The invention relates to an agitator ball mill (1) having a cylindrical grinding container (2). At least one inlet for material to be ground is formed at a first end region of the grinding container (2) and at least one ground-material outlet is formed at an opposite end region of the grinding container. A separating device (12) is arranged upstream of the ground-material outlet. An agitating shaft (3) connected to a drive via a drive shaft (4) is arranged within the grinding container (2). On an outer lateral surface of the agitating shaft (3) there are formed pins (6) as agitating elements (5) which transmit the drive energy of the agitating shaft (3) at least partially to grinding bodies (MK) arranged loosely within the grinding container (2). The agitating shaft (3) is designed to be at least partially hollow cylindrical. An end of the agitating shaft opposite to the drive is at least partially open. An inner shaft (10) is formed in the hollow cylindrical interior (9) of the agitating shaft (3), wherein a first end of the inner shaft is fastened, within the hollow cylindrical interior (9) of the agitating shaft (3), coaxially to the drive shaft (4) and/or coaxially to the agitating shaft (3) and wherein the opposite second end of the inner shaft (10) projects out of the hollow cylindrical interior (9) of the agitating shaft (3). The separating device (12) is arranged on the projecting, second end (11) of the inner shaft (10). The invention further relates to a method for operating an agitator ball mill. |
