摘要

A device for refining and equalizing fibrous materials suspended in a liquid, for the manufacture of paper, cardboard or similar products, consisting of a hollow body, in the longitudinal walls of which extend parallel to each other, are arranged on both sides of a provided chamber in the central part of the hollow body, grinding rotors equipped with tool sets and operated in opposite directions, characterized in that this chamber is divided in the area of the upper side of the inlet tube by means of an intermediate ceiling in an entrance chamber, of which is supplied by the suspension by elongated openings to the rotors, and in a separation and classification chamber of fibers, in which the rotors make penetrate, or pass, under pressure the product to be ground, in countercurrent, from the circulation radial of matter, taking each time partial quantities, and in a dome chamber with an evacuation tube, in which it ascends and is dislodged the portion of useful material, while the portion of matter retained slides on the intermediate ceiling back to the radial circulation of matter.
