To provide a fractionating device capable of stably fractionating powders such as cement raw materials by a simple configuration. A fractionating devicefor fractionating some of a powder (cement raw material) R falling in a chute (main body), wherein the fractionating device is equipped with a screw conveyorwhich passes through the chute, a part of a casingopening inside the chute, and receives part of the powder from an opening (inlet), and a collision separation member (collision separation rod)which is provided above the screw conveyor in the chute and collides with an object when an object of a predetermined size or larger falls, and prevents the object from falling directly onto the screw conveyor. A rotation shaftof the screw conveyor may be inclined from 5° to 20° with respect to the horizontal plane so that the end of the discharge port side of the screw conveyor is positioned above the other end and may be equipped with a guide memberthat guides the powder falling in the chute in the direction of the opening of the screw conveyor.
