Method of controlling wood pulp production in a chip refiner
A method of controlling quality of wood pulp produced in a chip refiner comprises refining wood chips in a refining zone of a chip refiner with formation of a mass of pulp fibre, determining a fibre filling factor of the fibre in the refining zone from the actual mass of fibres in the refining zone...

| Zusammenfassung: | A method of controlling quality of wood pulp produced in a chip refiner comprises refining wood chips in a refining zone of a chip refiner with formation of a mass of pulp fibre, determining a fibre filling factor of the fibre in the refining zone from the actual mass of fibres in the refining zone and the mass of fibres in the refining zone when the refining zone is full, and adjusting as necessary, at least one operating parameter of the chip refiner selected from reduction of production rate, increase in production rate and reduction of energy input, in response to the filling factor determined, to achieve a desired pulp quality. |
