Abstract

A screw centrifuge including a drum having a rotor, the drum having two axial ends and a horizontal axis of rotation, and a screw arranged in the drum and configured to rotate relative to the drum at a speed different from a rotation speed of the drum. Also included is a bearing device located at each axial end of the drum and configured to bear the drum. Each bearing device includes a housing and a pair of cantilevers extending in opposite directions away from the housing. Further included is a pair of spring elements associated with each bearing device and configured for sprung support of the drum. Each spring is arranged between one of the cantilevers and a frame, the spring elements being located at each axial end of the drum.
