Impact Hammer Crusher

Impact hammer crushers are of a progressive design that combines the advantages of impact crushers with those of hammer crushers. Crushers are predominantly used for single-stage crushing of extracted limestone, dolomite, gypsum, limestone marl as well as other medium hard materials and materials that contain sticking clays and loams. Generally, these crushers are used in the cement industry where ball mills are part of the grinding plant.



The rotor of crushers is fitted with staggered hammers that cover the entire working width of the crusher. This design together with the structural arrangement of the crushing chamber provides a high crushing ratio and has the capacity to process materials that could not be processed in the past. The grate is the second essential component of the crushing space and limits the use of the crusher with regard to the material stickiness. The grate is designed so that the functional plates act as a safety device when non-crushable matter is trapped into the crushing chamber. The plate pieces do not come into contact with the rotating hammers, instead, they fall freely into the discharging hopper positioned under the crusher.


Advantages:

  • High operating reliability

  • Low cost for operating and maintenance

  • Long service life of main crushing elements

  • High specifi c throughput

  • Excellent degree of comminution

  • Favorable specific electric power consumption

  • Favorable grain size distribution of the product

  • Capability to crush even materials containing sticky components

  • Insensitivity towards non-crushable matters
