Abstract

Ein Zentrifugalsichter zur Sichtung eines Sichtgut-Trägergas-Gemisches ist mit einem Eingangsteil, einem mit mehreren Abführrohren (8) verbundenen Ausgangsteil und mit einem Kranz von Führungselemente (5, 9) versehen. Die Führungselemente (5, 9) sind von außen nach innen und im wesentlichen radial durchströmt und umschließen einen innen liegenden, axialen Austrittsquerschnitt (17). Der Austrittsquerschnitt (17) ist in mehrere voneinander getrennte Segmente (18) aufgeteilt, und ausgehend von dem Austrittsquerschnitt (17) ist jedes Segment (18) mit einem der Abführrohre (8) verbunden.

Figure 00000001
A centrifugal classifier for classifying a mixture of visible material and carrier gas is provided with an input part, an output part connected to a plurality of discharge pipes (8) and a ring of guide elements (5, 9). The guide elements (5, 9) are flowed through from the outside inwards and essentially radially and enclose an axial exit cross section (17) lying on the inside. The outlet cross section (17) is divided into several separate segments (18), and starting from the outlet cross section (17), each segment (18) is connected to one of the discharge pipes (8).
