Abstract (en)
[origin: EP1826315A2] A cylindrical separating screen (1) with a vertical axis is arranged for radial inward flow from an inlet (3). The separated material flows to an outlet (4) for acceptable material and a drain (5) for rejected material. The screen is surrounded by a rotating drum or cage (8) fitted with a large number of foils, e.g. of aerofoil shape, that promote inward flow of the suspension. An independent claim is included for a flow-promoting device consisting of a drum fitted with foils. The drum has preferably between 2 and 10 foils per square meter and the thickness of the drum and foil assembly is no greater than 10% of outer diameter of drum (8).
