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.

The present invention relates to a container for a stirrer used in a stirrer stirring objects through a centrifugal force. The container for the stirrer includes a container body of which the top is opened and in which a receiving space is formed, an outer lid coupled to the top of the container body, and a crushing unit including a supporting member disposed in the receiving space, and a crushing member extending outward from the supporting member and crushing and stirring the objects received in the receiving space. Thus, nanoparticle-sized objects can be rapidly crushed and stirred without agglomeration.

A method of automated preparation of a sample material for a chemical or compositional analysis, comprises (i) arranging the sample material in a receptacle (7), (ii) storing the sample inside the receptacle (7) in a conditioning cabinet (3), (iii) grinding the sample material by way of a ball mill apparatus (2), wherein the ball mill apparatus (2) comprises an extraction container (23), at least one grinding element provided in the extraction container (23) and an agitator (21) adapted to move the at least one grinding element relative to the extraction container (23) when the sample material is placed in the extraction container (23), (iv) placing the sample material together with the receptacle (7) in the extraction container (23), and (v) grinding the receptacle (7) together with the sample material by agitating the extraction container (23).

A rotary milling system includes a body rotatable about its longitudinal axis and pivotable about a pivot axis that is transverse to the longitudinal axis. The system includes an interchangeable discharge grate and a solid cover for attaching to an open end of the body. The discharge grate includes a plurality of holes through which milled product can pass while grinding media is retained. The body is pivotable to a vertical orientation, where the covers can be changed, and to a horizontal orientation where grinding can be performed with the solid cover attached or discharge can be performed with the discharge grate attached. The discharge grate is sealed to a discharge housing during discharge via an annular seal, where the discharge grate and body are rotated relative to the fixed discharge housing. The discharge grate can include a deflector portion that deflects milled product away from the annular seal.

The present invention relates to a polishing tank (100) with a metal sleeve (110) and a removable insert modular system (120) configured to be inserted into said sleeve and to be removed from said sleeve.
