Hammer crusher and impact crusher are two common crushing equipment in the aggregate and mineral processing industries. Both of them can be used to crush hard materials, but there are some differences between them.
The Chinese hammer crusher is a type of hammer crusher that is widely used in the mineral processing industry. It is suitable for crushing hard and brittle materials, such as limestone, coal, and so on. The hammer crusher uses the impact force generated by the high-speed rotation of the hammer to crush the material, so it is mainly used for crushing operations with low hardness and low abrasiveness. The main disadvantage of the hammer crusher is that it is easy to wear and tear, so its service life is relatively short.
The impact crusher, on the other hand, uses the impact force to crush the material. The material is first fed into the crusher and then hit by the high-speed rotating hammer. The impact force generated by the hammer crushing the material can be adjusted by changing the rotor speed and the gap between the hammer and the impact plate. The impact crusher has a higher crushing ratio than the hammer crusher and is more suitable for crushing hard and abrasive materials. The impact crusher also has a longer service life than the hammer crusher and is more energy-efficient.
In conclusion, both the Chinese hammer crusher and the impact crusher have their own advantages and disadvantages, and the choice between them should depend on the specific requirements of the production process. If the material to be crushed is of low hardness and low abrasiveness, the hammer crusher may be a better choice. If the material is hard and abrasive, the impact crusher may be the better choice.
