The invention pertains to a method and a device for classifying splinters and wood chips. Splinters and wood chips accumulating in a saw mill are usually subjected to a classification process, i.e., the initial mixture of splinters and wood chips of different sizes is separated in accordance with particle size or settling velocity in a large-scale separation process. The inventive device consists of a centrifugal classifying unit, a countercurrent classifying unit, a separating funnel for the coarse fraction and a separating cyclone for the fine fraction. A gas or a gas mixture is circulated in the system by means of a blower. It is tangentially introduced into the lower classifying chamber, initially flows through the countercurrent classifier, through the gaps between the blades of the centrifugal classifier and then into the separating cyclone before being returned to the blower.
