Stone crusher refers to equipment specially used for crushing large stones into stones. Common stone crushers include jaw crusher, impact crusher, impact crusher (sand making machine) and so on. These types of crushing equipment are widely used in stone crushing and stone processing, and each has its own advantages. Under different production requirements, different crushers can be selected.

The jaw crusher is also called Laohukou, because it is a crusher that simulates the movement of the two jaws of an animal to complete the material crushing operation. This equipment can be regarded as the most used equipment in stone crushing, because the big stone needs to be coarsely crushed by a jaw crusher. It has a large crushing ratio, high efficiency, and simple structure. It is suitable for crushing with a compressive strength below 320Mpa. Stone has great advantages in stone crushing.

The impact crusher appeared much later than the jaw crusher. It is the main fine crushing equipment, a new type of crusher designed on the basis of the jaw crusher. Counter-attack crushing can handle materials with a side length of 100-500 mm, and the pressure resistance can reach 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. The crushing process can be simplified, and the three-stage crushing can be turned into two-stage or one-stage crushing.

Impact crushers are generally called sand making machines, which play an irreplaceable role in various ore fine crushing equipment, and are currently effective, practical and reliable stone crushers. This equipment is suitable for artificial sand making of river pebbles, pebbles, limestone, granite, basalt, diabase, andesite, etc. It has the advantages of shaping function, cubic shape and high bulk density. It is essential for the production of machine-made sand equipment.
