Precision engineered conveyor belts, rollers, and mechanical accessories sourced directly from our quality-certified manufacturing facilities in China.
In heavy bulk material handling operations, the transfer point is historically the most critical vulnerability zone. As materials dump from one conveyor to another, kinetic forces and air pressure differentials create extreme turbulence. Without effective lateral confinement, this leads to heavy material loss, airborne dust emissions, and severe component wear.
This is where a premium-grade Skirting Rubber Conveyor Belt Sealing System becomes essential. Positioned at the loading zones beneath the hopper, skirting rubber acts as a dynamic mechanical seal. It retains both fine particles and heavy aggregate on the belt, preventing material from escaping past the skirtboards. Effective sealing not only reduces clean-up costs but protects downstream mechanical parts such as idlers and pulleys from abrasive damage.
Located in the prominent Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. has been a pioneer in industrial conveyor components since its establishment in 2004. Operating from a highly advanced facility spanning over 30 acres, we deliver comprehensive R&D, design, manufacturing, and technical support services.
Under our trademark brand "Jinao", we provide high-performance conveyor belts and mechanical accessories. Equipped with advanced rolling, shaping, vulcanization, and material testing systems, our laboratory continuously monitors compliance from raw compound formulation to finalized global shipments.
Selecting the optimal elastomeric compound is crucial to achieving a perfect seal without causing premature wear to the main conveyor belt carcass.
Engineered for exceptional abrasion resistance and tensile flexibility. With a hardness range of 50 to 65 Shore A, SBR blends provide an adaptive soft seal that yields under excessive pressure, minimizing wear on the belt's top cover while keeping dust fully enclosed.
The pinnacle of engineering for heavy wear zones. Dual-durometer skirting combines a rigid backing (approx. 70-80 Shore A) for structural support against aggregate force, and a highly flexible sealing lip (approx. 50-60 Shore A) that conforms to the belt's dynamic surface variations.
For severe operational conditions, we formulate flame-retardant (FR), anti-static (AS), oil-resistant, and high-temperature-resistant skirting. These compounds meet global safety protocols in underground coal mining (MSHA/ATEX) and chemical plants.
| Material Compound | Hardness (Shore A) | Tensile Strength (MPa) | Elongation at Break (%) | Key Applications |
|---|---|---|---|---|
| Premium Natural Rubber / SBR | 50 ± 5 | 12 - 15 MPa | ≥ 400% | Standard aggregate plants, sand/gravel handling, general-purpose conveyors |
| Dual-Durometer Polyurethane | 80 (rigid) / 55 (seal) | ≥ 25 MPa | ≥ 500% | Heavy iron ore, gold/copper mining, high-speed transfer chutes |
| Neoprene / Nitrile Blend | 60 ± 5 | 10 - 12 MPa | ≥ 350% | Oil-refinery waste, grain processing, oil-treated coal operations |
| Anti-Static / Flame Retardant | 65 ± 5 | 11 - 13 MPa | ≥ 300% | Underground coal mines, grain silos, explosive gas environments |
We deliver unmatched quality and performance backed by advanced manufacturing and comprehensive quality control frameworks.
Our factory features an independent chemical analysis laboratory and physical testing facility. We monitor every stage of production from raw elastomer procurement to physical vulcanization. We strictly enforce a policy: unqualified raw materials never enter production, and non-conforming products never leave our warehouse.
Employing professional quality inspectors and state-of-the-art testing equipment, we perform regular abrasion loss test cycles, elongation trials, and ozone degradation testing to ensure the long service life of our skirting rubber and conveyor accessories.
