<p>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.</p> |
