Crusher Rolling Mortar Wall

We manufacture high-performance Rolling Mortar Walls using high-manganese steel (Mn13, Mn18), high-chromium cast iron (Cr26, Cr28), and bimetal composites, ensuring superior longevity and cost-effective operation for cone, jaw, and hammer crushers.

Why Choose Our Rolling Mortar Walls?

1、Premium Material Selection for Maximum Wear Resistance

We utilize three advanced material types to meet different crushing demands:

High-Manganese Steel (Mn13, Mn18)

✔ Excellent work-hardening capability – Becomes harder under impact, improving wear resistance.

✔ Superior toughness – Ideal for high-impact crushing of hard rocks (granite, basalt).

✔ Long service life – Reduces replacement frequency in cone and jaw crushers.

High-Chromium Cast Iron (Cr26, Cr28)

✔ Exceptional abrasion resistance – Perfect for highly abrasive materials (quartz, iron ore).

✔ High hardness (HRC 58-62) – Maintains sharp edges longer for consistent crushing performance.

✔ Corrosion resistance – Suitable for wet or corrosive environments.

Bimetal Composite

✔ Combines toughness and hardness – Manganese steel base with chromium iron overlay.

✔ Optimized cost-performance ratio – Ideal for severe wear applications.

✔ Customizable wear zones – Reinforced protection in high-abrasion areas.

2、Precision Manufacturing for Reliable Performance

Advanced casting techniques ensure uniform material density and minimal defects.

Heat treatment optimization enhances hardness and impact resistance.

CNC machining guarantees precise dimensions for perfect crusher fit.

Non-destructive testing (NDT) verifies structural integrity before delivery.

3、Compatibility with Major Crusher Models

Our Rolling Mortar Walls are engineered for:

✔ Metso HP/GP Series Cone Crushers

✔ Sandvik CH/CS Series Cone Crushers

✔ Symons Cone Crushers

✔ Terex, Telsmith, and other OEM models

Key Features & Benefits

✅ Extended Service Life – 30-50% longer wear life than standard alternatives.

✅ Higher Crushing Efficiency – Maintains optimal geometry for consistent output.

✅ Reduced Downtime – Fewer replacements mean more production uptime.

✅ Cost Savings – Lower cost per ton crushed due to enhanced durability.

✅ Easy Installation – Precision-engineered for quick, hassle-free replacement.

Applications Across Crushing Equipment

Our Rolling Mortar Walls are widely used in:

Cone Crushers – Primary and secondary crushing of hard rocks.

Jaw Crushers – Heavy-duty crushing in mining and quarrying.

Hammer Crushers – Aggressive impact crushing for cement and aggregates.

Ideal for Processing:

Granite, Basalt, Iron Ore (High-manganese steel recommended)

Quartz, Abrasive Aggregates (High-chromium iron preferred)

Recycled Concrete, Asphalt (Bimetal composite for balanced wear resistance)

Material Selection Guide

High-Manganese Steel (Mn13, Mn18)

Best for high-impact crushing (e.g., jaw & cone crushers).

Work-hardens under load, improving wear resistance over time.

Typical hardness: HB 200-300 (up to HB 400 when work-hardened).

High-Chromium Cast Iron (Cr26, Cr28)

Ideal for highly abrasive materials (e.g., quartzite, slag).

Maintains high hardness (HRC 58-62) but less impact-resistant than manganese steel.

Recommended for fine crushing applications.

Bimetal Composite

Combines manganese steel's toughness with chromium iron's hardness.

Cost-effective for severe wear conditions.

Customizable wear zones for optimized protection.

Maintenance Tips for Longer Service Life

Regular Inspections – Check for cracks, uneven wear, or deformation.

Proper Alignment – Ensure correct installation to prevent premature failure.

Avoid Overloading – Stay within crusher capacity limits.

Monitor Feed Material – Remove oversized or tramp metal to reduce wear.

Timely Replacement – Replace before excessive wear damages other components.
