The invention relates to a dual centrifuge (10) which has the following: a driveshaft (16), a rotor (20), which is mounted on the driveshaft (16) and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (30); an opening (18) in the rotor (20), wherein an end region (16a) of the driveshaft (16) at least engages into said opening; and an additional drive mechanism (32) for the rotational unit or the rotational units (30). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor (20, 40, 50) can be arranged on the driveshaft (16) at all times. The various rotor types (40, 50) are also adapted to the additional drive mechanism (32) for the rotational units (30) such that the function is not adversely affected. The invention is characterized by a design for operating at least one angular head rotor (40) and a swing-out rotor (50). For this purpose, the driveshaft (16) and the various rotor types (40, 50) are adapted to each other. The bearing (16), the driveshaft (16), and the various rotor types (40, 50) are adapted to one another such that each non-dual rotor (40, 50) has a geometry that is measured such that when the rotor (40, 50) is mounted, a drive means (32a) of the additional drive mechanism (32) for the rotational units (30) is arranged so as to not contact the mounted rotor (40, 50).

The invention relates to a rotor (10) of a dual centrifuge which can be rotated about a drive axis (A) in a centrifuge, which rotor comprises at least two rotary units (26) that are arranged symmetrically to one another and have a bearing (32) and a rotary head (30) which is connected to the bearing (32) and which is mounted in the bearing (32) so as to be rotatable about a rotational axis (R1, R2), which rotary head (30) can be driven about the rotational axis (R1, R2) relative to the rotor by another rotary mechanism (46) of the centrifuge and has a rotary head receiving unit (80) for at least one sample container or at least one sample container receptacle (100, 110), with the rotational axis (R1, R2) of the rotary head (30) being inclined relative to the drive axis (A) of the rotor, the rotary head receiving unit (80) being designed to receive an elongated sample container receptacle (100, 110) or an elongated sample container, and the longitudinal axis of the sample container receptacle (100, 110) introduced into the rotary head receiving unit (80) or the longitudinal axis of the sample container introduced into the rotary head receiving unit (80) extending perpendicular to the axis of rotation (R1, R2) of the rotary head (30) or being oriented at an angle ranging between more than 0 and less than 90 relative to the axis of rotation. According to the invention, at least one connection region (52) is provided to which at least one damping mass (54) can be selectively attached either in a releasable manner or, by means of a fixing element, in a permanent manner for operation.

A clamping system for a planetary ball mill includes a base, a clamping lid, including a clamping mechanism configured to secure a grinding container between the base and the clamping mechanism, and a lid configured to pivot with respect to the base from a closed position to an open position, wherein in the open position the grinding container is removable from the clamping system. The system further includes a rotatable arm configured to pivot between a first and second position, wherein in the first position the rotatable arm prevents the clamping lid from rotation to the open position. The clamping system also includes a balancing system having a first counterweight, with a linkage system being coupled between the first counterweight and a carrier plate of the planetary ball mill, the linkage system allowing the first counterweight to move with respect to a rotational axis of the carrier plate.

A milling assembly for a ball mill has a housing for refining and separating a substrate and a collection vessel for retaining the refined substrate. The housing includes, in vertical order, a lid, at least one milling vessel for receiving milling balls, and a screen with a refining section and apertures. The collection vessel is releasably mounted to a bottom end of the housing. The housing has an orifice arranged therein. The orifice has a valve for selectively allowing gas to pass between an outside and an inside of the housing in an open position of the valve and to seal the housing against the outside in a closed position of the valve. The milling vessel includes a taper for receiving a sealing screw.
