Most aggregate producers are well acquainted with the selection of crushing equipment, and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. When choosing secondary crushing, both impact crusher and cone crusher can be used as secondary crushing equipment, so how to correctly choose secondary crusher under what conditions? Let's take a look at this issue below:

1. 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.

Cone crusher mainly used for crushing 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, coal gangue etc.

2. Different discharge particle size

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.

3. Different grain shapes of finished products

The impact crusher has good particle shape, the finished product has less edges and corners, and more powder; the finished product of the cone crusher has more needle-shaped particles.

4. Different processing capacity

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.

5. 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 high;

6. Different degrees of environmental protection

The noise and dust of the impact crusher are relatively large, and cone crusher is relatively small and has a higher degree of environmental protection.

In summary, the impact crusher and 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.
