Abstract
A centrifugal separator has a centrifuge rotor (,), which is rotatable about a vertical axis (x) of rotation and has at least one outlet (,) around the periphery for intermittently discharging a separated product. The separator has a casing (,), which encloses the rotor, and a space (,), delimited by the rotor (,) and an inner surface of a wall forming a part of the casing. The space (,) is arranged to receive the product from the outlet and has an outlet passage (,) for conveying the product from the space. The inner surface has a first surface portion (,), located at the level of the outlet and extending inwardly from a second surface portion (,) of the inner surface. The second surface portion is located below the first surface portion and extends around the rotor downwardly and inwardly with respect to the axis (x). The outlet passage (,) is located below the maximum diameter of the second surface portion.
