Product Overview
Welcome to Henan San Kuang Machinery Technology Co., Ltd. Our Composite Crusher Bimetallic Hammer is specifically engineered for high-efficiency crushing of limestone and gypsum, delivering exceptional wear resistance and a remarkably long serving life. With over a decade of manufacturing expertise (since 2014) and a dedicated factory spanning 10,000–30,000 square meters, we produce hammers that meet the demanding requirements of cement plants, quarries, and mining operations worldwide. The bimetallic design combines a tough, impact-resistant core with a super-hard wear layer, drastically reducing downtime and replacement costs. Whether you operate an impact crusher or hammer crusher, this product is your reliable solution for sustained productivity.
Key Features & Technical Specifications
- Bimetallic Structure – The working surface is cast from high-chromium alloy (HRC 58-62) while the base is made of mild steel, providing a perfect balance of hardness and toughness. This structure resists severe abrasion from limestone and gypsum, while preventing breakage under heavy impact.
- Extended Service Life – Field tests show our hammers last 2–3 times longer than conventional high-manganese steel (Mn13) hammers under identical crushing conditions. This reduces the frequency of shutdowns for hammer replacement.
- Optimized for Limestone & Gypsum – The chemical composition and heat treatment are tailored for materials with moderate hardness (Mohs 3–4 for gypsum, 3–4 for limestone). The hammer resists abrasive wear and maintains sharp edges for consistent crushing efficiency.
- Customizable Dimensions & Weight – We offer hammers compatible with major crusher brands (e.g., Hazemag, SBM, Metso, Sandvik) and can produce custom dimensions and weight according to your specific rotor design. Contact our engineering team for a tailored solution.
- Strict Quality Control – Every batch undergoes hardness testing, chemical analysis, and impact toughness verification. Our ISO9001-certified processes ensure consistent quality.

Advantages for Your Operation
By choosing our bimetallic hammer, you gain:
- Reduced Operating Costs – Longer wear life means fewer purchases and less labor for installation. Annual hammer consumption can decrease by 40–60% compared to standard manganese steel.
- Higher Crushing Efficiency – The sharp, hard edge maintains a consistent gap between hammer and breaker plate, resulting in a more uniform product size and lower recirculation load.
- Lower Energy Consumption – With optimized geometry, the hammer requires less energy to crush each ton of material, improving the overall efficiency of your crusher.
- Minimized Downtime – Thanks to impact toughness and crack resistance, hammer breakage is rare. Your production line runs smoothly for longer uninterrupted periods.
- Global Logistics Support – We ship from four major Chinese ports (Shanghai, Lianyungang, Qingdao, Tianjin) and have exported to North America, South America, Europe, Africa, Oceania, the Middle East, and Asia. Our experienced logistics team ensures timely delivery.

Frequently Asked Questions
-
Q: What is the typical lifespan of this bimetallic hammer compared to traditional manganese steel hammers?
A: Under normal conditions crushing limestone (Mohs 3-4) and gypsum (Mohs 2-3), our bimetallic hammer lasts 2 to 3 times longer than conventional Mn13 hammers. For example, in a cement plant processing 200 t/h of limestone, a Mn13 hammer may need replacement every 150 operating hours, while our composite hammer can last 400+ hours. -
Q: Can the hammer be customized for different crusher models?
A: Yes, we offer full customization. Please provide the original hammer drawing or dimensions, rotor specifications, and required weight. Our engineering team will design a bimetallic hammer that fits your specific crusher, ensuring proper balance and performance. -
Q: Is there a minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 50 pieces. For custom sizes, the MOQ is 100 pieces. However, we can accommodate smaller trial orders for first-time customers. Contact our sales team for details. -
Q: What is the warranty period for your hammers?
A: We provide a 12-month warranty from the date of shipment against manufacturing defects (e.g., premature cracking, excessive wear due to material quality issues). Normal wear and improper use are not covered. We will replace defective hammers free of charge or issue a credit. -
Q: Do you offer samples for testing before bulk order?
A: Absolutely. We can provide sample hammers (1–5 pieces) at a reasonable cost, with the sample fee deducted from the first bulk order. Shipping costs are borne by the buyer. This allows you to verify the performance in your own crusher. -
Q: How do you ensure consistent hardness and quality across batches?
A: We follow strict ISO9001 procedures. Each batch is cast using controlled melting and heat treatment processes. Statistical sampling is performed: at least 5% of each batch is tested for hardness, impact toughness, and chemical composition. A certificate of analysis is provided with each shipment. -
Q: Can these hammers be used for crushing other materials like coal or shale?
A: Yes, our bimetallic hammer is versatile and suitable for materials with similar abrasiveness and impact characteristics, such as coal, shale, soft to medium-hard ores, and even some construction waste. However, for very abrasive materials like quartzite or granite, a different grade (e.g., ceramic composite) may be recommended. Consult our technical team for material-specific advice. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and other negotiable terms for long-term partners. For first-time orders, 100% T/T in advance may be required for small amounts.
