What is Crushing?

Crushing is a mechanical size reduction process for large chunks of friable material such as rocks or ceramics. The crushing is achieved by using compressive forces between two plates  to break the substrates. One plate is typically fixed in a “V” alignment while the other plate reciprocates resulting in the crushing action. The gap between the plates can be adjusted to accommodate different incoming sizes and the desired crushed output. The pieces remain in the jaws until they are small enough to pass through the gap at the bottom of the plates. The size of the crusher is designated by the opening at the top of the plates (feed opening).

By using multiple passes through the crusher, material can be reduced to finer particle sizes using this process: crush the material, screen and discard fines, package good material, reduce the jaw gap and crush the overs again (repeating as many times as necessary).

Factors to Consider
  • What is the starting size of the material?
  • Is the material friable?
  • Does the material need to be screened after crushing?
  • Is metal contamination an issue?
  • Is a magnetic detection step required to remove potential contaminates?
