Jaw Crusher VS Impact Crusher


Smashing is generally used for a section of crushing, which is to break a large material into equipment suitable for secondary crushing such as cone crusher, impact crusher, etc. If the feed is large, it must be broken as the first section. Broken, impact-breaking is generally not suitable for breaking marble, granite, and too hard materials, which will greatly reduce the wearing parts.


The jaw crusher is mainly used for medium-sized crushing of various ores and bulk materials, and can crush materials with compressive strength of not more than 320Mpa, which are divided into coarse and fine broken. The series of products are complete in specifications, and the feeding size is 125mm ~ 750mm, which is the first choice for primary crushing.

The finished product of the impact crusher is cubic, no tension and crack, and the grain shape is quite good. It can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with a feed particle size not exceeding 500mm and compressive strength not exceeding 50MPa. The size of the discharge material can be adjusted, and the crushing specifications are diversified.

Working Principle

When the jaw crusher is working, the motor drives the belt and the pulley, and the eccentric shaft moves the movable jaw up and down. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw. The material is crushed or chopped to achieve the purpose of crushing; when the moving down, the angle between the bracket and the moving jaw becomes smaller, and the moving jaw is separated from the fixed jaw by the action of the rod and the spring, and the material is broken at this time. Discharge from the lower opening of the crushing chamber. As the motor rotates continuously, the crushing maneuvering cycle motion crushes and excretes the material to achieve mass production.

When the impact crusher is broken, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of ​​the hammer, it collides with the hammer on the rotor, and then is thrown to the impact crusher device to break again, and then from the impact-liner. The upper part returns to the hammer action area and is re-crushed. This process is repeated, and the material is repeatedly broken into the first, second and third, impact crusher chambers until the material is crushed to the required particle size and discharged from the discharge port.
