-34- ABSTRACT OF THE DISCLOSURE Disclosed is a method and apparatus for avoiding the clumping of dry fibers having diameters and lengths in certain ranges during blending of such fibers into a dry or wet particulate material. The process comprises distributing fibers in a vaporous medium, and transporting fluidized fibers to a mixing zone containing a dry or wet particulate material. Concurrently with stirring and blending of the particulate material with fluidized fibers, the fluidized fibers having been separated at least partially from a fluidized vapor are gradually introduced into the mixing zone. This process avoids the phenomena of "balling" that otherwise occurs with certain fibers. 6274mus RI-6274MUS
