ABSTRACT:
A method of regulating sorting systems, in particular multi-stage sorting systems, in paper production and a sorting system working in accordance with the method are described, in which the fiber suspension supplied in each case to a sorting stage is separated into at least one fine fraction and one coarse fraction and at least one portion of a coarse fraction is sorted again and at least the fine fraction thereby obtained is returned to the sorting process, with the mass flows at the input side and the output side being detected at each sorting stage of the sorting system by online measurement and/or by calculation and the values obtained being supplied to a processor associated with the sorting system for mathematical modeling and state regulation of the sorting system and with the mass flows at the output side and/or selectable machine parameters of the sorting system being influenced in dependence on pre-settable target parameters such as production, efficiency, fiber loss and the like.
