Full definition
An abrasion-resistant belt is designed specifically for environments where sharp, abrasive materials are handled, such as in mining, quarrying, and industrial material transport. These belts feature rubber covers that are engineered to withstand the severe wear associated with materials like crushed rock, ore, and sand. The effectiveness of these belts is primarily determined by the rubber cover grade, which is classified under international standards. According to ISO 14890, abrasion-resistant belts are categorized into three grades based on their volume loss during abrasion testing: Category H for the highest abrasion resistance with a volume loss of ≤120 mm³, Category D for high resistance with a loss of ≤150 mm³, and Category L for normal resistance with a volume loss of ≤200 mm³. Additionally, the DIN 22102 standard includes grades such as Y (≤150 mm³) and W (≤100 mm³), the latter being considered a premium option for extreme wear scenarios.
