ABSTRACT:
A paper manufacturing conical-type pulp refiner comprising a support structure 1 for a framework 2 with a front lid 3, and defining a refining internal and conical chamber 4, with a single and axial exit 5 and a radial side exit 6. The refiner further including a refining set including a rotatory axis 7, with the end centered inside the refining chamber 4, where the refining set itself is mounted, composed by a stationary conical pair and by a rotatory conical pairs, the latter interlayed between those, forming two refining conical surfaces. The rotatory conical pair being formed by a conical rotor 8 with the smaller base endowed with openings 9, involving an internal cylindrical cube 10 fixable on the rotatory axis 7 free end, receiving on its internal and external faces, the respective internal 11 and external 12 refining conical, thereon steadily disposed, composing a rayed conical rotor; and on their turn, the internal 13 and external 14 refining conical composing the stationary conical pair fixedly mounted respectively on the framework 2 refining chamber 4 bottom and on its front lid 3 internal face, directed respectively towards the rayed conical rotor internal 11 and external 12 refining conical, and with the consequent delimitation, among them, of two intermediate conical surfaces or refining zones.
