Performance characteristics of impact crusher

(1)The crushing ratio of crusher is very large, the breaking ratio of general crusher is not more than 10, but the crushing ratio of counter crusher is 30-40. The maximum is 150.
(2) High crushing efficiency and low power consumption, because the impact strength of general materials is much lower than that of compressive strength, and because the material is subjected to the high speed action of the impact board and the impact of many times, The material breaks first along the interface and where the microstructure is weak, so this kind of crusher has high crushing efficiency and low power consumption.
(3)This crusher uses kinetic energy to crush the material, and the kinetic energy of each material is proportional to the mass of the material. The bulk material is broken to a large extent, but the material of the smaller city grain is not broken under certain conditions, so the size of the broken product is uniform and the phenomenon of over-crushing is less.
(4)In the process of impact crushing, the material is first broken along the cleavage surface in order to produce monomer separation.
(5)This crusher can crush brittle, fibrous and medium hard materials, especially for brittle materials.
(6)The equipment is small in volume, light in weight, simple in structure, easy in manufacture and convenient in maintenance.
Based on these obvious advantages of the counter-attack crusher, it is widely used and developed in various countries at present. However, the counter-attack crusher also has its disadvantages. When crushing hard materials, its plate hammer (hit plate) and counterattack plate wear faster. In addition, The impact crusher is a kind of machine which is rotated at high speed and broken by impact. The precision of parts processing is high and the service life can be prolonged only by static balance.
