Jaw Crusher Parts

① Jaw Plates (Fixed & Movable Jaws)

1> Function: The primary crushing surfaces that compress and break down rocks.

2> Material: High manganese steel (Mn13, Mn18, Mn22), alloy steel, or tungsten carbide for extreme wear resistance.

3> Applications:

Granite, basalt, iron ore crushing

Quarrying, mining, recycling

② Toggle Plate

1> Function: Protects the crusher from overload damage by acting as a safety fuse.

2> Material: Cast iron or alloy steel for durability.

③ Toggle Seat

1> Function: Supports the toggle plate and ensures smooth jaw movement.

2> Material: Hardened steel or bronze for reduced friction.

④ Pitman (Eccentric Shaft Assembly)

1> Function: Transmits motion from the motor to the movable jaw.

2> Material: Forged steel (SAE 1045) with precision machining.

⑤ Bearings

1> Function: Supports the eccentric shaft for smooth rotation.

2> Type: Spherical roller bearings (e.g., SKF, NSK) for heavy loads.

⑥ Cheek Plates (Side Liners)

1> Function: Protects the crusher frame from wear caused by material impact.

2> Material: High manganese or AR steel.

Key Features & Advantages

• Extended Wear Life

Manganese steel jaws withstand extreme abrasion (2-3x longer than standard steel).

Precision-machined parts ensure proper fit and reduce downtime.

• Customizable Designs

Jaw plate profiles: Smooth, corrugated, or sharp teeth for different materials.

Bearing options: Standard, heavy-duty, or sealed for harsh environments. 

• Improved Crushing Efficiency

Optimized cavity design increases throughput by 15–20%.

Reduced energy consumption with balanced pitman assembly.

• Easy Replacement & Maintenance

Modular design allows quick jaw plate changes.

Interchangeable parts compatible with major brands (Metso, Sandvik, Terex, etc.).

①Mining & Ore Processing

Parts Used: Jaw Plates (Mn18Cr2), Pitman, Bearings

Materials Crushed:

Iron Ore, Gold Ore, Copper Ore – High-abrasion-resistant manganese steel jaws withstand heavy impact.

Bauxite, Nickel Ore – Corrugated jaw profiles improve grip for efficient crushing.

Key Benefit:

* Extended wear life in high-tonnage mining operations.

② Quarrying & Aggregates

Parts Used: Cheek Plates, Toggle System, Jaw Plates (Smooth/Corrugated)

Materials Crushed:

Granite, Basalt, Limestone – Hard rock crushing with optimized cavity designs.

Gravel, Sandstone – Smooth jaw plates produce uniform aggregate sizes.

Key Benefit:

* Reduced recirculation load with precise crushing profiles.

③ Recycling & Demolition

Parts Used: AR Steel Jaw Plates, Heavy-Duty Bearings

Materials Crushed:

Concrete, Asphalt, Brick – AR400 steel resists impact from rebar and debris.

Construction Waste – Reinforced toggle plates prevent overload failures.

Key Benefit:

* Lower maintenance costs in abrasive recycling environments.
