An agitator shaft (22) is diposed in a milling body (12) which includes a grinding chamber (18) to be filled at least partly with grinding media (50) and material (52) to be ground and has an inlet for material to be ground and an outlet for crushed material. The agitator shaft (22) has an end portion (38) in which a cavity (40) is formed which is open at the inner shaft end. The end portion (38) comprises recesses (46) all around the cavity (40) to permit grinding media (50) to flow off which entered the cavity (40) through the inner shaft end. A separating means (42) is arranged inside the cavity (40) to permit finished pulverized material (52) to flow out of the grinding chamber (18) to the outlet (30) while it retains grinding media (50). In this manner the separating means (42) is effectively protected from any direct impact of activated grinding media (50). And yet the risk is avoided that the separating means (42) becomes clogged, by virtue of the rotation of the agitator shaft (22).
