NEW INSIGHT INTO REFINING

TROIS-RIVIERES, QC — A paper in the September 2000 edition of Appita Journal by Ken Law, Pulp and Paper Research Centre, Universit du Qubec Trois-Rivires, offers A new insight into chip refining. The paper examines some mechanistic aspects of chip refining and the characteristics of chip pressing. Perpendicular-to-grain compression has been emphasized as a possible strategy in mechanical conditioning of chips. Results from TMP pilot trials indicate that static compression is more beneficial in terms of energy savings and pulp quality when compared with conventional screw pressing.
