Abstract
The present invention constitutes a mixing and feeding apparatus for use in association with solid chemicals such as fiberglass and certain plastics. The mixing function is achieved by a circumferential tumbler, having a plurality of longitudinal prongs, which rotates in a first direction. Concurrently with the rotation of the tumbler, an axial flight screw, axially disposed within the tumbler, rotates in an opposite direction. The rotation of the flight screw interacts with the tumbler to perform a mixing function while also serving to advance the solid material from the mixer to a discharge area.
