Fenner Conveyors' revolutionary concept in straight-warp conveyor belting. KordFlex® uses a high-tensile, extremely low-stretch Aramid carcass.
Like Steel Cord, Aramid fibres offer high tenacity, low elongation, and good thermal stability. But unlike Steel Cord, Aramid retains low density, chemical and fatigue resistance, and the positive handling qualities of synthetic fibre.
We use heavy-weight straight yarns in parallel planes – lengthwise and crosswise. The carcass binder like is a built-in breaker that resists impact and puncture.
Carcass weight reduction of more than 70% compared to steel cord
Especially useful in weight sensitive, high abrasion, high tension applications, the KordFlex carcass can be combined with any of Fenner Conveyors' premium cover compounds. When using KordFlex in place of existing Steel Cord belting it can result in a carcass weight reduction of more than 70%.
Greater ‘available cover’ life
The transition from a Steel Cord belt to a KordFlex belt also offers economic benefits by having greater ‘available cover’ life. This is due to the fact that the covers can be worn down much closer to the carcass without significantly compromising its impact, tear or tensile strength, providing a minimum additional 2mm of usable cover.
In our preliminary site trials, when combined with Fenner Conveyors' UltraTuff abrasion resistant cover compound, KordFlex has outperformed Steel Cord belts used in short-cycle balance machine applications:
Longer belt life in tough service
Low stretch belt approaching steel cord specifications for take up travel
Lighter weight belt that results in a greater energy savings per tonne conveyed
Less downtime due to faster splice compared to steel cord
Greater rip, tear and impact resistance
Excellent load support, trough ability and tracking
Longitudinal rip resistance more than five times of the equivalent rated multi-ply belts and steel cord belts
KordFlex allows for the use of mechanical fasteners for 'break-in'. For situations where downtime means lost production, this is a valuable option.
Available in single and dual ply construction up to ST2300.
