| Abstract:Logarithmic spiral was applied to the design of disc refiner plate and conical refiner rotor based on its features. The teeth on the surface of refiner plate in the radial show logarithmic spiral shape, so that the refiner teeth intersecting angle of the rotor and stator remained constant during the refining process. The refiner with such plate could increase fiber collapse and effectively retained fiber length under the same conditions, and improved the refining quality. |
