To separate grit from pellets and crumbs PTN supplies three types of sifting machines: sieves with one sieve deck, sieves with two sieve decks (double-deck) and sieves with a gauze cover

Vibrating sieves are used to remove grit and fine particles from the pellet flow. The installations are available in a single-deck or a double-deck version. The latter has three outlets for coarse material, pellets and grit.
