Use cone crusher or impact crusher in secondary crushing stage

In the production of engineering sand and gravel aggregate, crusher is an important equipment. The reasonable arrangement of the equipment directly affects the investment cost, production cost, product quality and yield rate of the whole production process.

Among the secondary crushing equipment, cone crusher and impact crusher are two common ones. What is the difference between these two types of equipment and how to choose?

A. Working Principle

Impact crusher utilizes the theory of impact crushing, so that the material is crushed by repeated collisions between hammers and rebound plates.

Cone crusher utilizes a combination of squeezing, shearing and grinding, where the grinding wall keeps moving towards the grinding wall, squeezing the material sandwiched between the grinding wall and the grinding wall into powder.

B.Scope of Application

Impact crusher and cone crusher can be used as secondary crushing device, only the hardness of the crushed material is different.

Impact crusher is mainly used to crush hard materials such as granite, basalt, tuff, pebbles and so on.

Cone crusher is suitable for crushing materials with less hardness and easy to break, such as limestone, limestone and so on.

C. Discharge size

Cone crusher is more delicate in granularity.

D. Discharge particle size

Impact crusher has good quality particles, and the crushed products have less edge and more powder; the crushed products of cone crusher are mostly needle-like and flake-like particles.

E. Difference in processing capacity

Cone crushing equipment has the advantages of low energy consumption, large output, stable performance, etc. Therefore, cone crusher is widely used in large-scale, high-yield production line.
