Crusher hammers are the core wear parts of hammer crushers, achieving material crushing through high-speed rotation. Their performance directly impacts equipment efficiency, energy consumption, and maintenance costs. A good hammer must balance wear resistance, impact resistance, and toughness — properties closely tied to material selection, structural design, and manufacturing processes.
What Makes a “Good Hammer”?
High Wear Resistance
The hardness should exceed that of the material being crushed (generally ≥0.8x the material hardness). For example, high-chromium iron hammers with HRC 58–62 are ideal for high-hardness materials like quartz and basalt.
Excellent Impact Toughness
The hammer must withstand repeated impact without fracturing. High-manganese steel hammers, for instance, work-harden under impact, making them suitable for high-impact applications (e.g., metallurgy, mining).
Optimized Structural Design
Shape and structure must balance hardness and toughness. Bimetal composite hammers — with a high-chromium iron head and low-alloy steel shaft — combine wear resistance with fracture tolerance, ideal for hard and abrasive materials.
Material Adaptability
Medium/low abrasiveness (e.g., limestone): Forged hammers (e.g., 65Mn steel) offer cost-effectiveness.
Highly abrasive materials (e.g., iron ore): High-chromium or bimetal hammers perform better.
Long Service Life & Cost Efficiency
Premium hammers reduce replacement frequency. SHANVIM’s bimetal hammers, for example, last 3–4x longer than traditional high-manganese steel hammers, lowering overall operating costs.
SHANVIM’s Core Advantages
Bimetal Composite Technology
Liquid-liquid fusion ensures 99% bond strength between the high-chromium head (e.g., Cr26) and alloy steel shaft, preventing fracture and spalling. Elements like vanadium, titanium, and rare earths refine grain structure for enhanced wear resistance.
Advanced Heat Treatment
Quenching at 1100°C + tempering at 600°C yields hardness up to HRC 62–65 while maintaining toughness, significantly extending service life.
Diverse Material Options
High-manganese steel (Mn13Cr2MoNi), high-chromium iron (Cr20/Cr26), and alloy steel cover a broad range of material hardness and abrasiveness.
Customization Support
Drawing, samples, or on-site measurements can be used to tailor hammers to specific dimensions and operating conditions.
Proven Performance
Bimetal hammers show over 50% lower wear rates when crushing high-silica limestone or coal gangue, while also improving output uniformity.
Typical Applications
Building Materials: Limestone, cement clinker
Mining & Metallurgy: Iron ore, quartzite
Green Production: SHANVIM hammers in PCH ring hammer crushers reduce dust and energy use, supporting eco-friendly operations.
Conclusion
A “good hammer” balances material, design, and process. SHANVIM delivers high wear resistance, long service life, and operational economy through bimetal technology, optimized alloys, and custom solutions — particularly suited for hard and abrasive materials. Their hammers offer reduced downtime, stable performance, and lower overall cost, making them a top choice for mining, construction, and industrial crushing applications.
