Why Trust Fenner Dunlop Americas with Your Plied Belt Purchase?
Answer: Millions of feet per year, Millions of reasons to purchase Fenner Dunlop’s PSR® premium plied conveyor belting!
Fenner Dunlop’s core business is conveyor belting. Each belt is engineered to produce measurable, sustainable results that assist the end-user in reducing costs, avoiding costs and improving revenue. Fenner Dunlop emphasizes higher performance standards by standing with each customer to tailor a total approach to their requirements.
PSR is Fenner Dunlop Americas premier heavy-duty plied conveyor belt product line. PSR is constructed with tough synthetic fabric plies vulcanized together with premium rubber skims, creating superior adhesions to form a high performance carcass. Armoring this carcass with the correct cover compound guarantees maximum maintenance-free belt life. Fenner Dunlop offers a full range of cover compounds to suit each application.
Experience in Belt Manufacturing Makes All the Difference!
The proper carcass material in many applications will determine total belt life. Whether conveying coal, aggregate, sand, grain, wood products or mineral ore, PSR can be manufactured to suit a specific application by utilizing our standard carcass or our custom carcass constructions:
1. Standard Carcass – Polyester Warp with Nylon Filling
The polyester/nylon carcass design offers the advantages of low overall stretch and excellent impact resistance properties. The nylon weft yarns, with its lower modulus and higher stretch characteristics, will accept more impact from sharp objects and impingement from trapped materials without fracturing. This feature makes nylon a logical choice for the crosswise or weft member in the PSR belt fabric. The polyester warp yarns yield superior troughability and fastener retention.
2. Custom Carcass – Nylon Warp with Nylon Filling
Replace with: Fenner Dunlop manufactures a custom nylon/nylon carcass construction when there is a need for low modulus/high stretch conveyor belts dictated by specific applications.
BELT ELONGATION
PSR belts will elongate from 1.5% to 2.0% of total belt length depending on whether the carcass is the 110,125, 200, 250 or 300 LB/PLY fabrics. These percentages are at full rated tension for the belt, elastic and permanent according to ISO 9856. This elongation is the total for the life of the belt under normal operating conditions.
Unlike competitive belts in the market, an initial break-in period where fasteners must be installed to compensate for excessive elongation is not needed with PSR conveyor belts. Fenner Dunlop Americas PSR belts can be installed and vulcanized in one trip reducing down time and costs by eliminating extra splices due to stretch.
SAFETY FACTORS
The minimum safety factor for all PSR fabrics is 10 to 1 per ply. With polyester having a high modulus, excess elongation is not a consideration. Excessive elongation will also cause a belt to shrink in width, resulting in a permanent cupping condition.
