What is the difference between a jaw crusher and a hammer crusher?

From the working principle, the jaw crusher belongs to extrusion crushing, and the working part is two jaws, one is the fixed jaw (fixed jaw), which is fixed vertically (or the upper end is slightly tilted to the outside) in the front wall of the machine body, and the other is the movable jaw (movable jaw), which is tilted in the position, and forms the crushing cavities (working cavities) with the fixed jaw in large and small sizes. The movable jaw plate carries out periodic reciprocating motion to the fixed jaw plate. When separating, the material enters the crushing chamber and the finished product is discharged from the lower part; when approaching, the material between the two jaw plates is squeezed, bent and split.

Hammer crusher belongs to impact crushing, mainly relying on impact energy to complete the operation of crushing materials. Hammer crusher work, motor-driven rotor rotates at high speed, the material enters into the crusher cavity evenly, the high-speed rotating hammer impact, shear tearing material crushing, at the same time, the gravity of the material itself makes the material from the high-speed rotating hammer rushed into the framework of the baffle plate, sieve bars, in the lower part of the rotor, there are sieve plate, the crushed material is smaller than the sieve size.

Scope of Application:

Jaw crusher is a kind of coarse crushing equipment, its main function is to initially crush large stones, widely used in the first crushing of crushing production line and sand making production line.

Hammer crusher belongs to medium and fine crushing equipment, widely used in secondary crushing.
