In high-throughput mineral processing and large-scale mining operations, the gyratory crusher serves as the heart of the crushing circuit. Processing thousands of tons of hard rock per hour demands metallurgical integrity that standard manufacturers simply cannot deliver. Our engineering solutions address the main stressors within the eccentric assembly, bottom shell, main shaft, and spider arms.
By integrating advanced finite element analysis (FEA) with decades of casting experience, Henan Hanhai Metallurgy Mining delivers casting components designed to withstand cyclic loading, extreme impact force, and abrasive wear. Whether you are crushing granite, iron ore, or gold-bearing quartz, our systems maximize uptime and optimize cost-per-ton performance metrics.
Henan Hanhai Metallurgy Mining International Trade Co., LTD is a leading heavy foundry manufacturer in China, specializing in the engineering, casting, and machining of large-scale cast steel and cast iron parts.

For more than two decades, Hanhai Casting has dedicated its core research to high-performance mining equipment.
Hanhai Casting was established with a core focus on heavy steel and iron castings, laying a solid technical and production foundation for custom configurations.
Introduced advanced electric arc melting and vacuum molding systems, expanding production capacity to serve major high-demand mineral handling projects.
Achieved ISO9001 certification, upgraded non-destructive testing (NDT) operations, and began exporting heavy-duty parts to European and Middle Eastern markets.
Integration of smart simulation software and digital management processes. Focused on wear-resistant alloys and reduced carbon footprint casting solutions.
Providing specialized systems designed for critical global sectors.
Designed for high-temperature and crushing operations. From slag handling pots to major structural frames, we design components to withstand heavy dynamic stress.
We manufacture long-lasting components for SAG and ball mills, jaw crushers, and primary gyratory systems to maximize structural life under high wear conditions.
Utilizing carbon steel, low-alloy steel, and high-manganese variants, we cast large-tonnage machine components tailored to customized engineering drawings.
The continuous shift toward ultra-large processing machinery (e.g., 60-110, 62-75, and 60-89 size gyratory models) demands higher performance from casting technology. Our research team focuses on three main developments:
We aim to enhance the durability of high-impact crushers. Standard manganese steel work-hardens under high stress. By refining the carbide distribution and controlling grain sizes, we ensure that wear parts maintain tough interiors while developing extremely hard outer surfaces during operation.
Ensuring clear communication, precise engineering, and quality-controlled delivery.
Project requirements collection, technical specification sheet reviews, and operational objective definitions.
Providing customized material selections, structure revisions, and detailed design models to optimize performance.
Final technical sign-offs, drawing verification, and commercial contract finalization.
In-house production, mold creation, steel melting, casting, and controlled cooling processes.
Pre-shipment inspections: NDT, dimensional testing, and surface quality assessments.
Secure crating, anti-rust treatments, and containerized global shipment coordination.
Expert installation guidance, alignment checks, and setup assistance.
Operational training and preventative maintenance schedules delivered to your team.
Prompt supply of replacement wear parts and technical engineering updates.
Expert answers regarding materials, manufacturing capabilities, and quality controls.
For major structural parts like the top and bottom shells, we recommend high-strength carbon steels (e.g., ASTM A27 or equivalent) which offer structural stability and resist cracking. For inner wear liners, we utilize high-manganese alloys (Mn13Cr2, Mn18Cr2, or Mn22Cr2) to maximize impact-hardening properties during crushing operations.
We use a combination of computerized solidification modeling (Magmasoft) and strict non-destructive testing (NDT). After thermal processing, all critical load zones undergo Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and Liquid Penetrant testing to verify integrity before machining.
Yes. The majority of our heavy castings are produced to custom engineering drawings. Our engineering division reviews your dimensional configurations and material properties, converting drawings into digital molds for casting.
Lead times depend on casting complexity and size. Generally, the casting, heat treatment, and precision machining cycle for major components (above 30 tons) requires 60 to 90 days. We provide regular manufacturing updates throughout this process.
