Abstract
A screening device (1) comprises a first compartment (3) for receiving solid particulate material, a second compartment (5) for receiving screened particulates from said first compartment (3), a perforated wall (7) separating the first (3) and second (5) compartments from each other for screening the solid particulate material into at least two particulate size-dependent fractions, and a gas permeable layer (21) for fluidization of particulates in said first compartment (3). The first compartment (3) is provided with a solid particulate material inlet (9) located at a first end (22) of screening device (1), and a particulate material outlet (11) located at a second end (24) of screening device (1), with perforated wall (7) extending from first end (22) to second end (24) of screening device (1), enabling simultaneous transport and screening of at least a portion of said solid particulate material.
