The new Vibroscreen® Flo-Thru low profile screener from Kason Corp. classifies bulk material into three fractions at high rates. It employs two screening decks, and two unbalanced-weight gyratory motors mounted on opposing exterior sidewalls of the unit, instead of one motor positioned beneath the screening chamber, reducing minimum height requirements significantly. The Flo-Thru design is offered in diameters from 18 to 84 inches and available to 3-A, FDA, BISSC and other sanitary standards, as well as to UL, ATEX, CSA and CE electrical standards. Quick-disconnect clamp ring assemblies allow removal of screen frames for inspection, cleaning and screen changes. An optional Air-Lift device pneumatically raises either of the upper two screen frames, enabling one operator to rapidly perform what was previously a two-person task, depending on screen diameter.
