Separator with a double-conical centrifuging chamber

A separator, comprising:

• a rotating system, which comprises a drum with a vertical axis of rotation, wherein the drum is rotatable during operation and has a drum inner chamber, which is subdivided into a lower double-conical centrifuging chamber and an upper double-conical centrifuging chamber,
• wherein the lower and upper double-conical centrifuging chambers each have solids discharge openings, which are openable and closable in the lower centrifuging chamber by a piston slide and in the upper centrifuging chamber by an auxiliary slide,
• wherein a mass moment of inertia of the rotating system about a transverse axis extending through a center of gravity of the rotating system of the drum and which is perpendicular to the vertical axis of rotation is greater than a mass moment of inertia of the rotating system about the vertical axis of rotation of the rotating system,
• wherein the drum inner chamber is subdivided by a conical partitioning plate into the lower double-conical centrifuging chamber and the upper double-conical centrifuging chamber, and
• wherein the auxiliary slide has a double-conical form, and a sealing ring is formed between the conical partitioning plate and the auxiliary slide.
