With more than 20 years experience, Zhengzhou Great Wall Heavy Industry Machinery Co., Ltd. has been a top and porfessional manufacturer of various crushers, stone crusher, impact crusher, jaw crusher, cone crusher, hammer crusher, vibrating screens, feeders and conveyors.

I. Usage and Application
This impact machine is used for primary, secondary, fine crushing mining and rocks (for example, the granite, marble, and limestone) materials no more than 500mm in length and compressive strength less than 350 MPa. It is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on.

II. Advantages
1. Special construction, non-key connected
2. High chrome broad hammer, unique impact scaleboard
3. High efficiency and low power consumption
4. Cubi shaped end products
5. The granularity of the end products can be changed, and the production line is simple

III. Working Principle
The materials are crushed via impact energy produced in the crusher. When the materials enter the zone of the board hammer, they are flung into the impact equipments via the high-speed impact of the board hammer. These materials will be re-crushed after rebounding into the scale board. The large materials are crushed into small pieces until it reached the specified granulites. The end products come out from the base of the machine.
