Centrifugal separator - Mode of operation

The liquid to be cleaned flows under pressure tangentially into the cylindrical inlet area of the ZYKLOMAT® hydrocyclone formed with an inlet spiral.

In the subsequent conical section, the flow direction of the suspension is spiral-shaped, whereby the spiral continuously narrows toward the underflow nozzle.

With the tangential inlet the liquid forms a primary eddy near the wall in which the separation of the solid particles takes place under the influence of the strong centrifugal effect. In the process, the particles with a higher specific weight than the liquid are transported out of the primary eddy toward the wall.

The particles slide along the smooth inner side of the ZYKLOMAT® hydrocyclone to the underflow nozzle, where they are separated out of the underflow nozzle with a small quantity of liquid (concentration). As a result of the throttling effect caused by the conical shape, the ZYKLOMAT hydrocyclone forces the liquid eddy to reverse directions before it reaches the tip of the underflow nozzle.

As a secondary eddy spinning in the same direction, the cleaned liquid rises in the secondary eddy to the ZYKLOMAT® upper course. The liquid existing in the upper course of the ZYKLOMAT® hydrocyclone has only a minimal solids content.

A stable air core is located within the secondary eddy which can uniformly aerate the liquid.
