Abstract (en)
[origin: US5120431A] A pneumatic centrifugal separator comprises guide vanes disposed along the generatrices of a fictitious cylinder having a vertical axis, the guide vanes being adapted to impart to a gas stream entering the fictitious cylinder a rotary motion about the vertical cylinder axis, and a rotor coaxially positioned in the interior of the fictitious cylinder, the rotor being equipped with a first set of vertical blades distributed uniformly along the periphery of the fictitious cylinder and a second set of blades disposed between the blades of the first set and the cylinder axis. A gas stream and particulate material to be sorted is introduced between the guide vanes and the rotor, and the gas stream charged with particles of dimensions smaller than predetermined dimensions and sorted out of the particulate material is drawn out of a central outlet. The second set of blades is arranged to guide the streams of gas coming through channels between adjacent vertical blades of the first set to the central outlet.
