Abstract
A particle separator is provided that separates small particulate from large particulate from an intermixed material feed. The separator finds particular utility in the field of separation of thermoplastic regrind particulate from intermixed debris which constitutes a smaller particulate relative to the thermoplastic regrind. Embodiments of the separator use a rotary shaft for mounting an spiral blade fed by a material feeder bin that meters material into the separator. The spiral blade is configured so that the material moves along a peripheral mesh screen to separate any smaller particulate that passes through the mesh screen leaving the large particulate to traverse though the separator, while small particulate is sieved therefrom the surrounding mesh and into a separate collection stream. The spiral blade is mounted to a central magnetic axis to achieve removal of unwanted foreign spurious metal shavings or particulate that may be introduced to molding materials due to mechanical wear of the processing machinery.
