Abstract

The invention relates to the refining of fibre material in devices having grinding surfaces which move relative to each other, with it being possible drastically to reduce the energy consumption by means of a combination of measures, with the measures principally consisting in the grinding procedure being carried out with a drastically reduced grinding frequency and with an increased dwell time of the fibre material between the grinding surfaces, by these latter being made cylindrical or conical, and, at the same time, with the principal part of the steam which is produced during the refining being removed from the grinding slit. The invention is consequently of great importance for lowering the costs when producing pulp, first and foremost high-grade mechanical pulps.
