Separators (Separator Centrifuges)

This type of separator centrifuge possesses cylindrical rotating bowls fitted with several concentric cylinders nested within each other through which the liquid being clarified is cascaded. Chamber separators are primarily used for clarifying liquids whereby the separated solids must be removed manually.

Nozzle separators (disc centrifuges)are characterized by how the separated solids are separated. Solids are separated continuously and fully automatically through nozzles in the bowl wall. These bowls possess built-in disc stacks that increase the equivalent clarification area which helps separate liquids into thin layers. Nozzle separators are in particular used for clarifying suspensions possessing high solid contents.

In contrast to chamber separators, a solid-wall disc separator (disc centrifuge) possesses a so-called disc stack which contains up to 200 stacked discs to increase the equivalent clarification area by several factors. The space available for collecting the separated solids, however, is not as large as in chamber separators so that solid-wall disc separators are primarily used for separating two liquids of different densities (purifier or concentrator) containing very few solids . The separated solids must also be removed manually as is the case with chamber separators.

Self-cleaning disk separators (disk centrifuges) distinguish themselves from the above solid-wall disk separators by how the separated solids are discharged. The solids are removed intermittently through openings in the bowl walls which in contrast to nozzle separators are only intermittently cleared by so-called pistons. Self-cleaning disc separators may be used both for clarifying (clarifier) and separating (purifier or concentrator) fluids.
