Apparatus and method for manufacturing fibre mass suspension

摘要

A fiber mass suspension is produced by mixing together a fiber material (FM) and water (W) in a pulper (1). The formed fiber mass suspension is divided into an accept fraction and a reject fraction. The reject fraction is supplied continuously to a first secondary pulper (2) for further screening and defibring. The accept fraction formed in the first secondary pulper (2) is supplied continuously for further processing and the reject fraction formed in the first secondary pulper (2) is supplied continuously to a second secondary pulper (3) for further processing. The accept fraction formed in the second secondary pulper (3) is supplied continuously for further processing.
