Reinforcement properties
The belt comprises a number of layers of synthetic fabrics specially treated to ensure low elongation (1 to 3.5%) and good adhesion to rubber. The length wise threads (warp) are polyester while the cross wise ones (weft) are polyamide.
This plain-woven combination ensures a high tensile strength-to-weight ratio, excellent flexibility and outstanding troughing properties, as well as high resistance to impact, and chemicals.
Other thread materials and different weaves are available on request.
Cover grades
Various cover grades can be supplied, and they are all made of high-quality rubber with extremely high resistance to abrasion, shearing and impact and excellent ageing properties. Matching the right belt to your application means generating less waste — helping you to reach your sustainability targets.
Your choice of cover grade depends on the intended application. Note that the working life of the belt is also determined by the application.
Wear-resistant
Available in X, Y, W grades (and similar) for heavy-wear conveying applications such as bulky, sharp materials like heavy, abrasive rocks. Can handle abrasion, wear, impact and other kinds of heavy-duty wear. High-quality cover grades are recommended to offer the best protection for the belt carcass.
Heat-resistant
Different types of grades are available for high-temperature applications (T120 and T200) such as clinker, coke, foundry sand and slag. Can be used for transporting material at continuous temperatures of up to 190 °C, with peaks of up to 200 °C.
Flame-resistant
Available in flame-resistant configuration to meet safety category EN 12882 for above-ground operations and EN14973 for underground applications.
