Hebei Boao Rubber Technology Co., Ltd. ("Jinao" Brand)
Founded in 2004 and spanning over 30 acres in the Boye County Rubber Industrial Park, Baoding City, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. has established itself as an elite pioneer in the Chinese material handling sector. Under our signature "Jinao" brand, we integrate advanced chemical research, mechanical design, precise formulation, and large-scale manufacturing to deliver world-class conveyor belting and machinery components.
Equipped with state-of-the-art rolling mills, structural forming lines, computerized vulcanization presses, and raw-material-to-finished-product test rigs, our manufacturing facility meets the stringent demands of global mineral, metallurgical, and logistic supply chains.
Unlocking information gain to achieve optimized Total Cost of Ownership (TCO) in conveyor belting operations.
In modern industrial operations, conveyor systems are the lifeblood of bulk material handling. As processing volumes soar in steel mills, cement works, and coal mines, standard textile belting often falls short due to high elongation, early structural wear, or failure under heavy impact. This has catalyzed a structural shift toward engineered Reinforced Rubber Belting.
Reinforcement techniques fall into two primary structural classes: Multi-Ply Fabric (EP/NN/PP) and Steel Wire Rope Core. Polyester-Polyamide (EP) fabric belts are valued globally for their high modulus, low elongation under load, and exceptional resistance to rot and moisture. Nylon-Nylon (NN) structures offer maximum elastic resilience, allowing high troughability and resistance to constant impact shock. Steel Cord Core (ST) belting stands at the apex of tension capability, offering minimal stretch over long-distance, high-capacity routes with built-in electronic or structural rip-stop layers.
For operations handling hot clinker, sintered ore, or slag, standard rubber hardens, cracks, and degrades rapidly. Specialty compounds like EPDM and Chlorobutyl are engineered to withstand continuous material temperatures ranging from 120°C up to 250°C, preserving rubber elasticity and preventing delamination.
Underground mining demands safety. Our Flame Retardant conveyor belts are engineered to meet strict international standards (ISO 340, DIN EN 12882). Formulated with self-extinguishing polymers, they prevent combustion propagation, minimizing hazard risks in enclosed tunnels.
Transporting fertilizer, raw grain, or machine-oiled minerals requires customized NBR or CR coatings. Without specific oil-resistant compounds, rubber swells, loses tension, and slips, causing system tracking failures and unplanned downtime.
| Reinforcement Type | Common Standards | Tensile Range (N/mm) | Primary Industrial Applications | Key Operational Advantage |
|---|---|---|---|---|
| EP (Polyester/Nylon) | DIN 22102, ISO 10247 | 200 - 3150 | Mining, Cement, Steel Plants | Low elongation, high moisture resistance |
| NN (Nylon/Nylon) | GB/T 7984 | 200 - 3150 | Quarries, Aggregate Processing | Excellent impact absorption, high flexibility |
| Steel Cord (ST) | DIN 22131, ISO 15236 | 500 - 7500 | Overland Long-haul, Deep Mining | Minimal stretch, longest service life |
| Solid Woven (PVC/PVG) | BS 3289, MSHA | 500 - 2000 | Underground Coal Mining | Exceptional flame resistance and puncture safety |

How we design custom conveying systems to meet specific vertical industry challenges.
For open-cast and deep underground mining, materials are abrasive and vertical lifts are demanding. We recommend steel cord belts combined with rip-resistant sensor loops. These systems manage high tonnage over long center distances with minimal elongation, reducing structural take-up requirements.
Clinker discharging requires thermal resilience. Our EPDM heat-resistant belts are designed to withstand temperatures up to 220°C (with peaks at 250°C), resisting crack propagation and cover wear to keep production lines moving.
Handling sintered materials and slag demands high heat resistance and impact protection. Our multi-ply EP belting with reinforced rubber covers delivers reliable service under mechanical loading, hot materials, and chemical exposure.
Optimizing conveyor life cycle from installation to maintenance.
A conveyor belt is only as strong as its splice. Hebei Boao Rubber Technology Co., Ltd. provides comprehensive engineering guidelines and support for splicing, commissioning, and system maintenance. We offer tailored technical service plans to keep your operations running smoothly.
Detailed parameters for hot vulcanizing, cold bonding, and mechanical fasteners, ensuring high-strength joints that match the base belt's tension rating.
We collaborate with major operators to coordinate spare rolls and essential system parts, helping minimize downtime during unscheduled maintenance.
On-site inspection plans, cover wear profiling, tracking diagnostics, and preventative repair protocols to extend the service life of your conveyor system.
Innovative material science and smart monitoring technologies driving the next generation of conveyor systems.
By integrating bio-based silica compounds and recycled rubbers without compromising abrasion resistance, we aim to reduce our carbon footprint, helping global mining and processing clients meet their environmental targets.
We are developing rip-detecting belts with embedded electronic sensors. These loops communicate with conveyor control drives to instantly stop the system if a tear occurs, preventing extensive belt damage.
Our research focus includes low roll resistance (LRR) rubber covers. These reduce the indentation resistance of the belt over idlers, lowering overall system energy consumption by up to 15% on overland conveyors.
