ERIEZ - DensitySort® Magnets

Eriez’ economical DensitySort® quickly sorts nonferrous fines into two fractions; Twitch(light fraction) and Zebra(heavy fraction) improving their value. Nonferrous fines from automobile shredders typically contain 8-12% red metals. By further separating these metals processors can increase their fines' value by more than 20%! The DensitySort separates metals of different specific gravities using air, vibration, and slope. Material is fed at the low point of the table's slope. Its own specific mass directs the particles into low density or high density collection bin.

Gravity aided by the unit's air and vibration action enables over 70% red metal recovery and production of a clean aluminum (Twitch) fraction. The middlings are collected and recycled into the process.
