The PULVERISETTE 6 is a planetary ball mill with one grinding station and an internal unbalance compensation. Because of the high ball acceleration a significantly higher comminution rate is achieved compared with centrifugal ball mills. The comminution in closed vessels guarantees loss-free milling (including suspensions).

Apr 13, 1993 The total weight of the ball mill when fully charged is about 280 t. The ball mill is driven through a girth gear at a speed of 16 rev min~1 and is mounted on the head wall of the ball mill. The girth gear, 6360.6 mm in diameter, is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor.

Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times.
