Centrifugal screeners are mainly used in food processors for sorting out potential material contaminants. These can also be used for special purposes when trying to quickly deal with the sorting of lots that are suspected to be contaminated. Essentially, a centrifugal screener is designed in a format where the screen is mounted in a fixed fashion and fed via a screw auger. The feed meets a rapidly rotating paddle or series of beater bars encased in the center of the screener, and it is forcefully launched toward the waiting screen for classification.
