SEPARATOR

The invention relates to a separator having a rotating system having a) a drum that is rotatable during operation and that has a vertical rotation axis (D), b) which has a drum interior chamber (20),c) which is divided into a bottom double-tapered centrifuge chamber (21) and a top double-tapered centrifuge chamber (22), d) wherein the two centrifuge chambers (21, 22) each have solids discharge openings (34, 35), which can be exposed and sealed in the bottom centrifuge chamber (21) by a piston valve (26) and in the top centrifuge chamber (22) by an auxiliary slide (27), wherein e) the mass moment of inertia (JQ) of the rotating system (1) about a transverse axis (Q) extending through the center of gravity (S) of the rotating system of the drum (1), perpendicular to the vertical rotation axis (D), is greater than the mass moment of inertia (JD) of the rotating system (1) about the vertical rotation axis (D) of the rotating system. 本发明涉及分选机，其具有回转系统，该分选机包括：a)在运行中可旋转的、具有竖直旋转轴线(D)的滚筒，b)该滚筒具有滚筒内腔(20)，c)该滚筒内腔分成双锥形的下部
