Development of Impact Crusher


Brief Introduction of Impact Crusher

Impact crusher is widely applied in mining, transportation, energy, construction and chemical industry.

There are two types of impact crushers:horizontal shaft impactor and vertical shaft impactor.

Impact crushers involves the use of impact rather than pressure to crush material.When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine.

Impact crusher features reasonable structure,excellent performance,high crushing efficiency,easy operation and maintenance. The most outstanding advantage of the impact crusher is that its finished powder is in good, cubic shape and without tensility and cranny.   

Of course,Impact crusher cannot be aero shotcoming. For instance,impact crusher could only crush middle-hard materials.

Development in China

China had Impact Crusher in the late fifties. Before the eighties domestic impact  crusher are limited to deal with mid-hard material such as coal and limestone. Until the late eighties, Shanghai construction company introduced KHD-type hard rock impact crusher to fill this gap. However, a lag of 20 years compared with foreigh conuntries.

At the beginning, the important parts such as board hammer of domestic Impact crusher depend on import. Chinese government pay more attention to the development of this field and domestic board hammer became ministerial-level scientific research project in the "Eighth Five-Year" period. With a big success, domestic hammer not only replaced the import products, but also exported to Europe, Japan and other countries. Wear-resistant parts provided great effort to development of impact crusher.
