Classifying device for classifying a granular material flow
View Patent ↗A classifying device may be used to classify a granular material flow. The classifying device may comprise a first inlet that allows a first material flow into the classifying device, a second inlet that allows a second material flow into the classifying device, a static classifier, and a dynamic classifier. The static classifier may be positioned such that the static classifier at least partially surrounds the dynamic classifier. The classifying device may comprise a distributing device that is designed in such a manner that it supplies the material flow of the first inlet to the static classifier and the material flow of the second inlet to the dynamic classifier.
1. A classifying device for classifying a granular material flow, the classifying device comprising:
a first inlet for allowing a first material flow into the classifying device;
a second inlet for allowing a second material flow into the classifying device;
a static classifier;
a dynamic classifier, wherein the static classifier is positioned such that the static classifier at least partially surrounds the dynamic classifier; and
a distributing device that is configured to supply the first material flow from the first inlet to the static classifier and to supply the second material flow from the second inlet to the dynamic classifier,
wherein the distributing device comprises:
a first rotatable disk for supplying the first material flow from the first inlet to the static classifier; and
a second rotatable disk for supplying the second material flow from the second inlet to the dynamic classifier.
2. The classifying device of claim 1 wherein the distributing device comprises at least one region that is connected to a housing of the classifying device.
3. The classifying device of claim 1 wherein at least one of the rotatable disks is connected to a driveshaft.
