Definitions

  • the reference numeral 1 indicates a rotor of the defibrator and 2 a stator drum, which both are divided into three conical zones 3, 4, 5 and 6, 7, 8 respectively.
  • a screw feeder 9 rotating together with the rotor and located in a feeding channel 11 situated at the center of a housing 10.
  • the stator 2 is lbolted by the bolt 12 to the housing 10.
  • the housing in turn is through an intermediate ring attached to a frame 14 by means of bolts 15, thus forming adjacent the intermediate ring a stock discharge space 16 of the defibrator, from which space the stock is discharged in a known manner.
  • the base angle of the cones of the conical zones of the rotor and stator 3, 4, 5 and 6, 7, 8, respectively is greatest in zones 3 and 6 and decreases being smallest in zones 5 and 8.
  • the base portion of zones 3 and Wee 4 have cylindrical zones 17 and 18 which each terminate at walls 19 and 20 perpendicular with respect to zones 17 and 18 and defining the zones 4 and 5 respectively, opposite which walls 19 and 20 and at a distance from them cor-responding to the width of the zones 17 and 18 the stator 2 has corresponding parallel walls 21 and 22 and cylindrical zones 23 and 24 parallel to zones 17 and 18.
  • zones 18 and 17 need not necessarily be parallel to the rotor axis but can have a conicity similar to that of the zones 3 and 4 or even differing from the same.
  • Defibrator particularly for refining paper stock comprising rotatable rotor provided with bars and a stationary stator drum mounted around the same and preferably provided with bars, the rotor and stator both being divided into at least two zones having an increasing diameter in the feeding direction of the stock, characterized in that the zones are conically widening in the feeding direction and that the base angle of the cone decreases from zone to zone in the feeding direction of the stock.
