Abstract: A separator for centrifugally processing includes a rotatable drum having at least two drum parts, which can be rotated relative to one another at a screw thread. A drum tool is designed to open and close the drum by rotating the drum parts screwed together by the screw thread. The drum tool includes a retaining element attachable to the one drum part, a driver element attachable to the other, relatively rotatable drum part, and at least one rotation device for the relative rotation between the retaining element and the driver element together with the drum parts. The retaining and driver elements each having two or more points of engagement for the rotation device. The points of engagement are symmetrically arranged in such a way that forces produced by the rotation device produce a torque for the relative rotation of the drum parts, but no resulting force acting on the screwed drum parts on one side is produced.

Abstract: A method for processing a flowable product using a centrifuge includes pretreating the flowable product so that particles in the flowable product are increasingly attracted by electrically charged components, feeding the flowable product into the disc stack, generating an electric charge on the discs of the disc stack, and separating the charged particles from the flowable product within the disc stack under the influence of electrostatic attractive forces and a centrifugal field.

Abstract: A method for monitoring, controlling, and/or regulating the operation of a centrifuge, in particular a separator, during the centrifugal processing of a product, in particular when clarifying a product and/or when separating a product into different liquid phases. The centrifuge has a drum which can be rotated by a drive spindle, a drum mounting, and a drive motor. Force measurements are performed using one or more force sensors and analyzed, and an output is provided in the event of a deviation from a specified behavior and/or the analyses are used for or during the control and/or regulation of the operation of the centrifuge.

The point on the outlet channel which is narrowest in terms of the cross-section is formed by the inlet opening itself and the cross-section of the outlet channel is not reduced at any point over the axial length of the outlet channel in the outlet direction.

Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.
