If you are choosing the right conveyor belts for a coal mine, power plant or a sand quarry you should know about the basic parameters that distinguish the conveyor belts. Conveyor belts are usually specified as shown below:
Conveyor belt description
Textile of conveyor belt
Conveyor belts can be categorized based on the material of the inner layer:
P - Polyamid - Polyamid (Nylon) is used in the warp and weft of the fabric.
EP - Polyester - Polyester is used in the warp and weft of the fabric.
ST - Steel-cord - Steel-cords are used for higher strength of the belt.
The advantage of EP belts over P belts is the lower elongation of the belt under the material load.
Conveyor belt tensile strength
Tensile strength means how much the belt can be elongated in given conditions without serious damage of the belt.
The unit is computed in N/mm2.
Number of layers in conveyor belt
Number of layers of the conveyor belt specifies how many textile or steel cord layers are used in the core of the belt and thus composes the final thickness and strength. Individual layers are joined with 0,5mm to 1mm thick rubber layer.
Typically, 3-5 layers are used.
The conveyor belt can also contain breaker layer which protects against damage made by sharp materials on the conveyor belt.
Upper and lower cover layer of a conveyor belt
The upper cover layer defines the thickness of the cover layer on which the load is transported.
Conveyor belt width
The width of the conveyor belt is usually measured in mm. Typically, the width of the belts is 400mm-2400mm.
Physical-mechanical properties of conveyor belt
Conveyor belts can be further divided based on fire resistance and other properties:
