摘要： The invention relates to a dosing device for volumetrically dosing pourable dosing material, preferably pourable sample material, comprising at least one metering unit (3) that is open towards the top and that is preferably shaped like a beaker. The opening edge (22) of said metering unit defines an opening cross-section, and at least one dosing blade (24) comprising a blade edge (25) that is associated with the opening cross-section and that is preferably parallel to said section. The metering unit and/or the dosing blade is/are displaceable in order to obtain a lateral relative blade movement between the metering unit (3) and the blade edge (25). The aim of the invention is to improve said dosing device in an advantageous manner such that a longitudinal guide (26), along which the dosing blade (24) can be guidingly displaced in a transversal manner to the opening cross-section (23), is provided and that maintaining means (34) that are suitable for producing and adjusting in a dimensionally adjustable manner the maintaining force (61) acting upon the dosing blade (24) in relation to the longitudinal guide (26). When the forces (60) that are exerted upon the dosing blade (24), after the stripping process, exceed the maintaining force, the dosing blade (24) is displaced back along the longitudinal guide (26).
摘要翻译： 本发明涉及一种用于体积计量可倾倒计量材料的计量装置，优选是可倾倒的样品材料，其包括至少一个朝向顶部敞开的计量单元（3），并且优选地形状像烧杯。 所述计量单元的开口边缘（22）限定开口横截面，以及至少一个计量叶片（24），其包括与所述开口横截面相关联并且优选平行于所述截面的叶片边缘（25） 。 计量单元和/或定量给料刀片是可位移的，以便在计量单元（3）和叶片边缘（25）之间获得横向相对的叶片运动。 本发明的目的是以有利的方式改进所述定量给料装置，使得纵向引导件（26）沿着横向方向被引导向定位开口横截面（23）移动。 以及适于以尺寸可调节的方式产生和调节相对于纵向引导件（26）作用在定量给料叶片（24）上的维持力（61）的维持装置（34）。 当施加在定剂量叶片（24）上的力（60）在剥离过程之后超过维持力时，定量给料叶片（24）沿纵向引导件（26）向后移位。 本发明还涉及一种包括所述类型的计量装置的样品制备装置以及用于体积计量的给药方法。

摘要： The invention relates to a grinding unit (2) for a vibration mill (1), particularly a disk vibration mill, wherein a milling chamber (3) is configured in the grinding unit (2), the chamber being delimited on the side by a grinding wall (4) and comprising a cooling device (38) surrounding the wall. In order to achieve a practical improvement, the cooling device (38) comprises two or more cooling channels (39) abutting the grinding wall (4) from the outside and disposed circumferentially along at least one common circumferential section of the grinding wall (4), wherein adjacent cooling channels (39) are spaced from each other at least circumferentially in section by a circumferentially extending support projection (41). The support projection (41) supports the grinding wall (4) against a housing (11) surrounding it from the outside. The invention further relates to a vibration mill (1), particularly a disk vibration mill, having said grinding unit incorporated.
