Disclosed is a method for dislodging resin which has adhered electrostatically to a belt feeder in the proximity of a Banbury mixer throat. This is a problem particularly where dual resins are being transported to the Banbury mixer at a predetermined ratio, and where a preferential adherence of one resin may occur due to electrostatic charging differences, resulting in inaccurate formulation of the toner and difficulties in reclaiming the resin in a useful way. The improved method calls for the installation of a brush above the Banbury throat to contact the moving belt and thereby dislodge the adhered resin. The brush can be equipped with a flicker bar to remove resin that might adhere to the brush and can be cammed away from the belt when single resin feeding is employed, to avoid premature undesirable wear of the belt.
