jaw crusher plates material

The material used for jaw crusher plates depends on factors like application, wear resistance requirements, and cost. Common materials include:

1. Manganese Steel (Mn14, Mn18, Mn22)
– Most common material due to its excellent work-hardening properties.
– Grades:
– Mn14%: Standard for moderate crushing conditions.
– Mn18%: Better wear resistance for tougher applications.
– Mn22%: Highest durability for highly abrasive materials.
– Hardens under impact, extending lifespan.

2. High Chromium Cast Iron (HCCI)
– Offers superior abrasion resistance but is more brittle than manganese steel.
– Used in highly abrasive environments (e.g., granite, quartz).

3. Alloy Steel (TIC Insert Plates)
– Reinforced with titanium carbide (TiC) inserts for extreme wear resistance.
– Longer lifespan but higher cost.

4. Stainless Steel
– Used in corrosive environments (e.g., chemical or marine applications).
– Less common due to lower hardness compared to manganese steel.

5. Composite Materials
– Some manufacturers use layered or hybrid materials combining toughness and wear resistance.

Selection Factors:
– Material Being Crushed (abrasive rocks require harder plates).
– Operating Conditions (impact vs. abrasion).
– Cost vs. Lifespan Trade-off.

For most standard applications (granite, basalt, concrete), manganese steel (Mn18%) is preferred due to its balance of durability and cost-effectiveness.
