Abstract (en)

[origin: EP0806245A1] The screw centrifuge for the separation of solids and liquids from a mixture comprises a rotating drum (10) and a coaxial screw (11), rotating at a different speed, with a liquid exit (13) and a solids exit at the other end. Apart from the liquid drain (13), a further drain (16) is provided which is closed by a spring loaded piston (19) at high rotational speeds and opened at low speeds. The piston acts in a radial direction and at right angles to the drain.
