ABSTRACT:
The invention relates to an air separator for sifting material suspended in a flow of gas having course material and fine material by using a sifting wheel which rotates in a sifting chamber and which has blades fixed on the external periphery thereof. The blade channels are cross-flown radially from the outside by gas containing the suspended fine particles. The oversized particles are rejected before reaching he internal end of the blade canal. The flow of fine particles is guided through the blade channels in a forced manner in a plurality of consecutive layers in the direction of the axis of rotation. The arrangement in layers of the flow of fine particles after it leaves the blade channels remains in place until it leaves the sifting chamber.
