PRINCIPLE OF OPERATION
| Material is 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. These rotating paddles, which never make contact with the screen, also serve to breakup soft agglomerates. Over-sized particles and trash are ejected via the oversize discharge spout. |

Sift, Scalp, De-lump and De-water Virtually
Any Bulk Solid or Slurry
The Kason Centri-Sifter® is a versatile, high capacity, compact and economical centrifugal sifter used for screening a wide variety of powders or granular materials, including chemicals, plastics and resins, foods, dairy products, pharmaceuticals and biologicals, at high rates. This equipment is the ideal choice for continuous scalping of dry or moist materials, even those that tend to ball or agglomerate as these units de-lump and de-agglomerate while screening. The Centri-Sifter Screener is also extremely effective as a liquid/solids separator.
Broad model range solves
specialized problems
Centri-Sifter centrifugal sifters are designed for gravity-fed applications, and for sifting in-line with pneumatic conveying systems. They are available as single and twin models and low profile units, and offered in a broad range of standard, modified, and custom configurations. All are available with belt drive or direct drive. Units may be freestanding or adapted for easy mounting on new or existing process equipment. On gravity-fed models, a large access door allows inspection and cleaning. In-line pneumatic units offer large ports for inspection. Removable end housings allow rapid cleaning and screen changes. Centri-Sifter separators meet the most stringent worldwide sanitary standards including USDA, FDA, 3-A, and BISSC. Special finishes and materials also make these sifters suitable for biochemical and pharmaceutical applications.
Screen options
The choice of separating media includes nylon and other monofilament cloth, woven wire in selected metals, perforated plate screen, and wedge wire. Wedge wire screens are preferred when sifting large, dense particles with angular shapes, oversize lumps or when it is important that contaminating debris must be prevented from entering processing streams. Kason's wedge wire screens are rugged, durable and provide a high degree of on-stream reliability.
Anti-blinding devices speed production, reduce maintenance
Kason offers a variety of devices that increase production by combating screen blinding. These devices reduce the clearance between the rotating paddle and the cylindrical screen without contacting or abrading the screen. Narrowing the gap between the rotating element and the screen surface enhances screening rates under near size conditions, thereby increasing throughput.
