Impact crusher, also called impact breaker, from China-Hongxing Machinery, has applications in the limestone, coal, salt, and gypsum mining. It is used to crush boulders into fine aggregates where the compressive strength of the materials is less than 150Mpa. The crusher series also includes a mobile system.
The system has a powerful motor that drives the hammer at high speed. The material is hit by the hammer as it enters the crushing zone and is thrown on a impact plate, only to rebound back on the hammer and be thrown on the next impact plate in the series. This hammering breaks down the material into fine aggregates, which escape the system once they are reduced down to a certain size. The impact crusher from China-Hongxing machinery has specially designed tooth impact plate for breaking rocks to desired size. It also has an adjustable discharge opening to select the size of aggregates that can exit the crusher. The system has wide reduction ratio where the feed material size can be as large as 1.3-1.5 m, while the discharge size is as low as 3-150 mm.
