Direct from Henan Hanhai Metallurgy Mining - Highly durable components engineered to survive extreme working conditions.
Cone crushing machinery has transitioned from mechanical spring-regulated assemblies to advanced, hydraulic compound systems. This shift is driven by the global demand for finer output gradations, higher energy efficiency, and reduced downtime. China's top manufacturers have pioneered this transition by utilizing heavy-duty castings and sophisticated alloys, enabling machinery to handle compressive strengths exceeding 350 MPa without structural degradation.
Modern engineering contracts require verification of material traceability and manufacturing standards. Global procurement officers prioritize suppliers who offer ISO9001 and CE-certified metallurgy. Our foundry handles heavy casting specifications including manganese steel linings, high-strength alloy steel mainframes, and stress-relieved casting structures that perform reliably in extreme temperatures ranging from -30°C to 45°C.
Operating as a premium metallurgy trade division, Henan Hanhai Metallurgy Mining International Trade Co., LTD integrates design, casting, and precision machining under a single operational chain. Our casting processes use digital simulation software to minimize gas pockets and slag inclusions, delivering structural castings that sustain the extreme cyclic fatigue loads of mining operations.
Henan Hanhai Metallurgy Mining International Trade Co., LTD is a leading foundry manufacturer in China, specializing in cast steel and cast iron parts. With advanced production lines and strict quality control, we supply durable castings for mining, metallurgy, power generation, and construction industries worldwide.
Our facility integrates advanced chemical analysis laboratories, non-destructive testing (NDT), ultrasonic testing (UT), magnetic particle testing (MT), and coordinate measuring machine (CMM) inspection stations. This ensures every stone cone crusher casting and heavy engineering part conforms to your exact drawing requirements.
Mission: To empower industry with precision casting and sustainable manufacturing excellence.
Vision: To be a trusted global foundry brand delivering high-quality steel and iron castings.
Optimizing production throughput and metallurgical durability in heavy-duty aggregate lines.
We deliver total industrial solutions. This covers critical primary systems like the PE and PEW European Type Jaw Crushers, transition systems involving PG Roller Crushers and custom impact designs, and final stage processing via our PY Spring Cone Crushers and PYF Compound variants. This seamless equipment flow ensures stable, continuous aggregate sizing.
Hanhai Casting's core strength is metallurgical chemistry. For cone crusher parts like mantles, bowl liners, and support sleeves, we control steel alloy compositions (Mn13Cr2, Mn18Cr2, Mn22Cr2) and implement advanced heat treatment programs to maximize tensile strength and hardness profiles, reducing component wear and operating costs.
Our new generation CZS and compound cone crushers utilize hydraulic dual-acting release cylinders. This allows uncrushable materials (such as tramp iron) to pass safely without damaging the machine. Integrated telemetry monitors power draw, lube pressure, and eccentric speed to prevent catastrophic failure.
Over 26 years of dedicated engineering and expansion in heavy-duty metallurgy.
Hanhai Casting was established with a focus on heavy steel and iron castings, laying a solid technical and production foundation.
Introduced advanced melting and molding technology, expanded production capacity, and served key mining and metallurgy sectors across China.

Integrated intelligent foundry systems and digital management, driving sustainable manufacturing and global customer partnerships.
Our testing and certification systems ensure zero-defect deliveries for global heavy mining projects.
To ensure structural components like the crusher support sleeve, bearing housing, and turbine cylinder can withstand thousands of hours of high-frequency impact loading, we enforce standard Quality Control Plans (QCP). Every major casting undergoes:
Supporting critical sectors with cast steel, cast iron, and complete mineral processing layouts.
Heavy-duty cast components designed for iron ore, copper ore, and gold mineral processing circuits, including crusher frames, main shafts, and slag ladles.
Castings for rotary kilns, support rollers, end caps, girth gears, and impact plate castings built to handle thermal expansion and heavy friction load profiles.
Industrial valve bodies, pump housings, support beams, and complex geometries manufactured from high-grade carbon and alloy steels for fluid systems.
Structured processes to ensure absolute specification alignment, trace manufacturing, and safe international delivery.

The choice depends on the properties of the material and the target aggregate structure. The PY Spring Cone Crusher utilizes a mechanical spring relief system. It is a reliable, cost-effective machine suited for medium-hard ores and traditional aggregate screening. It excels in environments where power grids are unstable, as its mechanical systems are straightforward to service.
Conversely, the CZS High-Efficiency Cone Crusher features hydraulic adjustments and dynamic overload protection. It is suited for secondary and fine crushing stages requiring high volume output and precise size control. The CZS design achieves higher throughput speeds, uses less energy per ton, and offers simple hydraulic clearing to reduce maintenance downtime when dealing with tramp iron.
The mantle and bowl liner are subject to high compressive stresses and abrasive sliding wear. The industry standard is Hadfield Manganese Steel, typically in the form of Mn13Cr2, Mn18Cr2, or Mn22Cr2.
Under impact loads, high-manganese steel work-hardens on its outer layer while maintaining a ductile core. This work-hardening behavior increases surface hardness from 200 HB to over 500 HB, protecting the component from abrasive wear. Adding chromium (Cr) increases the yield point and prevents the lining from stretching under pressure.
Our factory operates under strict ISO 9001:2015 and CE quality standards. Each casting receives a complete quality inspection documentation package, including:
- Material Test Report (MTR) verifying chemical analysis and mechanical values.
- Non-Destructive Testing (NDT) certificates, covering Ultrasonic (UT) and Magnetic Particle (MT) scans.
- Heat treatment charts documenting heating cycles, holding times, and cooling methods.
- Coordinate Measuring Machine (CMM) dimensional verification records compared directly to CAD designs.
Machined surfaces on large castings are vulnerable to salt-spray corrosion during ocean transport. We prevent this by applying specialized rust-preventative polymers and vacuum-sealing high-precision machined areas (like bearing bores and thread connections).
All shipments are loaded onto heavy-duty steel bases or into shock-absorbing wooden crates, anchored with heavy tension strapping to prevent shifting in transit.
