High-capacity powder sifting

The Dinnissen Process Technology XS4 Sifting Concept has been designed for the effective and reliable monitoring of powdered substances for contamination such as residual packaging materials, metal particles, stones, grains and chunks. Even large quantities of powders can be monitored quickly and reliably.

Thanks to the variety of sieve cylinder sizes available, the XS4 can be integrated with practically any new or existing (pneumatic) transport system such as bulk transporters, silos, unloading installations and processing techniques.

The basis of XS4 Sifting is a centrifugal sieve. A specially fitted feeding system is used to introduce material to the sieving chamber, where it is spun around by rotating blades. Just like in a centrifuge, fine powder particles pass through the sieve while larger particles are immediately transferred to the back of the chamber. With the right combination of rotor speed, sieve size and length, practically any desired result can be accomplished. Enormous capacities, ranging from 15 up to as much as 70 t/h, can be achieved and even the finest of powders (between 5 and 200 µm) can be processed at speed.
