Abstract: A centrifuge, in particular a separator, includes a rotatable centrifuge drum with a vertical axis of rotation and a non-rotatable fixed housing with a hood and preferably a solids collector. In the centrifuge, the housing, in particular the fixed hood and/or at least one other part of the housing, have at least one first inner wall and a first outer wall which delimit a first cavity. The cavity is at least partly filled with damping/insulation agents that are solid at a process or ambient temperature. A coolant that has a fluid form at a process and/or ambient temperature can be introduced into the first cavity filled with the solid damping/insulation agents.

Abstract: A separator for the centrifugal processing of a flowable product includes a rotatable drum with a vertical rotation axis. The rotatable drum borders a centrifuge chamber and includes a clarifying arrangement in the drum for clarifying the product to be processed in the centrifugal field. The drum has a separating plane between a drum top part and a drum bottom part. A supply system and the drain system are designed on the drum. The separator also includes a housing in which the drum is arranged, the housing having floor part and a housing shell part connectable to the floor part. A separating plane is likewise designed between the floor part and the housing shell part of the housing. The two separating planes are aligned with each other or there is an offset of less than 250 mm between the two separating planes.

Abstract: A separator for the treatment of a flowable product by centrifugation has a rotatable drum delimiting a centrifuging space. The separator also includes, arranged in the drum, an agent for clarification of a product to be treated in the centrifugal field. The drum includes an outer support and an inner drum arranged in the outer support, and in the agent for the clarification of the product to be processed in the centrifugal field is arranged in the inner drum.

Abstract: A method for processing a product is disclosed. The method includes providing a separator having a rotatable centrifugal drum and a plate assembly arranged in the drum. The product is supplied into the drum. One or more of a solids phase and at least two liquid phases are separated from the product. One or more of the at least two liquid phases and the solids phase is discharged out of the drum. The supplying of the product occurs in one of a continuous and a discontinuous cyclic volume stream performed at a constant cyclic frequency where the constant cyclic frequency has a period duration which is dependent on one or more of the parameters of an inner and outer radius of a plate, an inflow stream in an intermediate space between the plate and an adjacent plate, a plate angle, and a distance of the plate to the adjacent plate.

Abstract: Disclosed is a centrifuge including a rotatable centrifugal drum and a drive spindle to drive the centrifugal drum. The drive spindle is rotatably mounted via a bearing in a housing supported elastically on a machine framework. Further included is a drive device including a drive motor to rotate the drive spindle and a lubricant system to lubricate the bearing. The lubricant system is configured to deliver lubricant from a lubricant supply tank through a lubricant channel into a region of the bearing. An injection device is arranged downstream of the lubricant-supply tank and is configured to deliver the lubricant into the region of the bearing by dispensing quantities of lubricant in temporally discrete pulses with a limited-time air stream. A method is disclosed of directing lubricant into a region of a bearing of the centrifuge as noted above.
