm to the thickest 10mm, the user can make choice as per the size of the conveyor roller; the heavy conveyor belt always has the thickness more than 7mm.

4. Usage environment

Light conveyor belt is suitable for indoor use under room temperature, and the cold-resistant conveyor belt or high temperature conveyor belt is available by changing the formula according to the different transmission temperature; heavy rubber belt has stable formula and is generally used for outdoor transportation, adapting to the harsh environment and relatively meeting  the requirements of wear-resisting, cold-resisting and heat-resisting.

5. Applicable industries

Light conveyor belts are mainly used in the material handling system of food, beverages, pharmaceuticals, chemicals, printing, wood, textiles, packaging, ceramics, stone, electronics, instrumentation, and tobacco, etc., whereas the heavy conveyor belts are mainly used in conveying systems with heavy loading and high strength requirements, such as in mines, ports, power plants, cement plants, steel mills, sand and gravel production lines and other industries.
