Title: Friction based material sorter

Abstract

A method and apparatus are provided for separating elastomeric materials from mixed material streams. A separator includes a bank of parallel rollers extending longitudinally between a first end and a second end. The bank of parallel rollers having a predefined inclination with the first end elevated higher than the second end. Mixed material streams are fed onto a top surface of the high end of the inclined parallel rollers. A material having less friction and elasticity slides down the inclined roller bank top surface are collected into a collection bin positioned adjacent the second, lower end of the roller bank. Other materials having a higher friction coefficient grip the rollers more and are lifted out of the valley due to friction migrating perpendicular to the rotating rollers and are collected in a collection bin positioned adjacent one side of the roller bank parallel to the longitudinal roller axis.
