Impact Crusher


The impact crusher can be widely used in water, electricity, highway, artificial aggregate production, crushing business and so on. This series of impact crusher which is fit for hard rock crushing has special crushing structure, high chromium plate hammer, special impact plate.

Application of impact crusher

This series of impact crusher are optimized after adopting advanced techniques. It's widely applied in mining, energy, transportation , construction and chemical industry and mainly used to crush many kinds of large, medium, small hard size materials with compression resistance no more than 350Mpa,in the fields of highway, reservoir, railway, airport and other fields that need rock with cubic shape. It can crush granite, basalt, bluestone, etc the diameters of which are from 100mm to 500mm, and its crushing compression strength is not more than 320Mp. They are ideal choice for crushing and screening.

Features of impact crusher

1.Special structure, connected without key, high chrome hammer, unique impact liner, deal with hard material, high efficiency and save energy, cubic shape of product, adjustable output size.

2.The impact crusher is distinguished for unique structure, keyless connection, high-chromium plating hammer and special impact liner plate;

3.It is capable of highly efficient hard rock crushing while saving energy;

4.The product is in the shape of a cube, and the discharge grain size is adjustable to simplify the crushing circuit.

Structure of impact crusher

The materials are bumping with each other when being sent to the space between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking at the plate hammer. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.

The main advantages of impact crusher

1, Simple structure, small volume, light weight, large production capacity, so the production cost is low. Big feeding port ,high crushing cavity, adapt to the high hardness material;

2, Ore crushing along the joint surface, therefore, less power consumption, high efficiency;

3,Big crushing ratio, can reach 40, thus simplifying crushing process, can make the three sections of the broken into two segments or a broken, lower mill equipment costs;

4, Counterattack plate and plate hammer clearance can convenient adjustment, the effective control of the material particle size, particle shape well;

5, High chromium plate hammer, impact resistance, abrasion resistance, impact large;

6, Keyless connection, maintenance is convenient, economic and reliable;

7, Complete crushing function, high productivity, low abrasion, high comprehensive benefit;

8, It has selective crushing effect, and the broken product granularity evener, mostly were made cube shape stones. For bridge construction, construction of the high-speed road, port, airport has a wide range of applications.

Working principle of impact crusher

When the impact crusher works, the motor drives the rotor rotate with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers effect, 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 effects for being recrushed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won't stop untill the material are crushed to the required size and then discharged from outlet.
