摘要
In the apparatus to disperse a high consistency fiber material, a rotor (1) and a stator (2) toothed structure are in a rotary symmetrical shape and coaxial to each other with concentric rows of teeth (3,3',4,4') forming channels between them. The shortest radial stretch (a) of the channels, formed between the radially outer or outermost teeth (4') of the stator teeth (2), is at least twice the shortest radial stretch (b) of the channels of the radially inner neighboring teeth (4') of the stator tooth structure (2). Preferably the shortest radial stretch (a) of the radially outer channel (7) can be at least three times the length of the shortest radial stretch (b) at the radially inner neighboring teeth (4') of the stator tooth structure (2). The shortest radial stretches (a,b) correspond to the radial extension of the tooth points. The shortest radial stretch of the outermost row of teeth is at least 5 mm. The flank angle of the teeth working with the flanks of counter teeth is 10-45 degrees against the axial lines, and preferably 15-30 degrees . The axial height of the outermost teeth (4) of the stator tooth structure (2) extends over the height of the remaining teeth (4,4') of this tooth structure. The tooth structures have a ring-shaped heating zone, fed with hot steam, radially within the rows of teeth to disperse the material.
