What Material Is Used for Crusher? A Complete Guide to Crusher Materials and Selection

When buyers search for “what is the material us for crusher,” they usually want to know two things: what materials crushers are built from, and what materials crushers can process. This guide answers both questions with practical, SEO-friendly detail—covering wear parts, structural steel, and the raw materials different crusher types handle best.

Quick Answer: What Material Is Used for a Crusher?

Crushers are typically made from high-manganese steel (Mn13, Mn18, Mn22), high-chrome cast iron, alloy steel, carbon steel, and wear-resistant composite materials. The crushing chamber and wear parts (jaw plates, blow bars, cone liners, hammers) use manganese or chrome alloys, while the frame and housing use welded carbon steel or cast steel. The right material depends on the crusher type, the feed material, and the abrasiveness of the application.

Materials Used to Build Crushers (Construction Materials)

1. High-Manganese Steel (Mn13, Mn18, Mn22)

High-manganese steel is the most common material for jaw plates, cone liners, and impact aprons. It work-hardens under impact, so its surface gets harder as it crushes rock—ideal for abrasive, high-impact duties like granite, basalt, and ore.

2. High-Chrome Cast Iron

High-chrome alloys (Cr15–Cr26) offer excellent abrasion resistance for hammer crushers and blow bars in secondary crushing. They suit less impact-intensive but highly abrasive feeds such as limestone and clinker.

3. Alloy Steel and Carbon Steel

Frames, shafts, and structural components are usually welded carbon steel (Q235/Q345) or cast alloy steel. These provide strength, weldability, and cost efficiency for the crusher body.

4. Wear-Resistant Composite and Ceramic Materials

Ceramic-reinforced composites and hardfacing overlays are used on high-wear zones to extend service life in extreme abrasive conditions.

5. Ductile Iron and Cast Steel

Used for housings, bearing seats, and pulleys where toughness and vibration damping matter.

Materials That Crushers Process (Feed Materials)

Different crushers handle different feeds:

• Jaw crushers: granite, basalt, limestone, river stone, slag, concrete, ore—primary crushing of hard and medium-hard rock.
• Cone crushers: hard and abrasive ores, granite, basalt, pebbles—secondary and tertiary crushing.
• Impact crushers: limestone, dolomite, shale, gypsum, coal—medium-hard, less abrasive materials.
• Hammer crushers: limestone, coal, chalk, gypsum—brittle materials.
• VSI sand makers: pebbles, quartz, basalt—shaping and sand production.

How to Choose the Right Crusher Material

Match the wear-part material to your application:

1. High impact + high abrasion → high-manganese steel (Mn18/Mn22).
2. High abrasion, lower impact → high-chrome alloy.
3. Mixed feed with metal contamination → manganese steel with tough core.
4. Fine output and shaping → chrome or ceramic-composite wear parts.

Also consider feed size, moisture, throughput, and cost per ton—not just the initial part price.

FAQ

Q: What is the best material for crusher jaws?
A: High-manganese steel (Mn18) is the standard for jaw plates because it work-hardens under load and resists impact abrasion.

Q: Can a crusher crush wet or sticky material?
A: Yes, but sticky feeds may require jaw or cone crushers with special liners; impact and hammer crushers can clog.

Q: How long do crusher wear parts last?
A: Service life depends on material, feed abrasiveness, and settings—manganese liners may last weeks to months, while chrome parts last longer in low-impact duty.

Conclusion

The material used for a crusher falls into two categories: construction materials (high-manganese steel, high-chrome iron, alloy and carbon steel) and processable feed materials (rock, ore, concrete, coal, and more). Choosing the right wear-part material for your feed and application is the key to lower cost per ton and longer equipment life.
