Abstract
Granule cleaner and method comprises a hollow elutriation column into which dust- and debris-adulterated pellets are blasted on a high velocity air stream through an upwardly inclined injection tube to form a floating suspension in said column. Suction withdraws the lighter suspended material from the top while the heavier particles fall to the bottom. A.C. electrostatic dischargers diametrically disposed opposite conductive portions of the injection tube which may be ground-isolated (and also opposite ground-isolated conductive portions of the column below the injection level of the granules therein) to neutralize both the entering contaminated granules and the falling cleansed pellets, the conductive ground-isolated portions defining reference electrodes for balancing ion emission.
