ABSTRACT:
Apparatus and method for applying liquid coating to pellets in a flowing feed stream are provided. An incoming bulk material feed is conditioned to produce a ribbon-like agglomerated flow pattern, and the bulk material is passed through a first spray section which coats an exposed surface of the pellets flowing therethrough. The flow direction is reversed in a second spray station, which operates to expose an opposite surface of the pellets, such that the second spray section coats substantially the remainder of the outer surface of the pellets.
