Impact Crusher

Impact Crusher

Impact Crusher is optimized after adopting advanced techniques,and the capability of impact crusher got advanced very much!Impact Crusher is mainly used to crush many kinds of large, medium, small materials whose side length is less than 500mm, and compression resistance should not be more than 350Mpa. The impact crusher is widely used in building material, hydroelectricity,artificial stone and sand, highway, etc.

Working Principle of Impact Crusher:

When the impact crusher works, the motor drives the rotor rotate of the impact crusher 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 till the material are crushed to the required size and then discharged from outlet of the impact crusher.


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.

Repair and maintenance of Impact Cursher

Impact crusher is a crushing equipment with high-speed rotation and inertia. It is very important to do well normal handling and maintenance for safe operation in the long run.
Before starting, impact crusher needs to inspect the equipment carefully, for example,fasteners is loose or not,the tear and wear should be replaced or not,lubrication and cooling system is ok or not,etc.
impact crusher should start as following sequence: dust removal equipment--conveying equipment—crusher and feeder. These machines shoud run withour load firstly,after making sure there is no abnormal condition,these machines can run with load.
When stopping machines running, impact crusher should be according to the sequence of production flow chart, which is in contrary to the starting sequence: Feeder has to be stopper firstly,when materials in crusher is discharged completely, then main motor and final product conveying equipment system can be stopped.
Materials should be feeded continuously and evenly to prevent bigger material than required size and metel from being feeded.
In the process of running, you should pay more attention to inspect lubricating system, adding or replacing the lubricating oil regularly. The temperature of rotor-bearing should be below 60 °, the max temperature can not exceed 70 °;
When the final product size is too big,we should stop to check the wear pattern of hammer and impact plate, the clearance between hammer and impact plante,sealing and dust collection in workshop should be done well.
