In the construction of sand and gravel aggregates, the use of crushers accelerates the development of construction. The reasonable accessories of equipment in the production line match the production cost of the entire production line, product quality and effective use of equipment. During the use of the equipment, the coarse crushing equipment generally uses a jaw crusher. The jaw crusher has a large processing capacity and is aimed at various soft and hard materials. In terms of secondary crushing, there are two options. Different equipment is selected according to the nature of the material, among which the impact crusher and the cone crusher are secondary crushing equipment, so how to choose the secondary crusher correctly under what conditions?
 

Different scope of application
Both impact crusher and cone crusher can be used as secondary crushing equipment, but the hardness of the crushed materials is different.
The cone crusher mainly crushes some materials with high hardness, such as granite, basalt, tuff, river pebbles, etc.
The impact crusher is used to crush materials with low hardness and brittleness, such as limestone, limestone, etc.


Discharge particle size is different
The particle size of the crushed materials of the two types of crushers is different. Generally speaking, cone crushers crush finer materials than impact crushers.
In the actual production process, cone crushers are used more in beneficiation process, while impact crushers are used more in building materials and construction projects.


Different grain types
The impact crusher has good grain shape, less edges and corners of the finished product, and more powder. There are many needle-shaped particles in the finished product of the cone crusher.


Different throughput
Compared with the impact crusher, the cone crusher has the characteristics of low energy consumption, large output and stable production, so the cone crusher is often used in large-scale high-output production line operations.


Different input costs
The price of cone crusher is more expensive than that of impact crusher, but its wearing parts have a longer life, which avoids the trouble of frequent replacement of parts. In the long run, cone crusher is more cost-effective than impact crusher.
The purchase cost of impact crusher is low in the early stage, and the maintenance cost in the later stage is relatively high; the initial cost of cone crusher is high, and the investment cost in the later stage is low.


Different degrees of environmental protection
The noise and dust of the impact crusher are relatively large, and the cone crusher is relatively small and has a higher degree of environmental protection.
In summary, the impact crusher and the cone crusher have their own advantages and disadvantages. In actual production, it is necessary to comprehensively consider the properties of the materials, the particle size of the incoming and outgoing materials, and the output to make a reasonable selection.
