Comparison and Analysis of Common Jaw Crusher Types

Impact Crusher

Impact crusher use scope: It can handle all kinds of 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, and artificial gravel, crushing and other industries.
Impact crusher performance characteristics: Unique structure, no key connection, high chromium plate hammer, a unique counterattack liner; hard rock crushing, high efficiency and energy saving; product shape is a cube, adjustable size of the discharge size, simplify the crushing process.
Impact crusher working principle: During work, driven by the motor, the rotor rotates at high speed. After the material enters, it collides with the plate hammer on the rotor and then it is broken. Then it is counterattacked to the liner and broken again, and finally discharged from the discharge port.
The most used in the production of a concentrator or a gravel plant is a jaw crusher. Compared with other crushers, this machine has the advantages of low cost and high efficiency.
Jaw crusher

Jaw crusher wear requirements are very high, the general choice of materials for high wear-resistance manganese steel liner. When the machine is working, it has two jaw plates inside the crushing chamber (manganese steel), and a jaw plate is fixed and is called (fixed jaw). It is slightly inclined from the upper end to the outer edge and fixed in the crusher cavity. On the front wall of the body, another common name for the seesaw is our tongue-in-the-wall motion. It is also called the tongue. The position is inclined, and it forms a trapezoidal crushing chamber (work chamber) with a fixed jaw plate.
The movable jaws are reciprocated against the fixed jaws and crushed and rubbed, then separated and then approached. When the two seesaws are separated, the material immediately enters the crushing chamber. At this time, the already finished product is discharged from the bottom of the crusher; when the two sampan plates come together, the material entering the crushing chamber is subject to two defects. The pressing force of the plate’s extrusion belt kneads the material, thereby bending and crushing the material and breaking the material. The entire process of breaking the material is achieved.
