Abstract: A solid bowl centrifuge includes a rotatable drum having a cylindrical portion with length L1 and a conical portion with length L2, which, when added, give the length LT of the drum. A screw is arranged in the drum and is rotatable relative to the rotatable drum with a differential speed. At least two drum bearings for supporting the drum in the housing are spaced apart with a spacing LL. A spacing LL of the drum bearings for supporting the drum relative to one another is less than the length LT of the drum.

Abstract: A self-emptying separator includes solids discharge openings each having a piston valve that is moveable moved into an opening position and into a closing position in a fluid-actuated manner. The emptying mechanism also has a control assembly assigned to the piston valve and controls the opening and closing movements of the latter. The control assembly also includes a control device and a metering device for metering and dispensing the amount of liquid required for the opening process. The metering device has a metering element that is movable in a metering chamber and which subdivides the metering chamber into a fluid chamber and a pressure chamber intended to be supplied with compressed air. The metering device has an adjusting system for metering the amount of liquid required for the opening process in the fluid chamber. The adjusting system has a measuring device that operates based on a fluidic measurement principle.

Abstract: A separator includes a preassembled drive and rotation system unit having an outer ring flange portion and a drive frame having an inner ring flange. The outer ring flange portion of the preassembled drive and rotation system unit is vertically connected to the inner ring flange of the drive frame. A rotatable drum is placed onto the preassembled drive and rotation system unit, in the drum at least one paring disk is arranged in a paring chamber, and one or more stacks each having one or more stackable intermediate elements are arranged between the inner ring flange and the outer ring flange portion in order to set an axial relative position at least between the drive frame and the drive and rotation system unit.

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 clarifying a flowable starting product of solids using a self-emptying centrifuge in continuous operation in a centrifugal field in the rotating drum. A continuous draining of at least one clarified liquid phase occurs and solids emptying occurs repeatedly via outlet openings that are intermittently opened and closed. The emptying of solids from the drum of the centrifuge is initiated, the speed of the drum of the centrifuge is reduced, the solids are emptied from the solids collection chamber of the drum after lowering the speed of the drum, and the emptying of the solids from the drum is ended.

Abstract: A solid bowl screw centrifuge includes a housing and a rotor rotatably mounted in the housing. The centrifuge has a rotatable drum having an axis of rotation, the drum having a cylindrical section having a length L1 and a conical section having a length L2. The centrifuge also has a first inlet for feeding a suspension to be processed into the drum and a liquid outlet arranged in the cylindrical section of the drum and a solids outlet arranged in the conical section of the drum. A screw is arranged in the drum and rotatable at a differential speed relative to the rotatable drum, the drum and the screw together forming the rotor. The centrifuge also a second inlet for supplying an additive to a solid phase within the drum.

Abstract: A separator includes a housing that is stationary during operation and designed as a tank having at least two openings. A drum located inside the housing can be rotated about an axis of rotation, the drum having an axis of rotation and at least one opening. A gap is formed at least in sections or continuously between the drum and the housing. The separator also includes a support and drive device having at least two support and/or drive units, which keep the drum suspended inside the housing, supported, and/or set in rotation. One of the support and/or drive units is a first magnetic bearing that at least axially supports the drum and to keep it suspended. At least one other of the support and/or drive units is axially supports the drum.
