PSR High Performance BeltingPSR is Fenner Dunlop Americas premier heavy-duty plied conveyorbelt product line. PSR is constructed with tough synthetic fabric pliesvulcanized together with premium rubber skims, creating superior adhesionsto form a high performance carcass. Armoring this carcass with the correctcover compound guarantees maximum maintenance-free belt life. FennerDunlop offers a full range of cover compounds to suit each application:General Service, Fire Retardant, Fire & Oil, Oil Resistant, Heat Resistant,Heat & Oil and Specialty CoversExperience in Belt ManufacturingMakes All the DifferenceThe proper carcass material in many applications will determine total belt life.Whether conveying coal, aggregate, sand, grain, wood products or mineralore, PSR can be manufactured to suit a specific application by utilizing ourstandard carcass or our custom carcass constructions:1. Standard Carcass - Polyester Warp with Nylon FillingThe polyester/nylon carcass design offers the advantages of low overall stretchand excellent impact resistance properties. The nylon weft yarns, with itslower modulus and higher stretch characteristics, will accept more impactfrom sharp objects and impingement from trapped materials withoutfracturing. This feature makes nylon a logical choice for the crosswise or weftmember in the PSR belt fabric.2. Custom Carcass - Nylon Warp with Nylon FillingFenner Dunlop manufactures a custom nylon/nylon carcass constructionwhen there is a need for low modulus/high stretch conveyor beltsdictated by specific applications.4
Belt ElongationPSR belts will elongate from 1.5% to 2.0% of total belt length depending onwhether the carcass is the 110, 125, 200, 250, or 300 LB/PLY fabrics. Thesepercentages are at full rated tension for the belt, total elastic and permanentelongation, when tested in accordance with ISO 9856. This elongation is thetotal for the life of the belt under normal operating conditions.Unlike competitive belts in the market, an initial break-in period wherefasteners must be installed to compensate for excessive elongation is notneeded with PSR conveyor belts. Fenner Dunlop Americas PSR belts canbe installed and vulcanized in one trip, reducing down time and costs byeliminating extra splices due to stretch.Safety FactorsThe minimum safety factor for all PSR fabrics is 10 to 1 per ply. Withpolyester having a high modulus, excess elongation is not a consideration.Excessive elongation will cause a belt to shrink in width, resulting in apermanent cupping condition.Choose PSR When You Need the Right Belt for the JobFenner Dunlop Americas, with its many years as a textile manufacturer, has theability to match the carcass design and the carcass materials to the application.This engineered approach results in performance you can measure.▲ Excellent load support▲ Unsurpassed resistance to abrasion, cutting, gouging and tearing▲ Low stretch▲ Increased fastener retention▲ Longer service life than most other plied belts▲ Decreased downtime▲ More material conveyed▲ Savings to the bottom line!5
