  • Single-disc refiner
    Patent number: 10441954
    Abstract: A single-disc refiner (1) has a stationary refining element (2) and an opposed rotatable refining element (12), each of which has a radially inner blade element (4, 14) providing an inner refining surface area and a radially outer blade element providing an outer refining surface area. The inner and outer refining surface areas of each refining element together provide a refining surface of the refining element, the refining surfaces defining a feed zone (29) followed by a treatment zone (30) with a transition point therebetween located at a radial distance of 70-90% from the center of the refiner or at a radial distance of 50-80% from the innermost edge (25, 27) of the refining element or at a radial distance of 20-50% from the inner edge (34) of the outer blade element (8, 18, 33) towards the outermost edge (26, 28, 35) of the refining element.
