How To Choose A Secondary crusher? Impact Crusher Or Cone Crusher?

Same as secondary crushing equipment, the obvious difference between impact crusher and cone crusher is that the crushing principle and appearance structure are different, which is easy to distinguish. The impact crusher adopts the principle of impact crushing. The material is repeatedly impacted and crushed between the plate hammer and the impact plate.The cone crusher uses a combination of extrusion, crush material with shear and grind, and the concave continuously moves to the crushing wall, squeeze the material sandwiched between the two to crush it. In addition, there are many differences between the two in actual production.

1. Different scope of application

Both impact crusher and cone crusher can be used as secondary crusher, but the difference is two crushers for crushing the different hardness of the materials. Generally speaking, the cone crusher mainly for hard materials crushing, such as granite, basalt, tuff, river stone, etc., while the impact crusher is used for materials with low hardness, such as limestone. In short, the impact crusher is suitable for crushing materials with low toughness and brittle hardness and below, and the cone crusher is suitable for crushing hard materials.

2. Different discharge size

It is different for the material discharge size of the two kinds of crusher. Generally speaking, a cone crusher for finer materials than an impact crusher. In the actual production process, cone crushers are used more in the beneficiation process, while impact crushers are used more in building materials and construction projects.

3. Different types of finished products

The impact crusher has a good grain shape, fewer edges and corners of the finished product, and more powder. The finished product of the cone crusher has a not-good grain shape with many needle and flake grain shapes.

4. Different capacity

Compared with impact crushers, cone crushers is low energy consumption, large capacity, and stable production. Therefore, cone crushers are often used in large-scale and high-capacity production lines.

5. Different cost of investment

The price of the cone crusher is more expensive than the impact crusher, but its long life wearing parts avoiding the trouble of frequent replacement of parts. From a long-term perspective, the cone crusher is more cost-effective than the impact crusher. The low initial purchase cost of the impact crusher with the higher later maintenance cost, while the high early-stage cost of the cone crusher with the lower later investment cost.

6. Different degree of pollution

The impact crusher has high noise and dust pollution, and the cone crusher has less pollution.

In addition, cone crusher has higher performance than impact crusher, higher capacity, and less effort to crush harder materials with a longer service life of wearing parts. From a long-term perspective, a cone crusher is more cost-effective than an impact crusher. It can be understood that the low initial purchase cost of the impact crusher with the higher later maintenance cost, meanwhile the initial high cost of the cone crusher with the lower later investment cost.

In summary, the impact crusher and cone crusher have their own advantages and disadvantages. Which equipment to choose in actual production also needs to be comprehensively considered according to different materials, input and final sizes, and capacity.
