Jaw Crusher

The Pyramids Jaw Crushers Series is designed for superior performance, durability, and reliability in a wide range of crushing applications. These crushers are well-suited for crushing materials of all hardness levels, offering exceptional efficiency with minimal operating costs and easy maintenance. They are available in various configurations, including mobile units, fixed steel legs, fixed concrete legs, and skid-mounted chassis.

Primary and Secondary Crushing

While primarily used in the primary crushing stage, the jaw crusher design allows for secondary crushing applications, providing flexibility and versatility to meet diverse requirements.

Features and Components

1. Crushing Mechanism

The crushing process is powered by a high-pressure mechanical system. The elliptical movement of the movable jaw and the narrowing angle between the fixed and movable jaws grip and compress the material efficiently.

• Key Advantages:
  • High flywheel speed for increased crushing force.
  • Optimized jaw gripping angle for enhanced material handling.
  • Precision-engineered geometry between the pitman and back block ensures controlled and efficient pressure application.

2. Jaw Opening Adjustment

The jaw opening can be quickly and easily adjusted to achieve the desired product size. This adjustment is made by adding or removing shim plates at the back of the adjustment block, supported by a hydraulic system for faster setup.

3. Jaw Plates

Both fixed and movable jaws are manufactured from manganese steel casting, ensuring high resistance to wear and breakage. The back surfaces are precision-processed to prevent damage and ensure a secure fit.

4. Crusher Shaft

The shaft is precision-machined from forged steel to provide durability and strength. The eccentricity of the shaft enables the elliptical movement of the movable jaw.

• Bearings are spherical roller bearings, grease-lubricated and protected by a labyrinth system to prevent contamination.

5. Safety Plate

A cast iron safety plate protects the drive system from potential damage caused by unintentional metal objects. The plate is engineered to break under overload conditions, preventing harm to the machine.

6. Durable Body

The crusher body features a robust welded design, treated with heat to relieve stress and ensure structural integrity.
