ABSTRACT:
An apparatus and process for making pellets from a fluidizable material having a fluid bed chamber with a perforated base and an open upper end in which a rotatable means for shaping the pellets is located. Gas for the formation of a fluidized current is introduced through the perforated base. A fluid spray for the agglomeration and coating of the fluidizable material is introduced into the fluid bed chamber, preferably near the perforated base in the central area of the fluid bed chamber. Additionally, a device for channeling agglomerated material is preferably located at a distance above the perforated base and concentrically with the longitudinal axis of the sprayer. A fluidized current carries particles, while still plastic, upwardly through the channeling device causing them to impinge on the underside of the rotatable means. The rotatable means thereby shapes the agglomerated material, and urges the shaped material outwardly where it falls toward the perforated base and is recirculated to form larger pellets. The apparatus and process also includes other treatments of the material such as coating and drying, as the material is pelletized.
