Abstract

The invention relates to a separator comprising a separator housing with an inlet spiral for separating air which opens tangentially into an annular separating chamber and is divided into a plurality of delivery channels which lie one above the other, as well as a basket-shaped separator rotor disposed centrally and with a vertical axis in the separator housing and a guide vane ring which surrounds the latter with a radial clearance. In order that this separator on the one hand has a high effectiveness of separation between oversize material and fine material and on the other hand facilitates a sufficiently broad grain size distribution of the fine material, the overall shape of the separator rotor is that of a cone which tapers downwards.
