Breaker Fabrics

Reinforcing Conveyor Reliability

Breaker fabrics are critical reinforcements within steel cord conveyor belts, designed to protect the belt’s core structure from severe operational stresses. Positioned between the cover and steel cords, this layer absorbs impact, resists tearing, and prevents costly damage to the carcass.

By mitigating risk in high-impact environments, breaker fabrics help maintain uptime and reduce maintenance costs across mining and bulk material handling operations.

Features & Benefits

Enhanced Impact Protection

Engineered to absorb heavy loads and sharp material impacts, reducing stress on steel cords.

Superior Rip Resistance

Acts as a barrier against longitudinal tears, minimising the risk of catastrophic belt failure.

Extended Belt Life

Provides an additional layer of defense in harsh conditions, lowering total cost of ownership.

Adaptive Performance

The Nylon construction causes the breaker fabric to compact around piercing or trapped objects, potentially halting the belt rather than allowing a rip to grow.

Precision Weave Technology

Leno weave construction ensures dimensional stability and prevents slippage during fabrication and splicing.

    Looking for Ultimate Durability? Meet DynaFlex

    DynaFlex's advanced straight warp polyester and heavy-duty nylon matrix dissipates force more effectively than traditional Leno weave designs, delivering superior impact resistance. DynaFlex uses heavyweight straight yarns in parallel planes – lengthwise and crosswise – locked together with a unique binder to concentrate belt strength.

    Ideal for primary crushers, short-cycle systems, reclaimers, and stackers, DynaFlex ensures maximum reliability in the most punishing environments.

    Types of Breaker Fabrics

    Breaker fabrics are available in different configurations to suit varying operational demands. The choice between heavy and light breakers depends on the severity of impact and the location within the belt structure. Both types use robust textile weaves to ensure stability and performance under extreme conditions.

    Light Breakers

    Positioned on the pulley side, light breakers provide lighter-duty protection for less demanding applications. They safeguard against minor abrasions and impacts without adding unnecessary weight or complexity.

    Heavy Breakers

    Installed on the carry cover side, heavy breakers deliver maximum protection against severe impacts and abrasive materials. They are essential for belts operating in high-load, high-impact zones where durability is non-negotiable.

    Frequently Asked Questions

    Why are breaker fabrics essential in steel cord belts?
    They protect the carcass from impact and tearing, reducing downtime and extending belt life.
    Where are breaker fabrics positioned?
    Between the carry or pulley cover and the carcass, typically 1–4 mm above the steel cords.
    How do heavy and light breakers differ?

    Heavy breakers protect against severe impacts on the top cover, while light breakers provide lighter protection on the pulley side.

    What makes DynaFlex superior?

    Its unique matrix design offers exceptional impact resistance and force dissipation, outperforming standard breaker fabrics.

    Can the entire carcass use DynaFlex?
    Yes; UsFlex belts replace steel cords with a fabric carcass similar in construction to DynaFlex, delivering unmatched rip resistance and durability for new systems.
    What is a Leno Weave?

    Leno weave is a weave in which two warp yarns are woven around the weft yarns to provide a strong yet sheer fabric. The standard warp yarn is paired with a skeleton or 'doup' yarn; these twisted warp yarns grip tightly to the weft which grants improved durability to the fabric.
