New Quick-Clean centrifugal screener

A new Centri-Sifter^® centrifugal sifter from Kason Corporation features a hinged end cover and three-bearing shaft that cantilevers for quick removal of internal components.

External roller bearings are located at the motor end of the shaft and on a hinged cover at the discharge end for maximum support and vibration-free operation. When the end cover is hinged open, the shaft becomes a cantilever supported by a third externally mounted roller bearing located between the motor-end bearing and material feed point, allowing internal components to slide freely from the opposite shaft end.

The new sifter is intended for food, dairy and pharmaceutical applications requiring thorough wash-down, as well as general chemical applications involving frequent screen changes/inspections or runs of multiple materials with no cross contamination.

Dry or moist bulk solid material is gravity-fed into the feed inlet and redirected into the cylindrical sifting chamber by means of a feed screw. Rotating helical paddles within the chamber continuously propel the
material against the screen, while the resultant, centrifugal force on the particles accelerates them through the apertures. In addition to sifting, scalping and dedusting of dry bulk materials, the screener can break up soft agglomerates and/or dewater moist solids or slurries. Oversized particles and trash are ejected through a discharge spout.

Hinged end cover provides access to the cantilevered shaft end, allowing rapid removal of the cylindrical screen and helical paddle assembly for thorough washdown.
