Abstract

A separator is disclosed for mechanically separating objects having one size dimension less that a predetermined threshold size. The present separator comprises a cylindrically- or barrel-shaped device having one or more louvers. The barrel is oriented at a preset angle and rotated about its longitudinal axis (along its circumference) and powered by a motorized drive. A collection of objects (processed materials or heavy metal particles from shredder operation) are introduced into the higher opening in the barrel. As the collection of objects progresses downward through the barrel, a plurality of machined slots or louvers separates the larger objects from the smaller. The present invention separates the collection of objects into two separate paths, comprising two products, which are 1) an overflow path, comprised essentially of objects that exceed the maximum allowable size through the louvers and fall through the lower end of the device; and 2) an underflow path, comprised essentially of objects that are able to pass through the louvers. The objects in the underflow path are collected separately from those in the overflow path.
