The selection function gives the probability that a single particle will be broken, when several particles are compressed.

  • Cone Crusher an overview ScienceDirect Topics

    Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.
