The upper and lower screens are readily changed, or the entire unit disassembled for thorough wash down, by loosening all quick-disconnect clamps and the band clamps that connect housing sections, then activating the Air-Lift device to separate the sections as required.
A tangential inlet along the horizontal centerline of the central chamber prevents material from impacting screens at 90° angles. Gradual changes in flow stream direction minimize breakage of oversize foreign material and subsequent material contamination, and reduce screen breakage significantly.
The unit is equipped with “ball tray” anti-blinding devices to dislodge near-size particles from apertures in the upstream side of upper and lower screens, and is intended to remove oversize particles from plastic resin, flour, starch, sugar, and numerous food and chemical products gently, at ultra-high rates. Applications include loading and unloading of trucks and railcars, and conveying of material between process or storage areas.
Offered in 48″ (1219 mm) and 60″ (1525 mm) diameters, the twin-screen machines are available to 3-A, FDA, BISSC and other sanitary standards.
