Abstract:
A method for applying a liquid coating to a flowing bulk material feed stream, comprising:conditioning an incoming bulk material feed stream to produce a substantially ribbon-like aggregation flow pattern; introducing said conditioned bulk material feed stream traveling in a first direction into a first spray section having a first concave wall surface which reverses a flow direction to a second direction opposite said first direction; applying, in said first spray section, a liquid coating to an exposed surface of said bulk material feed stream; directing said bulk material feed stream from said first spray section into a second spray section having a second concave wall surface being concave in a direction opposite that of said first concave wall section, reversing, on said second wall surface, said flow direction to said first direction, applying, in said second spray section, a liquid coating to an exposed surface of said bulk material feed stream.
