FRACTIONATING AND REFINING SYSTEM FOR ENGINEERING FIBERS TO IMPROVE PAPER PRODUCTION

A system for treating cellulosic fibers to improve paper， board and tissue quality; the system involves splitting fibers into an original portion having original fibers and a refinable portion. The refinable portion may further be fractionated by one or more fibers properties by a fiber fractionation system into a first fraction and a second fraction. The refinable portion as a whole， or a fractionated fraction thereof， is then refined to produce refined fibers. Varying amounts of the original unrefined fibers， refined fibers and possibly additionally fractionated unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized paper product. A master control system， fiber measurement system and optional fractionation maintenance system may be integrated with the overall system to regulate all processing.

一种用于处理纤维素纤维以提升纸张、纸板及薄页纸品质的系统。该系统将纤维分离为含有原生纤维的原生纤维组分与可精炼纤维组分。可精炼纤维组分可通过纤维分级系统，依据一项或多项纤维性能参数进一步分级为第一分级组分与第二分级组分。可精炼纤维组分整体，或其某一分级组分，随后将被精炼以获得精炼纤维。将不同配比的原生未精炼纤维、精炼纤维，以及可选的额外经分级处理的未精炼纤维进行混合，制备得到优化浆料；该浆料经造纸机加工后可制得优化纸张产品。可将主控系统、纤维检测系统及可选的分级维护系统集成至整体系统中，以调控全流程加工工序。
