Optimizing Low Consistency Refining
October 20, 2013
Refining this type of pulp is generally performed at high consistency for the preservation of length. Advances in fabrication methods have allowed the development of low intensity plates that are capable of refining the pulp to the same quality targets as high consistency refining but at lower energy consumption. This was shown in the trials. From the three different intensity levels tested (0.15 J/m, 0.45 J/m & 0.65 J/m) it was shown that low intensity refining was capable to develop pulp properties matching those of HC refined pulp. Results from trials show that an energy saving of 50% is possible. A report of this work is under review and will be made available to all partners in the coming months.
