Described lining tile periphery is provided with stopping means, described main casing is provided with the fixture matched with stopping means.
Described lining tile periphery is inclined-plane, installs the wedge-shaped bar matched with inclined-plane between inclined-plane and main casing.
Described extruding and kneading unit is made up of transport screw section and reverse acting spiral section.
Radial clearance between described dynamic roll flute disk side and the lining tile medial surface of its radially adjoining is identical.
Described sealing device is rubber weather strip or band.
Described fixture is bolt.
Compared with prior art, the beneficial effect that obtains of the utility model:
1. the utility model adopts the extruding and kneading unit be made up of transport screw section and reverse acting spiral section, crumples, seethes, good mixing effect.
2. in the utility model, cylinder mill can replace high-density paste mill, when not increasing too many power and equipment cost, effectively reduces bundle fiber content.
3. the adjustable roll flute gap of the utility model makes the adaptability of equipment more extensive, can be produced the slurry of different fiber situation and different deduction degree by control gap.
