Cone Crusher Mantle and ConcaveHigh Manganese Steel Solution for Mining and Quarry

Mantle and concave are the core wear parts of cone crushers.
They are widely used in mining and quarry production lines,
where stable crushing performance and long service life are critical.

Working Principle

In a cone crusher, the mantle moves against the concave
to crush material continuously.

Material is compressed, sheared, and broken
between the moving and fixed liners.

The shape, material, and fitting accuracy
of mantle and concave directly affect:

 Crushing efficiency
 Product size stability
 Equipment safety

Typical Working Conditions

Cone crushers are mainly used for medium to hard materials:

 Granite
 Basalt
 Iron ore
 Quartz

These materials create strong impact and abrasion,
which place high demands on wear parts.

Common Problems in Mantle and Concave

1. Uneven Wear

 Wear is not uniform across the liner surface.
 This is usually caused by improper feeding
 or uneven material distribution.

Solution

 Optimize feeding system
 to ensure even material flow.

 Use high manganese steel
 with stable work hardening performance.

2. Short Service Life

 Low quality material or poor heat treatment
 can lead to rapid wear.

 Frequent replacement increases downtime
 and production cost.

Solution

 Use Mn13Cr2 Mn18Cr2 or Mn22Cr2 materials.

 Control chemical composition
 and ensure proper heat treatment process.

3. Cracking or Breakage

 Often caused by internal defects
 or improper microstructure.

 Coarse grains or carbide networks
 increase brittleness.

Solution

 Strict metallographic control
 to ensure uniform austenite structure.

 Refined grain structure improves toughness
 and impact resistance.

4. Installation Problems

 Loose fitting or inaccurate dimensions
 can lead to abnormal stress and failure.

Solution

 Ensure precise machining
 and strict dimensional inspection.

 Guarantee proper fitting
 between mantle concave and crusher frame.

Material Options

We provide multiple material solutions
based on working conditions:

 Mn13Cr2
 Mn18Cr2
 Mn22Cr2
 High chromium cast iron
 Alloy steel
 Composite liners with ceramic insert

High manganese steel is the most commonly used.

Under impact and pressure,
the surface hardens during operation,
which significantly improves wear resistance.

Casting and Process Control

We focus on full process control
from melting to final inspection.

 Chemical composition control
 ensures correct Mn C and Cr ratio

 Resin sand casting
 improves dimensional accuracy
 and surface quality

 Pouring temperature control
 around 1550 to 1600 degrees
 ensures better internal structure

 Heat treatment water quenching
 forms stable austenite structure

Quality Control

We rely on real inspection data:

 Spectrometer testing
 for chemical composition

 Metallographic testing
 for internal structure

 Hardness testing
 to verify heat treatment stability

 Dimensional inspection
 to ensure proper installation

Performance Improvement

High quality mantle and concave
can significantly improve:

 Service life
 Production stability
 Crushing efficiency
 Cost per ton

Even if liners look similar,
their performance can differ greatly
due to material and process control.
