Crusher Spare Parts: Types and Leading Chinese Manufacturers

Crusher spare parts are critical consumables that ensure the continuous operation and performance of crushing equipment. These parts are subject to intense wear, abrasion, and impact. Using high-quality, properly fitted spare parts is essential for maintaining crushing capacity, product shape, and minimizing unplanned downtime. The aftermarket for crusher parts is vast, with many specialized manufacturers in China supplying both OEM-equivalent and generic parts.

1. Major Categories of Crusher Spare Parts

Parts vary by crusher type (Jaw, Cone, Impact, etc.) but generally fall into these core wear part categories.

• Wear Liners & Jaws:
  • Jaw Crusher: Jaw plates (fixed and movable).
  • Cone Crusher: Mantle and concave (bowl liner).
  • Impact Crusher: Blow bars (hammers) and impact plates/apron liners.
  • Material: High Manganese Steel (Mn14%, Mn18%, Mn22%), High Chrome Iron, Composite alloys.
• Internal Mechanical Parts:
  • Eccentric bushes/sleeves, thrust bearings, main shaft, head centers, socket liners, seals, and gaskets.
  • These ensure the precise mechanical movement of the crusher.
• External & Structural Parts:
  • Frame parts, toggle plates, tension rods/springs (for jaw crushers), rotors (for impact crushers), belt pulleys, guards.
• Fasteners & Miscellaneous:
  • High-strength bolts, nuts, wedges, and lock nuts used to secure wear liners and other components.

2. Leading Chinese Brands for Crusher Spare Parts

China is a global hub for crusher part manufacturing, with companies ranging from OEM-affiliated factories to independent foundries specializing in wear parts.

3. Key Considerations When Selecting Crusher Parts

• Compatibility & Quality: Parts must match the OEM specifications for dimensions, tolerance, and material grade. Inferior materials lead to rapid failure.
• Material for the Application: Choose manganese steel for high-impact/compression (jaws, cones) and high-chrome iron for high-abrasion/low-impact (blow bars for abrasive rock).
• Cost vs. Performance: Cheaper parts may have lower upfront cost but often result in shorter life and higher downtime cost per ton crushed.
• Supplier Reliability: Choose established suppliers with proven quality control, traceability, and technical support.
• Availability & Lead Time: A reliable supplier should have good stock or short manufacturing lead times to minimize your inventory holding.

Conclusion: The crusher spare parts ecosystem is extensive. For OEM-equivalent quality, manufacturers like Shenyang Sanland (for Metso) and Zhuji Yinfeng are leading choices for wear parts. For critical mechanical components, precision manufacturers like Maanshan Shi Boda are essential. For cost-effective wear parts in less demanding applications, numerous foundries in Ningbo, Wuyi, and Hebei offer solutions. The key is to match the part's quality and material to the specific crushing application to optimize the total cost per ton of material processed.
