The invention relates to an internal centrifugation device for fine mineral fibers having a diameter that is less than or equal to 3 µm. The inventive device comprises a centrifuge (1) provided with a peripheral strip that is pierced by orifices. The height of the fibering (H3) pertaining to the centrifuge (1) is less than or equal to 35 mm, especially less or equal to 32.5 mm and preferably between 16 and 32.5 mm. The orifices (14) of the centrifuge (1) are grouped together in rows, whereby at least two adjacent rows have different orifice diameters.
