Separating device, agitator bead mill and method for classifying product mixtures

Abstract

The invention relates to a separating device for classifying product mixtures consisting of at least two different components. The separating device comprises a shaft, a stationary screen unit and at least one classifying rotor. At least particles of the at least one component of the product mixture can pass through the screen unit up to a determined diameter. The classifying rotor comprises a support plate mounted on the shaft in a non-rotational manner, as well as one or more attachments that are mechanically coupled to the support plate. The attachments influence a flow behavior of the product mixture in the region of the screen unit. The one or more attachments can be fixed in different positions on the support plate relative to the rotating shaft such that, depending on the respective positions, different flow behaviors of the product mixture can be achieved in the region of the screen unit. The invention also relates to an agitator bead mil having a separating device and a method for classifying product mixtures by means of a separating device.

Description

technical field [0001] The invention relates to a separation device, an agitator ball mill and a method for classifying product mixtures according to the features of the preambles of claims 1 , 8 and 12 . Background technique [0002] The invention relates to a rotor finger of a rotor which is arranged around a separation system in the region of the product outlet of an agitator ball mill. Agitator ball mill is a kind of equipment used for coarse grinding, fine grinding and superfine grinding, or for homogenizing grinding materials. The agitated ball mill consists of a grinding chamber with an agitator in which the ground material is reduced to size by means of grinding media. [0003] Agitator ball mills usually consist of horizontally or vertically arranged, approximately cylindrical grinding vessels. This agitator ensures vigorous movement of the grinding media with suitable stirring elements. The agitator ball mill is filled through an opening in or adjacent to an end...

Problems solved by technology

However, these slats and brushes have the disadvantage that they act directly on the separating sieve and can press the product or grinding medium into the mesh of the separating sieve, thereby clogging the separating sieve

Furthermore, in the case of very abrasive materials, there is a risk of faster wear or damage to the separating screen
