Abstract

The invention relates to a method and a device for adjusting the whiteness degree of a bulk material consisting of comminuted paper fractions, especially deinking material, the bulk material containing fractions that mainly stem from newsprint paper, magazine paper and interfering substances. The aim of the invention is to improve the whiteness degree of such bulk materials. To this end, the bulk material is divided up into a light fraction and a heavy fraction by means of an air separator, the dust particles contained in the bulk material being at least partially removed as the light fraction. The invention further relates to an air separator with a housing (2) that is provided with a bulk material inlet (4), and a main separator stage (10) adapted to separate in a transverse direction. Said main separator stage has a guide surface (12) that supplies the bulk material to a chute edge (14) and an air entry duct (16). An auxiliary separator stage (22) is adapted to carry out a countercurrent separation. The cross-sectional area of the auxiliary separator stage (22) is larger by a factor of 1.1 to 1.8 than the cross-sectional area of the main separator stage (10).
