Product Overview

Qirun supplies Mn18Cr2 manganese steel jaw plates for quarry crushers processing granite, basalt, and other hard rock aggregates.

Manufactured from impact-resistant high manganese steel, these fixed and swing jaw plates combine toughness with work-hardening capability under suitable crushing loads. Their toothed surfaces help grip and fracture abrasive rock during primary crushing operations.

Qirun supports custom jaw plate profiles, casting dimensions, and OEM replacement requirements based on crusher models, technical drawings, and material specifications.

Key Features of Mn18Cr2 Quarry Jaw Plates

1. Impact Toughness for Hard Rock Crushing

Mn18Cr2 high manganese steel is used for wear components exposed to repeated impact and compressive loading.

This material provides a combination of toughness and work-hardening capability for demanding primary crushing applications.

It is suitable for selected quarry operations processing hard rock such as granite and basalt.

2. Work-Hardening Wear Resistance

High manganese steel can develop increased surface hardness under repeated impact and compression.

This work-hardening behavior helps the crushing surface resist wear while maintaining a tough underlying structure.

Actual performance depends on rock abrasiveness, crushing load, alloy composition, heat treatment, and equipment conditions.

3. Customized Tooth Profiles

Jaw plate tooth geometry influences material gripping, crushing chamber behavior, and wear distribution.

Qirun supports customer-specified profiles based on equipment drawings.

Customization can include:

  • Coarse crushing teeth

  • Corrugated jaw plate surfaces

  • Tooth pitch and height

  • Plate thickness and dimensions

  • Mounting and contact surfaces

  • Custom replacement profiles

4. Fixed and Swing Jaw Plate Options

Qirun supports fixed and movable jaw plate requirements for compatible quarry crushers.

The fixed jaw plate provides the stationary crushing surface, while the swing jaw plate applies compressive force through the moving jaw assembly.

Both components require suitable dimensions, tooth geometry, and material properties for correct operation.

5. Optional TIC-Reinforced Construction

Titanium carbide (TIC) inserts may be incorporated into selected manganese steel jaw plate designs to improve localized abrasion resistance.

The reinforcement arrangement must be developed according to the component geometry and operating conditions.

TIC-reinforced jaw plates should be specified separately from standard Mn18Cr2 castings.

Mn18Cr2 Manganese Steel Material Properties

Mn18Cr2 is a chromium-alloyed high manganese steel grade used for impact-resistant crusher wear parts.

Its material characteristics are influenced by manganese and chromium content, carbon content, and appropriate heat treatment.

Higher manganese content does not automatically guarantee longer service life.

Wear performance depends on the full alloy specification, heat treatment, rock characteristics, and crushing conditions.

Quarry Crushing Applications

Granite Quarry Crushing

Granite contains hard mineral constituents that can create severe abrasive wear on crusher components.

Mn18Cr2 jaw plates provide impact-resistant crushing surfaces for compatible jaw crushers handling suitable granite feed.

Tooth profiles and material specifications should match the actual crusher configuration.

Basalt Aggregate Production

Basalt crushing involves repeated impact and compression of strong rock materials.

High manganese steel jaw plates are used in suitable primary crushers to withstand these mechanical loads.

Their work-hardening properties can be beneficial when the operating stresses are sufficient.

Hard Rock Mining

Primary jaw crushers are used in selected mining operations to reduce large ore and hard rock feed before downstream processing.

Mn18Cr2 jaw plates offer a replacement casting option for compatible equipment.

Construction Aggregate Quarries

Jaw crushers are used in aggregate production plants to reduce large stone into manageable material sizes.

Fixed and swing jaw plates form the working crushing surfaces and require periodic replacement according to their wear condition.

Frequently Asked Questions

What are Mn18Cr2 quarry jaw plates?

Mn18Cr2 quarry jaw plates are manganese steel wear components used in compatible jaw crushers for processing granite, basalt, and other suitable hard rock aggregates.

Why is Mn18Cr2 used for quarry jaw plates?

Mn18Cr2 provides impact toughness and work-hardening capability, making it suitable for selected crushing applications involving repeated impact and compression.

Can Mn18Cr2 jaw plates be used for granite and basalt?

Yes. They may be suitable for granite and basalt crushing when the jaw plate design, crusher configuration, and operating conditions are appropriate.

What is the difference between Mn18Cr2 and Mn22Cr2?

Mn22Cr2 has a higher nominal manganese content. However, actual wear performance depends on alloy composition, heat treatment, crushing load, and rock abrasiveness.

Can Qirun manufacture custom tooth profiles?

Yes. Qirun supports jaw plate manufacturing based on customer drawings, tooth geometry, and component dimensions.

Are fixed and swing jaw plates available?

Qirun supports both fixed and swing jaw plate configurations for compatible crusher requirements.

Are TIC-reinforced jaw plates available?

TIC reinforcement is listed as an optional material design in Qirun's product information. Specific availability and reinforcement configurations should be confirmed during quotation.

Are these jaw plates compatible with C160 crushers?

The existing product listing identifies C160 as the model. Actual compatibility should be verified against the original part number, plate geometry, and mounting dimensions.

What information is required for a quotation?

Please provide the crusher model, jaw plate part number, dimensions, preferred material, tooth profile, feed rock type, and required quantity.
