Abstract
In a screening device for sorting granular material with at least one rotatable rod basket and a downstream fine material separator a cyclone-type eddy separator is attached with the smaller diameter of its housing cone in order to draw off the screening gas flow charged with fine material and flowing out due to twisting energy in such a way that the rod basket screening device and the separator form a compact unit. A submerged pipe is located in the center of the cyclone-type eddy separator for drawing off the screening gas flow freed of fine material. At least one opening is provided for discharging the fine material at the periphery of the eddy separator housing.

A screening device for sorting granular material with at least one rod basket having a rotor rotatable about an axis and located in the screening housing with turbo elements distributed across a circumference of the rotor, the screening housing having inlets and outlets for screening gas, material to be screened, coarse material and fine material, whereby the outlet for a drawing-off of the screening gas flow charged with the fine material is an opening located at least one axial end of the rod basket in the screening housing comprising:
- a. at the screening housing opening for drawing off the screening gas flow charged with fine material, a cyclone-type eddy separator is attached with a smaller diameter of its housing cone, so that the rod basket screening device and the separator form a compact unit,
- b. in a center of the cyclone-type eddy separator there is a submerged pipe for drawing off the screening gas flow freed from the fine material, and
- c. at a periphery of the eddy separator housing there is at least one opening for discharging the fine material.
A screening device for sorting granular material comprising:
- at least one rotatable rod basket located in a screening housing and comprising a rotor rotatable about an axis,
- the rod basket having turbo elements distributed around a circumference of the rotor,
- the screening housing having inlets and outlets for screening gas, an inlet for material to be screened, an outlet for coarse material and an outlet for fine material,
- the outlet for the screening gas comprising the outlet for the fine material and being located at the axis of the rotor of the rod basket in the screening housing,
- a cyclone-type eddy separator having a cone shaped housing being attached with a smaller diameter of the housing cone directly to the screening housing screening gas and fine material outlet, so that the rod basket screening housing and the eddy separator form a compact unit,
- a submerged pipe being located along a center axis of the cyclone-type eddy separator to draw off screening gas flow freed from the fine material, and
- at least one opening for discharging the fine material located at a periphery of the eddy separator housing.
