With the application of new type highabrasive materials, Zhengzhou Dehong Machine Manufacturing Co., Ltd produced impact crusher at the first time to break traditional limitation.

Although the improved type is still in the process, the type in application is only used to crush middle hardness materials.

Under the hammering action, materials are crushed firstly from the most fragile level. This kind of crushing will get high ratio of cubic-shape materials. Then the needle flake percentage could be lower than 10% instead of higher than 15% by Jaw crusher, cone crusher and roller crusher in the production.
Hence it could limited the application of impact crushers.

With the changing standard about aggregates in the infrastructure, the ratio of impact crusher in use becomes much higher with more perfection function.

Here is a deep analysis about impact crusher.

During the five common kinds of crushers, impact crushers and hammer crushers both belong to the machines to crush brittle materials.

Advantages of impact crushers could be fine shape production and crushing ratio more than 50 which Jaw crushers, cone crushers and roller crushers less than20.
For the working principle of impact crushers is the impact of strike parts such as hammer, baffle, strike back board and so on which are high abrasive.

All the mentioned advantages take most important part in crushers.

When the tube mill is used in cement production line, the single hammer crushers could be the best choice especially in the productivity more than 20000t/d cement production line.
Meanwhile the best plan is to use the big type coarse crusher for the requirement of output size.
