Separator functional principle: How Does a Separator Work?
The separator, or disc centrifuge, is a vertically arranged centrifuge. It is used for separating and clarifying liquids. In a disk stack separator, solid-liquid mixtures or liquid-liquid mixtures are separated by centrifugal force. Compared to a decanter centrifuge, the separator differs significantly in its technical design and application.

With dry grinding, these mills often work in a closed cycle. A scheme of the conical ball mill supplied with an air separator is shown in Fig. 2.13. Air is fed to the mill by means of a fan. Carried off by air currents, the product arrives at the air separator, from which the coarse particles are returned by gravity via a tube into the mill.
