Abstract:Based on bar edge length, according to the refining mechanism of disc refiner, bar contact area was introduced into the study of refining intensity. Combined with the main bar parameters that affected refining quality such as bar width, groove width, bar angle, inner and outer diameter of refining plate, etc., the refining intensity theory of specific contact surface load (SCSL) was deduced according to the theoretical research on refining strength. The correctness of SCSL was verified through seven low-consistency beating experiments towards bleached softwood pulp on disc refiner with different bar width, groove width, bar edge length and speed. The conclusions not only improved the existing refining intensity theory to a certain extent, but also provided guidance for the selection of refining plate and design of bar of disc refiner. |
