Abstract (en)
[origin: EP1158088A2] Treatment of a fiber suspension, especially for paper and/or cardboard production, to load the wetted fiber surface with additive(s), especially filler, is carried out (partly) in a fluffer, in which the fibrous material of the suspension is split to increase its specific surface area and optimize its accessibility for educts. An Independent claim is also included for the plant including fluffer used in this process.
