The Refiner disc plate are critical to the operation of the refiner. Each size disc has a different tooth mark type, which treats the fibers in the pulp by moderately cutting, loosening, and separating. Fibers in beating will absorb water and swell and give high elasticity and plasticity, so as to meet the production requirements of paper machines to ensure the quality of paper.
Double Disc Refiner is composed of two fixed grinding discs fixed on the main body of the mill shell and on the stator feed knife disc and two rotor grinding discs installed on the rotor positioning disc to form two grinding zones. The slurry enters the centre of the grinding zone from the two slurry feeding tubes on the shell body and the stator feed disc, passes through the grinding zone under the action of centrifugal force and slurry feeding pressure, and completes the pulping process through the pressing and crushing impacts of the tooth discs in the grinding zone, and then is sent out by the slurry outlet. The rotor positioning disc and the main shaft adopt spline floating coupling, which can make flexible axial movement. It adopts elastic cylindrical pin coupling for smooth running.
