Refiner, for beating cellulose fiber suspensions to give papermaking pulp, is a double-disk type with adaptor disks at the stator and/or rotor to carry beating disks of different types

摘要

The refiner (1), to process a cellulose fiber suspension, has a housing (2) with a stator (5) keyed to the housing inner wall, and a rotor disk (6). At least part of the beating disks (7-10) are fitted to the stator by screw bolts or the rotor by an adaptor disk (18,19). The working disk is held on at least one side of the rotor disk in the radial direction by a clamping ring (15).
