Abstract

The invention relates to a method for the production of cellulose particles by means of dispersing a cellulose solution in a precipitant, in addition to a device for carrying out said method. The method is characterised in that the cellulose solution is dispersed by the shear load produced with the aid of a refiner in the precipitant, and the cellulose is regenerated or precipated in a dispersed form. The device is characterised in that it contains a disk refiner, which has axial boreholes in the stator disk and plate for the introduction of the preciptant. According to the invention, it is possible to produce fibrous cellulose particles having a defined average fibre length with excellent homogeneity fibre material.
