When the jaw crusher is working, the movable jaws make periodic reciprocating motions to the fixed jaws, sometimes approaching and sometimes leaving. When approaching, the material is crushed, split, and impacted between the jaws; when it is removed, the broken material is discharged from the discharge opening by gravity.

In the process of breaking large stones into small stones, the first crusher is usually a “main” crusher. The longest and most solid crusher is a jaw crusher. When feeding the jaw crusher, the material is poured from the top inlet into the crushing chamber containing the rake teeth, and the rake teeth force the material against the wall of the chamber and break it into smaller stones. An eccentric shaft is supported for the movement of the caries, and the eccentric shaft penetrates the frame of the fuselage. Eccentric motion is usually generated by flywheels fixed at both ends of the shaft. Flywheels and eccentrically supported bearings often use spherical roller bearings, which must withstand large shock loads, abrasive sewage, and high temperatures

The advantages of jaw crusher:

1. The crushing force is large, which can crush very hard materials. The vibratory jaw crusher has greater crushing capacity than the conventional crusher. The crushed materials include titanium iron alloy, artificial crystal, silicon calcium alloy, ferrochrome, ferromanganese and the like.

2. The crushing ratio is high and the work efficiency is fast. The jaw crusher is 2-3 times higher than the crusher of the general crusher, and the crushing efficiency is faster.

3, the structure is novel, there will be no blockage. The vibratory jaw crusher adopts a high dynamic impact velocity. By using the principle of inertial transmission, when the material cannot be broken, the mineral will be discharged from the discharge port with the movement of the crusher.

4, can start, stop, overload work under load. The jaw crusher directly drives the eccentric weight by the motor and is not affected by the material in the crushing chamber.

5, the force is fast, with impact characteristics. The vibratory jaw crusher exerts a great degree of steepness on the material, and the force is fast and pulsating.

6. The size of the discharge opening can be adjusted in advance according to the output and other requirements. The grit crusher production particle size requirements depend on the thickness of the material layer and are not affected by the size of the discharge opening.
