The impact crusher usually acted as the secondary crushing equipment in a complete crushing plant, after the jaw crusher. This kind of crusher is mostly used to crush the material of the fineness lower than 120-300 mm with a compression lower than 320Mpa. It has a wide application prospect in the fields like metallurgy, the construction, the infrastructure, the chemical industry and the phosphate industry. In addition, the impact crusher also has the advantages of higher contents of cubes, high efficiency, east maintenance and low cost, which the cone crusher hasn’t. So for the stone of low hardness and if you want a higher productivity, we recommend this impact crusher for you as the secondary crushing equipment.

It is a kind of crushing equipment, using impact energy to crush materials. When materials get into the area where the board hammer plays a part, under the impact function of board hammer at a high speed, the crushed ones are thrown to the impact device above the rotor continuously. And then they are rebounded from the impact liner to the area where the board hammer plays a part, and are impacted again. The materials from large ones to small ones get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to the required sizes and discharged from down of the machine.

The blow bar, the impact plate and the liner plate are all made of the highly hard and wear-resistant materials, which is small in size but light in weight. It may help to replace the spare parts. 
Most of the products are cubic in shape, and the discharging fineness can be adjusted on your own. 
The impact crusher is good for the hard and big stones; there is little contents of powder in finished products. 
It has a novel structure and can be working smoothly and stably. 
It is quite energy-efficiency, even with big output and a big crushing rate.
