ABSTRACT:
A blower beater mill in which a rotor has a beater portion provided with beater arms in the form of two interconnected parts. Beater arm bases are fastened in hub rings of the shaft of the rotor, and fastening elements of two beater arm portions are located above shaft crests of the hub rings. Cover elements are located axially with the rotor in a free space between the beater arm bases, and these cover elements are located on a diameter between the shaft crests of the hub rings and the fastening elements of the beater arm portions. Openings pass through the beater arm bases between the cover elements and the shaft crests of the hub rings in the axial direction of the rotor. An opening in one beater arm base is aligned with the opening in the corresponding beater arm base of the following beater arm rows. The cover elements have an outside jacket which surrounds the shaft crests of the hub rings at a distance. The jacket has cutouts for accommodating the beater arm bases. The cover elements, furthermore, are connected to the beater arm bases, and they are tip-stretched as lateral connecting pieces to the beater arm bases. The narrower side walls of the centered beater arm bases face the side walls of adjacent beater arm bases of the same beater arm row, at a slight distance.
