In the production of meal-fine products by a milling process the milling material generated in a comminuting device is ordinarily separated at the desired grain size in a downstream sifter and the fine material (meal-fine product) obtained here is then separated in the fine material separating device from the sifting air. According to the invention it is proposed to construct the sifter as a V-sifter and to connect this latter, without interposition of the otherwise ordinarily used pipelines, directly with the fine material separating device, preferably an electro-filter.

Milling installation

Two-stage classification of a granular material, in particular a cement grinding feed, is accomplished in two classifiers connected in series in such a way that the separative behavior or the separative action and thus the particle-size distribution of the undersized or finished material coming from the second classifier can be modified with simple resources. Part or all of the oversized material of the second classifier is recycled to the second classifier.

Method and device for two-stage classification of granular material

In order to create a sifting device with integrated static sifter member and dynamic sifter member having at least one rotatably disposed rod basket such that the two sifter members are optimally coordinated so as to operate efficiently, particularly with moist sifting material to be dried, it is proposed in accordance with the invention to have a bypass line leave from the intermediate area between the static member and the dynamic member of the sifting device for drawing off a partial flow of the sifting air flow/sifting gas flow and to supply only the remaining outgoing sifting air of the static sifter member (static cascade sifter or V-sifter) to the dynamic sifter member with the at least one rotatably disposed rod basket.
