As a type of stone crusher , the impact crusher has its unique working principle. And its unique working principle overcomes the many defects of hammer kind crushing equipment. While hammer crusher has much power, the discharging particles maybe mainly granular. In order to reduce the jam phenomenon, the impact crushing machine can effectively deal with those materials.

Impact crusher can be used to crush both of the soft material and the very large hardness material. When the rotor moves, the plate hammer which is fixed to the rotor and designed to adopt the mechanical firm structure can get more force from the rotator. Compared with the hammer crusher, the rotor of impact crusher is more suitable to crush the more hard material and saving energy.

The size of the discharging particle's adjusting range of the impact crusher is large, and it can be adjusted very simply. There are several ways to adjust the discharging particle of impact crusher, such as adjust rotor speed, impact plate and the space of grinding cavity and so on. We can adjust the size of the gap through mechanical or hydraulic way. Compared with the hammer crusher, the impact crusher have fewer wear-resistant parts and higher use ratio of metal.

The cost of maintenance of the impact crusher is low since the replacement of spare parts is very simple. There are six plates hammers those were installed on the rotor. If we need to replace a set of plate hammer, it will only costs our few minutes. On the contrary, the hammer crusher has more than 100 pair of hammers, so it will really need lots of time to replace a set of hammer. At the same time, the hammer crusher costs higher when it needs inspection and maintenance .
