Two new solutions from Conair, Cranberry Township, Pa., are designed for use with its TrueBlend line of blenders to allow feeding thin, flaky regrind without repelletizing. For small quantities, TrueBlend blenders can be fitted with side feeders with steeply angled sides that help prevent the regrind from hanging up and bridging. Material then can flow easily through an oversized opening at the bottom to a horizontal auger that feeds the mixing chamber.

For larger quantities of scrap, such as are typically consumed in pipe extrusion, blenders can be equipped with lift augers to eliminate bridging and promote free flow (photo). The lift augers are positioned at an angle in a corner of the regrind bin; instead of forcing material out of the bin as most conventional augers do, they turn in the opposite direction, moving regrind up and away from the bottom of the bin. This keeps material loose so that it can flow through oversized side gates into the mixing chamber.
