Analysis of Advantages and Disadvantages of Cone Crusher and Impact Crusher in Secondary Crushing Stage

1. Different Application Ranges
   Both impact crushers and cone crushers can act as secondary crushing equipment, but they handle materials of different hardness levels. Generally, cone crushers are mainly used to crush harder materials, such as granite, basalt, tuff, and river pebbles, while impact crushers are used for softer materials like limestone and lime rock.
   In short, impact crushers are suitable for crushing medium-hardness or lower, less tough, and relatively brittle materials, whereas cone crushers are suitable for crushing hard materials.

2. Different Output Particle Sizes
   The particle size of the crushed material differs between the two types of crushers. Generally, materials crushed by a cone crusher are finer than those crushed by an impact crusher. In actual production, cone crushers are more commonly used in mineral processing, while impact crushers are more frequently used in building materials and construction engineering.

3. Different Finished Product Shapes
   Impact crushers produce a better particle shape, with fewer edges and corners in the finished product but more fines/powder. Cone crushers produce more needle-like and flaky particles in the finished product, resulting in a poorer particle shape.

4. Different Processing Capacities
   Compared to impact crushers, cone crushers have characteristics such as lower energy consumption, higher output, and more stable production. Therefore, cone crushers are often used in large-scale, high-production line operations.

5. Different Investment Costs
   The price of a cone crusher is higher than that of an impact crusher. However, its wear parts have a longer service life, avoiding the trouble of frequent part replacements. From a long-term perspective, cone crushers offer higher cost-effectiveness compared to impact crushers.
   It can be understood as: impact crushers have lower initial purchase costs but higher later maintenance costs; cone crushers have higher initial costs but lower later investment costs.

6. Different Pollution Levels
   Impact crushers have significant noise and dust pollution. Cone crushers have less pollution.

Summary
In conclusion, impact crushers and cone crushers each have their own advantages and disadvantages. The choice of equipment in actual production should be based on factors such as the material characteristics, required input and output particle sizes, and production capacity. It is recommended here that for small-scale aggregate production lines, using an impact crusher is sufficient. For large-scale aggregate production lines with hard materials, choosing a cone crusher is better. If there are very strict requirements on particle shape, a shaping machine can be added.
