[origin: US2001015389A1] Process and device for dispersing a fibrous paper web which comprises a substantially consistent fibrous paper material. The device includes an inlet for fibrous paper material, a stationary stator, and at least one rotatable rotor. The stator and the at least one rotor form a pulverizing zone including a pulverizing element located near the inlet for the fibrous paper material, the pulverizing element including least one of scrapers and knives for pulverizing the fibrous material into a fine, friable material; a vapor chamber forming a ring about the pulverizing zone, the vapor chamber being for calefying the fine, friable material formed by the pulverizing element; and a dispersing zone including at least one row of teeth on the stator and at least one row of teeth on the at least one rotor which can be moved relative to the at least one row of teeth of the stator.
