  • Multiple Core Spiral Separator and Method Therefor
    Publication number: 20130341255
    Abstract: A spiral separator apparatus is used to separate a mixture of particles of different shapes. The spiral separator apparatus includes rotating separator cores that each have a number of banked flights. As the separator cores rotate, non-round particles continue traveling down the banked flights, while round or substantially round particles are ejected from the separator core by centrifugal force. Particles that are ejected from the separator cores impact a housing, fall, and are collected, for example, in a collection bin.
    Type: Application
