Abstract
Abstract A separator for sorting particulate material has a rotor (1) with vanes (3); static, separately adjustable guide vanes (8,9); a casing (14) defining an inlet duct for material suspended in a conveying gas; an outlet (7) for a suspended fine fraction; and a hopper (12) for collecting a coarse fraction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A separator for sorting particulate material into a fine fraction and a coarse fraction, the separator comprising a rotor (1) with a substantially vertical axis and vanes (3), an adjustable guide vane system (8,9) surrounding the rotor and a housing encasing the guide vane system (8,9) and the rotor and having one or more inlet ducts (14) for the supply of conveying gas and unsorted material, an outlet duct (7) from at least one end of the separator discharging the separated fine material fraction suspended in the conveying gas and an outlet duct (12) beneath the rotor and the guide vane system for discharging the separated coarse material fraction for further treatment, characterised in that the guide vane system consists of two or more guide vane sets (8,9) mounted one above the other and in that the different guide vane sets are separately adjustable.
Claim 2
Dependent Claim
144 words
A separator for sorting particulate material into a fine fraction and a coarse fraction, the separator comprising a rotor (1) with a substantially vertical axis and vanes (3), an adjustable guide vane system (8,9) surrounding the rotor and a housing encasing the guide vane system (8,9) and the rotor and having one or more inlet ducts (14) for the supply of conveying gas and unsorted material, an outlet duct (7) from at least one end of the separator discharging the separated fine material fraction suspended in the conveying gas and an outlet duct (12) beneath the rotor and the guide vane system for discharging the separated coarse material fraction for further treatment, characterised in that the guide vane system consists of two or more guide vane sets (8,9) mounted one above the other and in that the different guide vane sets are separately adjustable.
Claim 3
Dependent Claim
26 words
A separator according to claim 1, characterised in that the guide vanes of each guide vane set have means (15,16) for setwise adjustment of the vanes.
Claim 4
Dependent Claim
34 words
A separator according to claim 1 or claim 2, characterised in that the guide vane sets (8,9) are axially offset relatively to one another and at the same radial distance from the rotor axis.
