Now you can produce three value-added products from just one single material stream with a Backers 3-fraction star screen. Pass all material over the coarse deck to break up wet organics, maximizing production and overall screen yield. Create a fourth fraction by adding an optional tipping grid to scalp off the very coarse material; or attach an optional wind sifter to remove plastics and other light contaminants from either or both screening decks. Backers 3-fraction star screens are highly maneuverable, and are available on stationary, wheeled, tracked, or our exclusive wheeled/tracked chassis.
