Hammer crusher is to use high-speed impact hammer effect on the materials and fine pieces of broken machinery operations. Articulated high-speed rotating hammer rotor, the body has a lower grate section to control the size marker. Materials into the crusher by the first high-speed movement and the initial impact of hammer crusher, and kinetic energy at the same time, high-speed toward the wall on the chassis of the broken plates and broken again. Article grate gap is less than the materials from the plane, the gap be greater than the grate in the grate be expected to block the hammer once again under the impact and grinding, until the gap was smaller than the grate be discharged.

Hammer crusher with broken than large, uniform particle size nesting, have been less crushing materials, low energy consumption. However, due to rapid wear hammer, broken in the hard materials has been limited application; another grate be afraid as a result of congestion, it should not be broken in the humidity and the material containing clay. This crusher is usually used to broken limestone, shale, coal, gypsum, chalk, etc. the following hard-brittle materials.

Will hammer crusher hammer steel ring for the ring for the coal machine, hammer crusher is the variant. It uses high-speed impact and the combination of low-speed rolling to broken materials, thus eligible for the finer products are mainly used for crushing coal for power plants, but can also be used for gypsum, salt, chemical raw materials and some materials in the broken hardware.
