Impact Crusher

General intro of Impact crusher

Impact crusher is suitable for materials whose compressive strength is under 350Mpa, and particle size is less than 500mm. With end products in cubic shape, the impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on.

PF Impact crusher

Adopting the latest manufacturing technology and unique structure design, the PF series impact crusher can produce cubic products with very good grain shape without tension and crack. It can crush each kind of coarse, medium and fine cubic material (granite, limestone and concrete) with feeding size not more than 500mm and crushing strength not more than 350MPa and is widely applied to secondary and tertiary crushing of various ores and medium-hard materials in railway, highway, energy, cement, chemical industry construction, etc.

Working principle of Impact crusher

When the impact crushing machine works, the motor drives the rotor which is installed with hammers at high speed. When the materials get into the area which the hammers affect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers function for re-crushing. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet of the impact stone crusher and mineral impact crusher.
1. The impact crusher is with unique simple structure, keyless connection.

Impact crusher is a new type of high-efficiency crushing equipment, which is characterized by small size, simple structure, large crushing ratio, low energy consumption, large capacity and uniform particle size. In addition, it also has the effect of selective crushing. It is a promising device. But its biggest drawback is that the plate hammer and counterattack board are vulnerable to the wear and tear, especially when it is used for the crushing of the hard ores, the wear and tear is more serious, which requires frequent replacement. Due to the emergence of some wear-resistant materials, they have been applied in some metal concentrators.
Impact crusher can be divided into single-rotor impact crusher, double rotors impact crusher and single-stage impact crusher and so on. Impact crusher can handle a variety of materials and rocks  (granite, limestone, concrete, etc.) whose particle size is not more than 120-500 mm and the compressive strength is not more than 320 Mpa. The impact crusher is widely used in water and electricity, highway, artificial aggregate sectors and other industries. The series of impact crusher is equipped with unique structure, high chrome hammer and unique counterattack lining. It is featured with the following characteristics:
1. It is suitable for the crushing of hard rock; high efficiency and energy saving;
2. The particle size is adjustable, which can simplify the crushing process;
3. It has large crushing ratio and high crushing efficiency.
Impact crusher is a kind of crushing equipment that makes use of the impact energy to break materials. When the materials enter the plate hammer area, they will be in the high-speed impact of the board hammer to make the materials constantly be thrown to the counterattack device, and then the materials will rebound to the plate hammer area from the counterattack lining to be crushed. The materials will stand the repeated crushing until the materials are crushed to the required size and discharged from the bottom of the machine.
