Abstract
A disc refiner wherein the operating faces of its discs are arranged to have interdigited teeth disposed in radially spaced rows and to further have dams interposed between selected successively adjacent of said rows. The dams are characterized by being parallel to said rows and substantially coextensive therewith. Each dam is accordingly substantially continuous and each serves in the operation of the discs to block substantially all material moving across the face of the disc of which it forms a part and causes it to be deflected outwardly and to impact on the operating face of the opposing disc. The arrangement is such to insure that as the material the constituents of which are to be separated moves across the respective operating faces of opposed refiner discs it will be repeatedly thrown from one disc operating face to the other and in the process have imposed thereon a forceful separation of constituent parts.
