摘要

The main driving force in thermomechanical pulp (TMP) refiner development has been towards higher production rate refining lines. High production in the refining line offers both low investment and production costs for a paper mill. High production in the TMP line also produces pulp at lower energy consumption [1]. This has become increasingly important considering continuously rising energy prices and "real-time" electricity pricing. Papier Masson was the first pulp and paper producer to build its new TMP line based on the single-refiner line concept in 2000. The refining line comprises two RGP-82 conical disc (CD) refiners followed by a low-consistency refining stage with three parallel refiners, screening and one RGP-82CD reject refiner. This line feeds one newsprint paper machine based solely on TMP pulp. Paper machine speed has been increasing continuously from its start-up and, accordingly, major efforts have been made to increase the TMP line production capacity. Production in 2000 was 640 BDMT/D. Recently, the production has exceeded 800 BDMT/D. Paper quality has not been compromised and pulp strength has been maintained at a high level. This paper presents results from mill-scale development work focusing on main-line high-consistency refiners. Main improvements have been seen as a result of steam-separation technology, refiner-control strategy, and refiner segment developments. A new refining efficiency formula [2], developed in Tampere University of Technology, for main line high consistency refining is also applied. This theory provides a new approach to analyzing the effects of refiner line operating conditions.
