PP textile belts ABRASION RESISTANCE POLYAMIDE / POLYAMIDE Areas of application These PP textile belts are generally used in extraction and transformation industries for conveying bulk material of large grain size at temperatures between -25°C and +60°C. • Open-pit coal mines (conveying of overburden, coal and aggregates) • Open-pit mineral mines (lime, phosphates, various ores) • Treatment of minerals • Iron and steel industries • Cement works (quarry materials and transformation) • Paper mills • Port installations • Public works • Agriculture • Sugar factories • Thermal power plants • Quarries and sand pits Top cover Our PP textile belt consists of rubber covers and moulded edges and a textile carcass. The carcass has a multiply structure comprising 2 to 5 plies of PP (polyamide warp and weft) synthetic fabric. A layer of skim gum covers each ply. Textile carcass Bottom cover The covers protect the carcass against damage, adverse weather conditions and biological and chemical aggressions. The role of the carcass is to transmit the longitudinal forces and absorb the dynamic forces generated by the falling and conveying of the material. These PP textile belts are produced with cover grades W, X, Y and Z complying with standard DIN 22102 or antiabrasive cover grade D.
