Embodiment Construction

[0011] figure 1 A sectional view of the upper region of a preferred embodiment of the vibrating mill 1 according to the invention or of the grinding unit 2 according to the invention is shown. image 3 An overall view of the vibrating mill is partially schematically shown. This is a so-called vibrating disc mill. exist figure 1 The grinding unit 2 shown is an assembly which can be excited to vibrate by a special vibration drive connected to the grinding unit, which encloses a grinding chamber 3 which is delimited on the outside by a cylinder-shaped grinding wall 4 . An essentially circular grinding base 5 adjoins the bottom side of the grinding wall during the grinding process. In the illustrated embodiment, a grinding ring 6 and a grinding stone 7 are located on the grinding base, wherein the grinding stone is a round, unbroken solid body in the drawing. The outer diameter of the grinding ring 6 is smaller than the inner diameter of the grinding wall 4 , and the outer dia...

Abstract

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.

Description

technical field [0001] The invention relates to a grinding unit for a vibrating mill, in particular a disc vibrating mill, wherein a grinding chamber is formed in the grinding unit, which is delimited laterally by grinding walls and has a cooling device surrounding the grinding walls . Background technique [0002] Grinding units or vibratory mills of this type are used, for example, during the preparation of samples for the desired analysis (e.g. X-ray-based examination of the contained elements by means of appropriate equipment, such as XRF), where the Specimens made of vibratory, granular abrasives are crushed. Abrasives sprayed into the grinding chamber by a liquid are also conceivable. Samples (such as rock samples, ore, slag, etc.) are mixed with auxiliary materials and ground in a vibratory mill, and then compressed into tablets by auxiliary pressure supply equipment. For the analysis of components, the tablets are sent to the analysis device. The sample must be g...
