The working principles of the medium and fine impact crusher are completely same as the working principles of the coarse impact crusher. The basic structure is similar, but the parts some differences. The most obvious difference is the shape and the supporting method of the impact crusher. The cone of the coarse impact crusher is in heavy pitch. However, the cone of the medium and the fine impact crusher is the light pitch. In terms of the former kind of impact crusher, the moving cone is set forward and the fixed cone is set upside down, in which there are parallel bands with different degrees. For the latter kind of the impact crusher, the moving cone and the fixed cone are upright, and length of the parallel band is completely same.
According to the shape of the crushing cavity, the medium and fine impact crusher can be divided into the standard type, the intermediate type and the short-head type. Let’s take the standard impact crusher as an example to introduce the working principles of the impact crusher.Henan Hongxing coal crusher will be your best choice.

The main components of the impact crusher are composed by the rack, external cone, the inner cone and other parts. The transmission of this kind of machine starts from the motor and it is supported on the transmission shaft in the bronze bushing through the eccentric shaft, transmission chain and the flexible coupling. Then it rotates around the center line through the gear. There is bronze bushing in the rack. The inner bar of the eccentric shaft bushing is manufactured in to the eccentric cone hole. The bottom of the inner cone is in spherical shape, which is supported on the concave spherical watts of the rack. The lower cone part of the spindle inserts in the bush. The centerline of the spindle and the centerline of the crusher form the 205 angle. When the eccentric sleeve rotates, the outer surface of the inner lining sometimes closes the outer cone and sometimes leaves the outer cone so that the materials can be uniformly crushed.
