In the global mineral processing and heavy infrastructure domains, operational continuity depends on the mechanical integrity of structural components. Henan Hanhai Metallurgy Mining International Trade Co., LTD serves as an engineering anchor, specializing in the design, metallurgy, casting, and precision-machining of heavy cast steel and cast iron components. Backed by ISO9001 and CE certifications, the company produces high-performance machinery and castings capable of resisting massive stress profiles, abrasive friction, and fatigue cycle failures.
Our casting facilities feature advanced manufacturing infrastructure, enabling an annual production output exceeding 80,000 metric tons. Our work addresses the demands of large-scale planetary systems, rotary cement kilns, hydro-electric generation equipment, and ultra-high capacity primary crushers. Rather than operating simply as a casting foundry, Henan Hanhai functions as a co-development partner. We integrate material science design with vertical manufacturing lines to supply reliable components across Asia, Europe, the Middle East, and South America.
Our history reflects a long-term commitment to technological evolution. Founded in 1997 with a focus on heavy-duty castings, Henan Hanhai has consistently upgraded its capabilities to meet modern industrial needs:
In high-throughput mining operations, primary crushing is the gateway process. Modern aggregate, copper, and iron ore extraction plants rely on Gyratory and Cone Crushers to reduce hard run-of-mine (ROM) materials into manageable fractions. Understanding the mechanical differences and similarities between these two systems is critical for selecting the right option for a given application:
Features a steep crushing chamber and a long, vertically suspended main shaft. A heavy eccentric sleeve drives the spindle at the bottom, creating a continuously shifting crushing gap.
Utilizes a flatter crushing chamber and a shorter spindle support structure. Built for higher rotational speeds and larger strokes, providing excellent secondary, tertiary, and quaternary reduction ratios.
Both systems subject their structural housings (mantles, bowls, upper/lower shells, and eccentric hubs) to immense fatigue loading and high radial stresses.
By manufacturing our components with micro-alloyed cast steel (such as Mn18Cr2, Mn22Cr2) and using automated, non-destructive testing (NDT), Henan Hanhai ensures high wear life and excellent fracture toughness.
Gyratory crushers are designed for continuous, high-volume operations, often serving as the primary crushing stage directly after truck dumping. Their large feed openings allow them to accept raw boulders without pre-screening. Cone crushers, conversely, are typically used in closed-loop systems to achieve target size distributions for downstream milling circuits. Because both machine styles endure high stress, their long-term reliability depends heavily on the quality of their cast components, including the main frames, adjustment rings, head centers, and countershaft housings.
The crushing industry is undergoing a transition driven by digitalization, automation, and material science. To meet these demands, Henan Hanhai has established a technical roadmap focused on the following areas:
Traditional high-manganese steel (Mn13) is often insufficient for processing abrasive ores. We have developed a range of micro-alloyed materials featuring additions of Chromium (Cr), Molybdenum (Mo), and Nickel (Ni). These alloys undergo a multi-stage water-quenching heat treatment to produce a micro-structure with high work-hardening capabilities. When subjected to impact loads, the surface hardness increases rapidly from 220 HBW to over 500 HBW, while the core remains ductile to absorb shock loading.
To eliminate internal casting defects such as shrinkage cavities, micro-porosity, and hot tearing, our engineering department utilizes Magmasoft solidification simulation software. By modeling the thermal currents and crystallization stages of 30-ton to 50-ton steel pours, we optimize riser locations and chilling parameters. We also use FEA modeling to simulate stress concentration points under actual operating conditions, allowing us to reinforce high-stress areas during the casting stage.
Modern mining projects increasingly require sensor integration to monitor machine health. Henan Hanhai works with system integrators to pre-engineer castings with dedicated channels and cavities for temperature probes, vibration sensors, and ultrasonic wear-monitoring devices. This supports predictive maintenance programs, helping operators avoid catastrophic failures and costly downtime.
Recent supply chain disruptions have highlighted the value of resilient manufacturing partners. Henan Hanhai’s operations in Henan Province benefit from a mature industrial ecosystem that supports reliable lead times and cost-effective production:
Our proximity to primary raw material suppliers ensures a stable supply of high-grade steel scrap, ferro-alloys, and metallurgical coke. Our vertically integrated facility features large-scale electric arc furnaces (EAF), LF refining stations, and VD vacuum degassing systems. This integration allows us to manage quality and scheduling without relying on third-party smelting services, reducing production bottlenecks and lead-time variability.
Additionally, our in-house machining division features large CNC gantry milling machines, vertical lathes capable of handling parts up to 10 meters in diameter, and precise boring machines. By performing casting, heat treatment, machining, and final inspection under one roof, we eliminate intermediate shipping costs and maintain consistent quality standards across the entire manufacturing cycle.

Industrial machinery must be designed to withstand localized environmental challenges and meet varying regional compliance frameworks:
In high-altitude regions such as the Andes in South America, low ambient temperatures can cause standard carbon steels to fall below their ductile-to-brittle transition temperature, increasing the risk of structural cracking. For these locations, Henan Hanhai supplies low-temperature impact-resistant cast steels. We verify material performance through Charpy V-notch impact testing down to -40°C, helping ensure operational safety in challenging climates.
Modern environmental standards require effective dust and noise management. Our crushing components are designed to interface seamlessly with modern water-mist spray rings, localized dust collection systems, and acoustic enclosures. We focus on providing precise dimensional tolerances along mating surfaces to prevent dust leakage and reduce structural vibrations, helping operators meet local environmental requirements.
Different markets require compliance with specific certification standards. Henan Hanhai provides complete, traceable documentation packages for every project. This includes material mill certificates to EN 10204 3.1, non-destructive testing reports (UT/MT/PT), welding procedure specifications (WPS) for structural repairs, and CE certificates of conformity. These documents help ensure smooth importing, commissioning, and safety audits at the operational site.
