20130299397, Nov 14, 2013

Filed:

May 10, 2012

Appl. No.:

13/468877

Inventors:

Steve Eugene DeJong - Maple Grove MN, US
Dennis DeJong - Maple Grove MN, US
Chad Culbertson - Zimmerman MN, US

International Classification:

B07B 13/00

US Classification:

209606

Abstract:

A spiral separator apparatus is used to separate a mixture of particles of different shapes. The spiral separator apparatus includes a rotating separator core that has a number of banked flights. As the separator core rotates, 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 core impact a housing, fall, and are collected, for example, in a collection bin.
