Abstract (en)
[origin: EP0423091A2] A refiner for the refining of paper pulps or the like, comprising oppositely placed refiner blades (2, 3), at least one of which rotates, an intake (11) for the pulp to be refined and an outlet (12) for the refined pulp. A drawback with conventional refiners is that the pulp fed into the refiner is not refined uniformly because there is no provision for selecting the pulp fractions to be refined. The invention solves this problem in that one or more of the refiner blades (2, 3) are provided with one or more top separators (6) which are at least partially conical and fixedly connected to the blades.
