Separator functional principle: How Does a Separator Work?

Using the hydraulic ejection mechanism, the separator opens at the outermost part of the centrifuge housing where the solids collect. After the solid phase has run off, the separator closes again. This happens in a few tenths of a second. The separator is typically driven by a V-belt or flat belt drive. This depends on the size of the separator.
