Impact crusher and cone crusher, although belong to the second crushing equipment, are placed in the coarse crushing machine. It can be used to finish secondary fine crushing of various sand and aggregate materials. However, there are obvious differences when observed carefully. Taking pebble as an example, which machine is more suitable for crushing pebbles?

Differences

Impact crusher: The material is crushed by collision and friction between the hammer and impact plate. In addition to the crushing function, it also has a certain effect of micro-shaping. The material particles treated by it are of uniform size, with low content of needle-flake and reasonable gradation. The size of finished product is good, and the needle flake is less.

Cone crusher: It has been improved on the basis of the traditional cone crusher, and crushes materials by adopting the lamination crushing principle. Its crushing effect is still slightly weaker than impact crusher. Although the grain shape is not very good, it is widely used in the current market due to its low energy consumption, large output and stable production.

Different stone raw materials have different hardness characteristics, so impact crushers and cone crushers also feature different performances in stone crushing.

Impact crusher is suitable for crushing soft rock, such as limestone, dolomite, weathered rock, etc. Cone crusher is more suitable for crushing stone raw materials of high hardness, such as river pebbles, granite, quartz stone, basalt, etc.

Pebbles are not as soft as limestone and shale. It is recommended to choose high wear resistance equipment when selecting processing equipment, such as cone crusher. Although the treatment effect of the cone crusher is not as good as that of impact crusher, it has a strong processing capacity. It does not cause excessive wear when crushing high-hardness materials such as pebbles. With high output, it can create higher economic benefits for investors. Therefore, the cone crusher is a better choice for pebble crushing.
