GRAU JAW CRUSHERS
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.
WHAT IS A JAW CRUSHER?
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.
JAW CRUSHER ADVANTAGES
- 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.
