After the jaw crusher impact crusher comes in handy which can carry the material to second crushing , so as to achieve the desired particle size. However,for some hard materials, there are two problems, first is the fast replacement frequency of wearing parts and followed by is the high dust content in crushed materials. So how to solve the two problems about producing the hard materials ?we briefly introduce it to you.
Hope the conclusion comes from repeated tests by our technical personnel make help for you:

Firstly,for the first question:high frequency of replacing wearing parts, you can use higher wear resistance accessories such as high manganese steel to solve for high manganese steel has the character of brittle and hard, hard and tough which reducing the frequency of replacement.

Secondly, for the material after crushing having high dust content, there are several methods to solve this problem:
1 put some small amount of water onto the materials before crushing for there are little dust when crusher acting on wet materials;
2 make screening on the materials before they are crushed;
3 impact crusher is sealed in the crushing work hours, seal the place of dust-producing with sealing device will reduce dust and pollution to the environment;
4 equipped the impact crusher with dust removal device to eliminate dust.
