Operating principle

The separator is usually integrated into a telescopic loading pipe: The product to be cleaned is fed gravimetrically from a silo, through the loading pipe and through the separator. The product is dispersed within the separator, with air counterflow principles harnessed to ensure that dust is cleanly separated from the pellets. The separated dust is extracted in the top area of the separator, with the air.
