Description
Impact crusher is mainly used for breaking crisp material
under impact force. Compared with jaw crusher, cone crusher and
roller crusher, impact crusher has these features as follows:
A．It has big breaking ratio over *0, while that of the
crushers mentioned above is difficult to exceed *0.
B．It can obtain good final grain size. Under impact force, the
material usually is broken along the weakest layer, so it can
obtain cubic grain size with high probability and needle grain size
less than *0% compared with over *5% of other crushers. With cubic
grain size, impact crusher is used as final crusher for processing
concrete bone material in the road-building.
With good features mentioned above, impact crusher plays an
important role among other crushers. But it also has drawbacks, for
example, the wear parts such as plate hammer, impact plate are
subject to abrasion.
In order to overcome above drawbacks, the newly designed
crusher by our company has perfected structure of rotor and
improved clamping method of plate hammer which is made of by
high-wear material suitable for breaking hard rock. As per the
purpose of usage, such impact crusher has three types namely I, II
and III. Type I is suitable for breaking material with medium
hardness, and type II and III are used for hard-rock with
anti-pressure strength up to **0MPa such as basalt and andesite
which shall be crushed to grading stone material less than *9.6mm.
At present, such crusher has been used in many road construction
projects.
