What kind of crusher should be selected for secondary crushing?

As a secondary crushing machine, the striking difference between the impact crusher and the cone crusher is that the crushing principle and appearance of the structure is different, which is easy to distinguish.

The impact crusher adopts the principle of impact crushing, and the material is repeatedly smashed between the hammer and the impact plate.

The cone crusher adopts extrusion, shearing, grinding combined crushing, rolling mortar wall constantly moving to the crushing wall, squeezing the material between the two to make it crushed.

In addition, there are also many differences between the impact crusher and the cone crusher in actual production.

1. Difference scope of application

Both the impact crusher and the cone crusher can be used as secondary crushing machine, but the hardness of their crushing materials is different.

Generally speaking, the cone crusher mainly crushes some hard materials, such as granite, basalt, tuff, river pebbles and so on.

The impact crusher is used to break less hard materials, such as limestone and so on.

In short, the impact crusher is suitable for crushing the hardness and below the small degree of toughness, brittle materials, while the cone crusher is suitable for crushing hard materials.

2. Discharge granularity is different

The particle size of the impact crusher and the cone crusher are different.

Generally speaking, the cone crusher can crush more thin materials than that of the impact crusher.

In the actual production, the cone crusher is used more often in mineral processing technology, and the impact crusher is used more often in building materials and construction engineering.

3. The final granule type is different

The impact crusher has good grain shape, less edges and corners and more powder.

In the finished products of the cone crusher, the needle-shaped granule is more, and the granule is not as good as that of the impact crusher.

4. Different capacity

Compared with the impact crusher, the cone crusher has the characteristics of low energy consumption, large capacity and stable production, so the cone crusher is often used in large-scale production lines with high capacity.

5. Input costs vary

The price of the cone crusher is more expensive than the impact crusher, but its fragile pars have a long life, which can avoid the trouble of frequently changing parts. In the long run, the cone crusher is more cost-effective than the impact crusher.

The impact crusher has low purchase cost in the early stage and high maintenance cost in the later stage.

The cone crusher has high cost in the early stage and low input cost in the later stage.

6. Different levels of pollution

The impact crusher has more noise and dust pollution while the cone crusher has less pollution.

In addition, the cone crusher has higher performance for counterattack, high capacity, less effort for crushing harder materials, and longer service life of wear parts.

In the long run, the cone crusher is more cost effective than the impact crusher.

To sum up, the impact crusher and the cone crusher have advantages and disadvantages. in the actual production, to choose which kind of machine, the end users need to consider the different materials, the materials particle size, the capacity and other aspects.
