GRAU Jaw Crushers can process all kinds of materials, from soft sedimentary rock to hardest granite or basalt. High quality materials combined with excellent design provide long service life in heavy-duty applications.



A perfect all-round versatile machine capable of crushing all kinds of materials, from soft sedimentary rock to hardest granite or basalt. Excellent design provides long service life even in the most challenging applications.



Jaw Crusher is a type of rock processing machine that breaks rocks by compressing them between two plates, called jaws. One of the jaws is fixed to the crusher body and the other jaw is moving. You can mostly see Jaw Crushers in primary crushing stages as they perform very well at reducing the size of large, hard and abrasive material lumps into easier to process pieces, but secondary jaw crushers are also fairly common.



  • Efficiency: Jaw Crushers are very efficient at reducing the size of even the hardest material.
  • Versatility: Jaw Crushers can handle a wide variety of materials, ranging from soft sedimentary rocks or RAP (Reclaimed Asphalt Pavement) to the hardest granite and basalts.
  • Low Wear: Jaw Crushers show less wear compared to impact crushers.
  • Low Fines: Jaw Crushers produce very low amount of fines and dust.

    Unique Operational Advantages
    GRAU Jaw Crushers come with many operational advantages. Jaw grabbing angle provides more efficient crushing, high flywheel speeds increase the momentum and crushing force while easy to operate adjustment systems allow for easier operation and maintenance.
  • Interchangeable Jaw Plates
    Upper and lower jaw plates are interchangeable while the top of the pitman is protected with a removable plate. Rear surfaces of the jaw plate seats are protected by lead sheets which reduce the surface imperfections and prevent the jaws from damage and premature breaking.

    Hydraulically Assisted CSS Adjustment
    All GRAU Jaw Crushers are equipped with Hydraulically Assisted CSS Adjustment Mechanism. It is very easy to change the CSS on the go, depending on your requirements.
Larger Models are Equipped with Buffers
Larger models of GRAU Jaw Crushers operate on rubber buffers that minimize the vibrations on the chassis both horizontally and vertically.
Hydraulic Self-Adjusting Motor Base
This system automatically adjusts the belt tension that may have changed in different weather condition and ambient temperatures.
