Engineered to prevent material rollback across steep inclines, mining structures, and industrial mixing plants.
Located in the prestigious Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. (established in 2004) has spent over two decades developing high-performance bulk material handling solutions under our flagship brand "Jinao".
We integrate the entire lifecycle of industrial conveyance: design, molecular compound research, custom vulcanization profiling, mechanical system integration, and global supply logistics. Equipped with advanced automated mixing lines, complex calenders, heavy vulcanizing presses, and a comprehensive in-house physical & chemical testing laboratory, we ensure that every single belt manufactured meets local and international technical standards before leaving our facility.
In modern bulk handling industries, material transshipment represents a primary operation cost factor. Traditional flat rubber belts are limited by physics; at angles exceeding 15° to 18° (depending on the material's internal friction angle), materials begin to slide backward. To circumvent this constraint, the global bulk shipping, mining, and civil infrastructure markets have rapidly adopted patterned conveyor belts (specifically Chevron, Herringbone, High-Angle Sidewall, and custom-molded profile designs).
Today, patterned conveyor systems serve as the backbone of dry bulk handling terminals, metal smelting plants, underground coal mines, and complex infrastructure construction hubs. By utilizing continuous profile patterns (ranging from low 5mm profiles for agricultural grain handling to heavy-duty 32mm high-profile chevron patterns for wet sand and aggregate transportation), operations can safely convey raw materials at angles up to 40° or even higher. This saves valuable land space, minimizes transfer tower requirements, and reduces structural metal expenses.
Moving run-of-mine ores, aggregate materials, and crushed limestone up steep open pits. Requires massive tear and impact resistance, alongside heavy rubber profiles to resist abrasion.
Coking coal and iron ore pellet transport. Demands a combination of chemical structural durability, heat-resistant rubber compounds, and specialized patterns for damp environments.
High-speed elevator conveyors handling soybean, corn, and fertilizer bags. Demands food-safe rubber matrixes and specialized non-clogging low-profile patterns.
The industrial demand for patterned belts is no longer limited to simple traction. Modern conveyor lines operate at faster speeds, higher volumes, and under increasingly severe climates. At Hebei Boao Rubber Technology, our material science laboratory targets three primary fields of technical evolution:
Our independent laboratory maintains strict control over raw materials, intermediate rubber sheets, and final vulcanized belts. We verify raw polymer batches using moving die rheometers (MDR) and gas chromatography. Finished rubber components are subjected to exhaustive mechanical and chemical testing:
Calendering & Shaping Machine
Peeling Adhesion Test
Steel Cord Pull-out Tester
Dynamic Fatigue Tester
Abrasion Tester
Physical Property Verification
Different operating environments require specific configurations of conveyor belt patterns, cover compound grades, and reinforcing carcasses. Choosing the right design prevents premature wear, belt slippage, and material degradation. Below are three common field challenges where Boao Jinao belts are deployed:
Application: Cement batch plants and mobile crushers operating at angles of 25° to 35° with wet sand and gravel.
Solution: 15mm-25mm Chevron patterned belts. Built with an abrasion-resistant DIN cover compound, this configuration prevents rollback while allowing rainwater drainage to keep the feed dry.
Application: Processing plants moving acid-treated phosphate and potash powders up to silos.
Solution: Acid and alkali-resistant base covers combined with a molded multi-V pattern. The vulcanized structure prevents corrosive liquids from reaching the internal fabric layers, preventing ply separation.
Application: Transporting hot blast furnace feeds and sintered ores at angles up to 22°.
Solution: Heat-resistant (T200/T250) base rubber formulated with EPDM. This compound resists thermal cracking and hardening caused by hot materials, while molded profiles maintain grip.
Conveyor technology is moving toward smarter, more sustainable designs. Hebei Boao Rubber Technology is updating our Jinao brand products to keep pace with these shifts. Below is our engineering roadmap for the next generation of industrial conveyor systems:
