Screening and classification can be done prior to, after, or completely separate from milling, blending, pelletizing and dry granulation.
Toll has numerous 48″ and 60″ screeners. We use them to separate solids from liquids or segregate dry materials into various sizes. Particles as fine as 400 mesh (37 microns) can be screened, with up to 4 screen decks incorporated in one Sweco separator. All finished product can be discharged into a variety of packages.
