Dear Eduardo,

In the crushing of stone, it is generally required to combine primary crushing and secondary crushing to complete crushing production. The primary crushing is usually use jaw crusher, and the secondary crushing usually use cone crusher or impact crusher. Then, in the secondary crushing, is it better to use cone crusher or impact crusher? Firstly, let's look at the difference between them:

1. Different applications

Cone crusher and impact crusher are all fine crushing equipment, but the hardness of the materials used for them are different. In general, cone crusher is suitable for crushing granite, basalt, river pebbles, iron ore, gold ore and other high-hardness rocks and metal ores, while impact crusher is suitable for crushing medium and low hardness materials such as bluestone and limestone.

2. Different crushing principle and appearance structure

Impact crusher uses the impact energy to crush the material. The material is repeatedly impacted and crushed between the hammer and the impact plate. The cone crusher adopts the laminating crushing principle. The rolling motar wall continuously moves toward the broken wall, and squeeze the material between them. Therefore, if it is a high-hardness material, the wear of the impact crusher is greater.

3. Different capacity

Compared with impact crusher, cone crusher has the advantages of low energy consumption, large capacity, stable production, etc. So it is often used for large-scale and capacity line operations.

4. Different discharge size

Cone crusher has a variety of crushing chamber types such as coarse, medium, fine and superfine, and its discharge granularity is finer than that of impact crusher. In actual production, there are more cone crushers in the field of beneficiation, and more impact crushers are used in building materials and construction projects.

5. Different finished grain shape

The shape of the impact crusher particles is good, the edges of the finished products are less, the powder is more, and the cone crusher has low powder.

6. Different costs

The cone crusher price is higher than impact crusher, but the wearing parts have a long service life. Impact crusher has higher maintenance cost.

In summary, there are advantages and disadvantages in impact crusher and cone crusher. Which equipment should be used depends on actual production conditions, such as material hardness, capacity and capital. You can submit the production requirements to our online customer service. We will arrange professional technicians to customize the complete line configuration for you.
