Abstract

In a method for separating heavy particles from a particulate material, the material is introduced in a settling chamber (1) to which a carrier air flow (F2) is supplied for entraining the material while heavy particles contained therein fall to the bottom of the settling chamber (1). The material is introduced in the settling chamber (1) as a downwardly-directed flow of material (F1) through an inlet (2), and is removed from the settling chamber (1) in an upwardly-directed flow of material and air (F3) through an outlet (3) located beside the inlet. Compressed-air jets (S) directed obliquely towards the downwardly-directed flow of material are blown into the settling chamber (1) to decelerate the flow of material and spread it towards the outlet (3). The carrier air flow (F2) is blown into the settling chamber to encounter the decelerated, spread flow of material from below. A device for implementing the method as a settling chamber (1) with a downwardly-directed inlet (2) and an upwardly-directed outlet (3) located beside the inlet. A first means (10, 11) is designed to blow compressed-air jets (S) obliquely towards the inlet (2). A second means (5) is designed to blow an upwardly-directed carrier air flow into the settling chamber (1) on a level below the first means (10, 11).
