Crushing equipment is essential in aggregate production line. Reasonable equipment configuration is related to the investment cost, production cost, product quality and product yield of the whole production line.
Cone crusher and impact crusher are both commonly used in secondary crushing process, so what is the difference between these two stone crushers and how to select? Here we will introduce 8 differences between impact crusher and cone crusher.
1. Different structures
The obvious difference between impact crusher and cone crusher is that the crushing principle and appearance structure are different, which are easy to distinguish.
2. Different working principles
The impact crusher adopts impact crushing principle, and the materials are repeatedly impacted and broken between the plate hammer and the impact plate.
The cone crusher adopts the combination of extrusion, shearing and grinding to crush the materials sandwiched between the moving cone and fixed cone.
3. Different scope of application
The hardness of materials crushed by impact crusher and cone crusher is different.
Cone crusher is mainly used to crush some materials with higher hardness, such as granite, basalt, tuff, river pebble, etc.
Impact crusher is often used to crush materials with small hardness and brittleness, such as limestone, limestone, etc.
4. Different discharge granularity
Generally speaking, the discharge granularity of cone crusher is finer than impact crusher.
In the actual production process, cone crusher is often used in the beneficiation process, while impact crusher is mainly used in building materials and construction engineering.
5. Different grain shapes of finished products
The impact crusher produces good grain shape, with less edge angle and more powder; the finished product of cone crusher has more needle and flake shape.
6. Different production capacity
Compared with impact crusher, cone crusher has the characteristics of low energy consumption, large output and stable production, so cone crusher is often used in large-scale production line with high output.
7. Different input costs
The price of cone crusher is more expensive than that of impact crusher, but its wear resistant parts have a longer service life, which avoids the trouble of frequently replacing parts. In the long run, cone crusher has higher cost performance than impact crusher.
The early purchase cost of impact crusher is lower, but the maintenance cost is higher; the cost of cone crusher is higher in the early stage and lower maintenance cost in the later stage.
8. Different degrees of environmental protection
The noise and dust pollution of impact crusher are larger compared with cone crusher.
In conclusion, the impact crusher and cone crusher both have their own advantages and disadvantages. In actual production, it is necessary to make a reasonable selection based on the comprehensive consideration of materials property, the feed and output materials size, and the production capacity requirements etc.
