Experience Superior Crushing Efficiency with Our Bimetallic Hammer – Engineered for Composite Crushers
Henan San Kuang Machinery Technology Co., Ltd., established in 2014 and spanning 10,000–30,000 square meters, has dedicated over a decade to advancing wear-resistant solutions for the global mining and aggregate industry. Our Bimetallic Hammer for Composite Crusher integrates a premium tungsten carbide insert with a hardness of HRC68, delivering exceptional resistance against abrasive and impact-heavy materials. With an annual export value of US$2.5–5 million and a workforce of 51–100 skilled professionals, we consistently supply high-performance crusher hammers to markets across North America, South America, Europe, Southeast Asia, Africa, and Oceania. This product is the result of rigorous R&D, precision casting, and strict quality control under our ISO9001, ISO14000, and OHSAS18001-certified systems.
Key Features & Technical Specifications
- Dual-Material Synergy: The hammer body is manufactured using a bimetallic casting process – a tough, impact-resistant low-carbon steel base combined with a high-chrome alloy wear layer. The carbide insert (HRC68) is precisely positioned at the striking face for maximum abrasion resistance.
- Unmatched Hardness & Toughness: The carbide insert achieves HRC68 hardness, while the base material maintains excellent toughness to withstand repeated high-impact forces without cracking. This combination ensures a balanced compromise between wear life and structural integrity.
- Optimized Geometry: Each hammer is designed with an elongated striking edge and a tapered body to improve material penetration and reduce energy consumption. Custom profiles are available upon request to suit different crusher models and feed sizes.
- Consistent Performance: All hammers undergo heat treatment and aging processes to stabilize microstructure, resulting in uniform hardness and predictable wear patterns.
| Parameter | Value |
|---|---|
| Carbide Insert Hardness | HRC 68 ± 2 |
| Base Material Impact Toughness (Ak) | ≥ 80 J/cm² |
| Wear Layer Hardness (High Chrome) | HRC 58–62 |
| Maximum Operating Temperature | ≤ 250°C |
| Weight Range (single piece) | 10 kg – 150 kg (custom) |
| Crusher Type Compatible | Composite/Impact/Hammer crushers |
Customer Benefits & Operational Advantages
- Extended Service Life: The carbide insert can last 2–3 times longer than traditional manganese steel hammers under abrasive conditions, reducing downtime for replacements.
- Lower Total Cost of Ownership: Although initial investment may be higher, the reduced frequency of changeovers and lower labor costs result in significant savings over the crusher’s lifespan.
- Improved Crushing Efficiency: The sharp, wear-resistant edge maintains consistent gap dimensions, stabilizing product output and minimizing fines generation.
- Versatility: Suitable for crushing limestone, river gravel, basalt, cement clinker, coal, and other medium-hard to hard materials.
- Easy Installation: Holes and mounting dimensions are machined to tight tolerances (ISO H7) for quick fitment on most OEM and aftermarket rotors.

Frequently Asked Questions (FAQ)
-
Q: Is the HRC68 hardness guaranteed for the entire hammer?
A: No, the HRC68 rating applies specifically to the tungsten carbide insert. The high-chrome wear layer is HRC58–62, and the steel base is softer for impact resistance. This design provides the optimum balance between wear and toughness. -
Q: Can I use this hammer for limestone with high silica content?
A: Yes, the carbide insert is highly effective against abrasive silica. Many clients in the cement industry use it for limestone containing 5–15% free silica. -
Q: What is the typical lead time and minimum order quantity?
A: Standard lead time is 15–20 days after order confirmation. MOQ is 10 pieces, but we can accommodate smaller trial orders for first-time customers. -
Q: How do I know which weight and size to order?
A: Please provide your crusher model, rotor diameter, and hammer pitch. Our engineers will recommend the optimal geometry or supply custom drawings within 3 working days. -
Q: Does the carbide insert come pre-brazed or do I need to install it?
A: The insert is factory-brazed into the hammer head using a high-temperature silver-copper alloy. It is ready for immediate installation. -
Q: What certification do you have for quality assurance?
A: Our company holds multiple certificates including ISO9001, ISO14000, OHSAS18001, and others like SA8000 and TL900. Product-specific test reports are available upon request. -
Q: Can you provide a sample for testing before bulk order?
A: Yes, we offer sample hammers at production cost plus freight. We recommend testing 2–4 pieces to evaluate performance in your actual operating conditions.
