Both the impact crusher and the cone crusher are medium and fine crushing equipment in the sand and gravel aggregate production line. They are usually used after the coarse crushing of the jaw crusher to further crush the coarsely crushed stones, and then screen them to produce 5-10, 10-15, 15-20, 20-31.5mm stones of different specifications.

At the same time, in terms of working principle and practical application, impact crusher and cone crusher are two different crushing equipment.

1. In terms of working principle, the impact crusher adopts the principle of impact crushing. The stone is crushed by repeated impact between the blow bar and the impact plate, and the wear rate of the vulnerable parts is high. The cone crusher adopts the principle of laminated crushing, which can use the crushing effect between the stones to reduce the impact and wear on the machine

2. In terms of practical application, it is precisely because of their different principles that they are different in application. Impact crushers are usually used in soft rock crushing, such as limestone, weathered stone, construction waste, etc. The cone crusher is usually used in hard rock crushing and metal ore crushing, such as granite, basalt, river pebbles, iron ore, copper ore, etc.

3. In terms of finished product shape and output size, the finished stone of impact crusher have better particle shape, more cubes, and less needle flakes, while cone crusher has higher crushing efficiency and higher output. This is the general consensus of everyone. What’s more, with the continuous improvement and innovation of crusher technology, the new type of impact crusher has also broken through the bottleneck of production capacity, and it is no longer a problem for the hourly output to reach hundreds of tons or even thousands of tons. The laminated crushing principle of the cone crusher also greatly improves the particle shape and quality of the finished stones, and can produce high-grade high-speed railway and road construction materials.

4. In terms of cost input, the early purchase investment of impact crusher is less than that of cone crusher, but if it is used for hard rock crushing, it will wear more vulnerable parts, and frequent replacement of parts is required in the later stage, resulting in higher maintenance costs. In the long run, the post-maintenance production cost of the cone crusher is lower than that of the impact crusher.

Therefore, the issue of whose cost is lower, the impact crusher or the cone crusher, cannot be directly discussed. The appropriate machine should be selected according to the production requirements such as materials and output. Only the appropriate machine can fully exert its production function and avoid Unnecessary loss, thereby reducing overall costs.
