Material Analysis Suggestions

Crusher liners are typically made from a variety of materials, each with different properties to suit different crushing applications and requirements. Here is a comprehensive analysis of the materials commonly used for crusher liners:

1. Manganese steel

Features:

Work hardening: Manganese steel liners harden under impact and become more wear resistant during use.

High toughness: Resists cracking and chipping, suitable for high impact applications.

Initial softness: Softer in initial state, causes faster wear before work hardening.

Variations:

Mn13: Commonly used for general applications.

Mn18: Standard grade, suitable for most aggregate and recycling applications.

Mn22: Higher manganese content results in better work hardening, ideal for hard rock applications.

2. High chromium cast iron

Features:

Excellent wear resistance: Ideal for handling highly abrasive materials such as silica sand and certain ores.

High hardness: Has excellent wear resistance.

Brittleness: More likely to crack when impacted, so less suitable for high impact applications.

Applications:

Best suited for low impact, steady feed environments where wear is a primary concern.

3. Alloy Steels

Features:

Higher Wear Resistance: Outperforms manganese steels, especially in finer crushing applications.

Good Strength and Hardness: Provides a balance of wear resistance and toughness.

Less Deformation: More resistant to deformation under extreme pressures than manganese steels.

Applications:

Suitable for a wide range of crushing applications, especially where the material is highly abrasive.

4. Ceramic Inlay/Composite

Features:

Extremely High Wear Resistance: Can significantly extend liner life in highly abrasive applications.

Tailored for Specific Wear Patterns: Can be customized to address localized wear.

Applications:

Used in specialized applications where extremely high wear resistance is required, but they are expensive and brittle.

Factors Influencing Material Selection

Material Being Crushed: Type, abrasiveness, hardness, size and moisture content of the feed material are key factors.

Crusher type and size: Different crushers (e.g. jaw, cone, impact) have specific material requirements.

Operating conditions: Ambient temperature, humidity, and dust levels can affect liner performance.

Budget: Cost considerations play a major role in material selection.
