ABSTRACT:
Apparatus for controlling the refining of fibrous lignocellulosic pulp in a drum refiner in which the pulp stock, or grist, is conveyed into a cylindrical stationary drum and propelled therein in a linear direction in a pulsating fashion by a co-axial rotor comprising a plurality of wings which attack the grist in a wedging action as it is pushed ahead of the leading faces of the wings and which induce in the grist internal frictional shear forces while it is forced through a gap defined between the leading edges of the wings and a series of shear means arranged axially along the interior surface of the stationary drum. The process is controlled by coordinating the angle of attack on the grist by the wings and corresponding variations in the gap clearance with the energy demands or mechanical power input.
