Explore our industrial-grade components designed to maximize wear resistance, load capacity, and conveyor operational lifespan.
In the heavy industrial landscape, conveyor systems are the arteries of production. The efficiency of mining, steel manufacturing, power generation, and port logistics relies heavily on the durability of rubber conveyor belts. In these demanding environments, conveyor belts face constant mechanical challenges: high-velocity impact from abrasive aggregates, sharp fragment punctures, chemical breakdown from oils, and structural stress from high inclination angles.
At Hebei Boao Rubber Technology Co., Ltd., we develop our "Jinao" brand products based on the physics of elastomer wear. The longevity of a wear-resistant conveyor belt depends on two parameters: the cover compound's molecular composition and the reinforcing carcass's tensile structure. Under the DIN 22102 standard, wear resistance is categorized by volume loss under friction (expressed in cubic millimeters):
Designed for severe applications, DIN-W specifies a maximum abrasion loss of only 90 mm³. Ideal for quartz, metallic ores, sinter, and large-sized granite handling.
Featuring a limit of 120 mm³ loss. Provides structural protection against high drop heights where sharp ores strike the belt, preventing surface gouging.
Maintains a maximum 150 mm³ loss. The optimal solution for coal, sand, limestone, cement, and grain conveying under normal operating conditions.
Our formulation incorporates Styrene-Butadiene Rubber (SBR) blended with Natural Rubber (NR) and reinforced with ultra-fine carbon black. This combination provides a high-density molecular network that prevents micro-cracks from propagating, ensuring long-term performance and reduced maintenance costs.
Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. Over the last 22 years, our facility has grown to cover more than 30 acres, developing into a leading engineering hub that integrates industrial research, design, production, and after-sales service.
Our manufacturing plant operates state-of-the-art production lines for calender rolling, continuous vulcanization, and finished product inspection. Our operations are certified under the ISO 9001 quality management framework, ensuring strict quality control from raw material selection to dispatch.
Our facility houses an independent chemical analysis lab and a physics testing laboratory. No raw materials enter production, and no finished belts leave our factory, without meeting international standards.
Vulcanization temperature, pressure, and curing time are monitored via PLC systems. This ensures uniform cross-linking of the rubber molecules across the belt's length and width, eliminating weak spots.
We test adhesion levels between the cover rubber and core plies (EP, NN, or Steel Wire) to prevent delamination under high tension and tight pulley wrapping.
Sourcing wear-resistant conveyor belts from China provides significant supply chain advantages. Hebei Boao Rubber Technology Co., Ltd. combines cost efficiency with reliable production capacity to serve global industries.
Global procurement teams look for conveyor components that match their specific operational requirements. We manufacture products tailored for diverse industrial sectors:
Our high-tensile steel wire core conveyor belts handle high-tonnage primary ores. For underground coal mines, we supply fire-retardant belts that meet safety standards like MSHA and EN 12882.
Handling clinker, slag, and hot sinter requires heat-resistant conveyor belts. Our EP/NN fabric belts are designed to withstand temperatures up to 200°C (with peak peaks up to 250°C) without hardening or cracking.
Our belts operate at high speeds of 4-6 m/s under varying maritime weather conditions. They feature ozone-resistant cover layers that prevent cracking from salt air and UV exposure.
For steep-angle conveying in space-restricted environments, our high-angle wavy edge rubber conveyor belts and patterned chevron belts support material transport at angles up to 90 degrees, preventing rollback and material loss.
Our commitment to quality is backed by certified testing processes and partner collaborations with major industrial groups.

A reliable conveyor belt requires ongoing maintenance and support. Hebei Boao Rubber Technology Co., Ltd. provides comprehensive service programs to help clients extend the life cycle of their conveyor assets:
We work with procurement teams to monitor belt wear rates and establish localized stock buffers. This approach helps minimize unplanned downtime in high-throughput lines.
We provide detailed technical guidance for splicing methods, including hot vulcanization and cold bonding, to ensure splice strength matches the carcass specifications.
Our engineers can adjust cover rubber properties to meet specific operating conditions, such as resistance to acidic fertilizers or high-temperature slag.
The industrial conveyor market is moving toward greater efficiency and intelligence. Key trends shaping the future of bulk material handling include:
Get answers to common technical and procurement questions about our wear-resistant conveyor products.
Selection depends on the material type, size, drop height, and system load. Use Grade W (max 90 mm³ loss) for sharp, high-density abrasive ores. Choose Grade X (max 120 mm³ loss) for large drop heights with high impact. Choose Grade Y (max 150 mm³ loss) for general bulk materials like coal, grains, and limestone.
We offer Polyester-Nylon (EP) for low elongation and high strength, Nylon-Nylon (NN) for high elasticity and troughability, and Steel Wire Rope Core (ST) for long-distance, high-tension applications requiring minimal stretch.
All production batches are tested in our laboratory. We check tensile strength, elongation at break, cover-to-carcass adhesion, and abrasion loss under DIN 53516 standards to ensure consistency.
Our heat-resistant belts are classified into T1 (up to 125°C), T2 (up to 150°C), and T3 (up to 200°C). We also manufacture specialized compounds that handle intermittent spikes up to 250°C.
We use robust steel cores, heavy-duty waterproof wrapping, and custom packaging to protect the belt edges and roll structure during ocean transport.
Yes. We can customize belt widths from 300mm to 2200mm, with cover thickness combinations (e.g., 6mm top + 2mm bottom) tailored to your system's load profile and operating conditions.
