STRIRRING BALL MILL WITH A SHAFT FEEDTHROUGH

The invention relates to a shaft feed-through (2) of a drive shaft (7) of an agitator (6) of an agitating ball mill (1). The agitating ball mill (1) comprises a cylindrical grinding container (3), which is closed on both sides by end walls (4, 5). In the area of one of the end walls, the drive shaft (7) of the agitator (6) is enclosed by a shaft seal sleeve (21) and is guided through a central opening (10) in the end wall (5). The shaft feed-through (2) comprises a sealing module (27) enclosing the drive shaft (7) and the shaft seal sleeve (21) in the area of the central opening (10), which sealing module comprises at least one sealing element (35, 36, 37, 38) for sealing the central opening (10) of the end wall (5) with respect to the drive shaft (7), and a connecting unit (25), to which the at least one sealing element (35, 36, 37, 38) is assigned. The sealing module (27) is anchored to the end wall (5) by way of the connecting unit (25), wherein the anchoring is configured so as to be flexible, and comprises a flexible fastening element (30) between end wall (5) and connecting unit (25).
