Rubber conveyor belts are one of the essential parts of belt conveyors. They are used for transporting large quantities of bulk materials, as well as piece goods, packages, and other finished products.
They are applied in almost all branches of industry: mining, agriculture, petrochemical, wood, and construction material industry.
They are indispensable in heavy industry, steelworks, foundries, coking plants, power plants, mines, cement plants, brickworks, quarries, glassworks, chemical industry, sugar refineries, saltworks, silos, waste recycling plants, and so on.
Rubber conveyor belt system
They consist of a so-called “core” and a protective rubber layer (the so-called “cover” or “outer layer”).
The core of the belt consists of EP fabrics made of longitudinally arranged polyester fibers with a nylon weft. It is characterized by flexibility, low weight, high tensile strength, and limited elongation.
Rubber layers (the cover) protect the core from mechanical, thermal, and chemical effects of the environment, transported material, and wear caused by rollers on the conveyor.
The thickness of the upper rubber layer (the cover) usually increases in line with the increase in the belt’s tensile strength, while the lower rubber layer is somewhat thinner due to less exposure to damage. They comply with DIN 22102 and DIN 22103 standards.
The method of labeling the belt is shown in the example for the belt:
EP – 400/3 – 4/2 – Y
According to which the indicated labels refer to:
EP Type of fabric (in the core) 400 Minimum breaking load (per belt width – Fb min) 3 Number of layers of fabric in the belt core 4/2 Thickness of the rubber protective layer (upper/lower in mm) Y Special properties of the belt Standard belts regarding the breaking load and the number of EP inserts in the core
They are available in (standard) widths of: 300, 400, 500, 600, 650, 800, 1000, 1200, 1400, 1600, 1800, and 2000 mm.
