The difference between jaw crusher and impact crusher in crusher

The scope of application of the impact crusher: it can handle various coarse, medium and fine materials (granite, limestone, concrete, etc.) with a side length of no more than 500mm and a compressive strength of no more than 350mpa. It is widely used in hydropower, highways , Artificial sand and gravel, crushing and other industries. The performance characteristics of the impact crusher: unique structure, keyless connection, high chrome hammer, unique impact liner; hard rock crushing, high efficiency and energy saving; the product shape is cubic, and the discharge size is adjustable, simplifying the crushing process.

The working principle of the impact crusher: When working, the rotor rotates at a high speed under the drive of the motor. After the material enters, it collides with the plate hammer on the rotor and is crushed, and then it is impacted on the liner again and crushed again, and finally discharged from the discharge port . The jaw crusher is the most commonly used in the production of concentrators or sandstone plants. Compared with other crushers, this machine has the advantages of low cost and high efficiency.

Jaw Crusher Jaw crushers have very high requirements for wear resistance. Generally, the material used is high wear-resistant manganese steel liner. When the machine is working, there are two jaw plates (manganese steel) inside the crushing cavity. One jaw plate is fixed, also called (fixed jaw), which is slightly inclined outward from the upper end) and is fixed in the crusher cavity. On the front wall of the body, another jaw plate that moves back and forth is commonly called (moving jaw), which is also called jaw tongue. The position is inclined, and it forms a trapezoidal crushing cavity (working cavity) with the fixed jaw plate. The movable jaw plate carries out the reciprocating movement of crushing belt rubbing against the fixed jaw plate, then separates and then approaches. When the two jaws are separated, the material immediately enters the crushing cavity. At this time, the crushed products are discharged from the bottom of the crusher; when the two jaws are brought together, the material entering the crushing cavity is subjected to two jaws. The squeezing band of the plate has the force of kneading, thereby bending and splitting the material to break the material. Carry out the whole process of material crushing.
