Prater Centrifugal Sifter Case Studies

The combination of high centrifugal force and blade spreading action reduces binding problems, even when handling materials that tend to flake or agglomerate due to fat or moisture content.

Prater Rota-Sieves® are ideal for removing foreign material (i.e. insects, plastic, string), sifting, scalping, and classifying.
