Hammer crusher is the use of high-speed impact hammer effect on the material for crushing operations in the broken and broken machinery. Hammer hinged on high-speed rotation of the rotor, the lower part of the grate body to control the marker size. Materials into the crusher by the first high-speed movement of the hammer and the impact of the initial break, and also gain kinetic energy, high-speed fly on the wall case has again been broken plates and broken. Grate the material is less than the gap is discharged outside the machine, the material is greater than the gap grate grate on the block again in the impact and grinding by the hammer, until the gap is less than the grate after discharge.
Hammer crusher is with crushing ratio, uniform particle size nesting, too little crushed material, lower energy consumption. However, due to rapid wear hammer, broken in the application of the hard material has been limited,addition, as the grate of the fear of congestion,do not use it with crushing humidity and clay materials. This crusher is usually used for crushing limestone, shale, coal, gypsum, chalk, etc materials.
