Abstract (en)
[origin: US2001020597A1] Centrifugal action type pneumatic separator comprising a rotor with a vertical axis provided with vanes regularly distributed over its periphery, guide blades disposed about the rotor and a housing containing the rotor and the guide blades and provided with inputs for the air and for the material to be graded, with an evacuation conduit for the air laden with the fine fraction of the material and with an output for the coarse fraction, with the air penetrating the rotor at its periphery via the channels (15) formed between the vanes, and flowing inside the rotor towards the evacuation conduit. To be able to modify the grain size distribution of the particles in the finished product, the air flowing in the rotor is divided into at least two separate streams, and the rotor is equipped with means (28) for adjusting the speed and/or the flow rate of at least one of the streams.
