Abstract: A decanter centrifuge, for separating a sludge into components, with a rotor and a scroll arranged inside the rotor. The rotor is configured at least partially as a solid bowl rotor with at least a cylindrical section and a conical section. The rotor includes a first end face, concluding the cylindrical section of the rotor, with a first diameter, and a second end face, concluding the conical section, with a second smaller diameter. A flange with one or multiple openings is arranged on the first end face, wherein one or multiple weir plates are fastened to the flange which at least partially cover the openings and are arranged to set a liquid level inside the rotor and form a first radial outlet edge for letting out a liquid at the first end face. The weir plates include an elastically deformable coating on their side facing the flange.

Abstract: Calender having a frame having a roll stack therein and a lower deflection control roll as the lowermost roll of the roll stack. The lower deflection roll has a sleeve supported on a bracket having opposed ends. The lower deflection control roll further has a deflection control device configured to secure the bracket against rotation. The deflection control device is further configured to operate in the direction of a center place of the roll stack. The calender further has a pair of bearing blocks, each bearing block being configured to hold a respective end of the bracket. Each bearing block is adjustable by a respective loading device. The calender further includes a pair of pivoted arms each having a proximal end and a distal end, the proximal end swivelly connected to the frame, and the distal end connected to a respective bearing block.
