Direct manufacturer solutions specializing in high-tension, acid-resistant, flame-retardant, and heavy-duty rip-resistant conveyor belts designed for severe mining, metallurgical, and marine operations.
Advanced Manufacturing of Rubber & Conveying Supporting Systems Since 2004
Hebei Boao Rubber Technology Co., Ltd. is strategically situated within the Boye County Rubber Industrial Park, Baoding, Hebei Province, China. Spanning a modern manufacturing footprint of over 30 acres, we stand as a premier supplier that merges complete R&D, structural design, test-based production, and global client support. Our flagship brand, **"Jinao"**, represents elite structural integrity and has received multiple international system certifications.
Our factory possesses a comprehensive machinery ecosystem, operating advanced lines for continuous compounding, calendering, molding, vulcanizing, and exhaustive rubber quality control checks. From raw elastomer composition up to final belt tension inspections, every phase complies strictly with ISO and international safety regulations to guarantee reliable performance.
"We strictly enforce our zero-tolerance quality standard: unqualified raw compounds never cross our threshold, and finished products missing any performance rating never exit our factory."
In high-tonnage heavy industries, conveyor belt failure is one of the costliest causes of unplanned downtime. Procurement officers globally seek high-strength, rip-resistant solutions to combat severe material stresses.
Open-pit mining, iron ore refining, and smelting facilities deal with large, sharp, heavy minerals. Traditional conveyor belts are highly vulnerable to piercing by jagged rocks, leading to catastrophic longitudinal rips. Specialized rip-stop barriers, steel mesh inserts, and high-impact covers are required to ensure continuous operation.
Port operations handling coal, grains, fertilizers, and minerals rely on high-speed conveyors. A sudden tear can halt ship loading processes, resulting in massive demurrage penalties. Reliability is key, along with features like ozone resistance, UV protection, and seawater corrosion resistance for coastal port systems.
These environments involve hot sinter, clinker, slag, and coal. Materials often carry sharp foreign objects like rebar or tramp metal. The ideal belt must combine anti-tear physical properties with high-temperature resistance and self-extinguishing flame retardancy, complying with DIN and ISO standards.
How modern conveyor systems prevent tears: A detailed look at rubber compounding, reinforced carcasses, and sensor technology.
By weaving high-tensile steel cord grids above or below the longitudinal steel cords, we create an impact barrier. When a sharp object pierces the cover, it strikes these transverse steel wires, preventing the tear from propagating longitudinally.
Using optimized natural rubber and butadiene rubber compounds, we achieve tensile strengths above 24 MPa and elongation at break exceeding 450%. This elasticity allows the belt to deflect under sharp impacts rather than puncture.
Integrating electromagnetic or RFID sensing loops into the rubber plies allows the system to communicate with the drive pulleys. If a tear damages a sensor loop, the conveyor system shuts down automatically, limiting the tear length to a few meters.
Our in-house physical testing laboratory and chemical analysis room conduct rigorous testing on both raw materials and finished conveyor belts to ensure reliable field performance.
We monitor every step of production, from raw compound testing to vulcanization control. Raw materials that do not meet our specifications are rejected, and finished belts are tested before dispatch.
Our facility is equipped with tensile testers, DIN abrasion meters, dynamic fatigue testers, and rubber rheometers to provide accurate quality metrics.
Jinao® conveyor belts are used across China and exported globally, serving major operations in steel, mining, chemical fertilizers, and power generation.
We provide complete support throughout the lifespan of our conveyor belts, helping to reduce maintenance costs and prevent unplanned operational downtime.
We assist with planned replacements, splice repairs, periodic inspection services, and emergency repair response for major conveyor systems.
We supply vulcanizing materials, maintain safety stock for long-term partners, perform cover repairs, and monitor splice wear during routine checks.
Our target is to improve belt service life, reduce wear-related failures, and help optimize the performance of bulk handling systems.
We offer customized rubber compounding and carcass configurations to match specific incline, heat, chemical, or wear conditions.
Jinao® conveyor belts are utilized in demanding conditions by leading organizations in the mining, steel, cement, and power generation sectors.
Our products are manufactured to meet major international standards, including API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and TS certifications.
