Impact crusher and cone crusher are both 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 stone and then screen it to produce 5-10/ 10-15/15-20/20-31.5mm stones of different specifications.

At the same time, in terms of working principles and practical applications, impact crushers and cone crushers are two different crushing equipment.

1. In terms of working principle, the impact crusher adopts the principle of impact crushing. The stone is repeatedly hit and broken between the plate hammer and the impact plate. The wear rate of wearing parts is high. The cone crusher adopts the laminated crushing principle, which can use the crushing effect between stones to reduce impact and wear on the machine.

 

2. In terms of practical application, it is precisely because of their different principles that they have differences in application. Impact crushers are usually used for crushing soft rocks, such as limestone, weathered stone, construction waste, etc. Cone crushers are 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 particle shape and output size, the particle shape of the stone produced by impact crusher is better, with more cubes and less needle flakes, while the cone crusher has higher crushing efficiency and larger output. This has been a common consensus. Know. The laminated crushing principle of the cone crusher also greatly improves the particle shape and quality of the finished stone, and can produce high-grade high-speed railway and highway construction materials.

 

4. In terms of cost investment, the initial purchase investment of an impact crusher is less than that of a cone crusher. However, if it is used for hard rock crushing, it will cause greater wear and tear on the wearing parts. In the later period, parts need to be replaced frequently, and the maintenance cost is high. In the long run, the later maintenance and production costs of cone crushers are lower than those of impact crushers.

 

Therefore, the question of which cost is lower, impact crusher or cone crusher, cannot be directly discussed. The appropriate machine must be selected according to production requirements such as materials and output. Only the appropriate machine can fully exert its production functions and avoid unnecessary losses, thereby reducing overall costs.
