LOW SPEED LOW INTENSITY CHIP REFINING

摘要

In the mechanical refining of wood chips to produce wood pulp, wood pulp quality is improved by employing low refining intensity at least in a final refining stage; the refining is carried out in a double disc refiner or a single disc refiner at rotational speeds that are lower than those conventionally employed, specifically at less than 1200 RPM in a double disc refiner and at less than 1500 RPM in a single disc refiner.
