Abstract (en)
The invention provides a dynamic separator for pulverulent materials, particularly cement, of the type incorporating rotary drums (3,6) traversed by an air stream acting as the separating medium, characterised by comprising a pair of rotary drums (3,6) arranged separately in series one above the other, each of said drums being traversed by an air stream fed independently into the separator and towards each drum through a spiral duct (4,7) with its inlet and outlet tangential, so that each air stream in passing through each drum causes the formation of two separate particle size fractions, namely a fine fraction which leaves from said tangential ducts and a coarse fraction which descends into the separator, the separator hence producing a total of three particle size fractions. <IMAGE>
