Kason offers a variety of anti-blinding devices that increase production by dislodging near-size particles from apertures of the screen. 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.
At top, rubber wiper blades handle fibrous material that would otherwise become entangled in brush bristles or wrap around serrated edges. Rubber blades allow oversize particles to pass by the rotating blade, and are also effective in liquid/solids separations.
At center, integral air brushes keep screens clean when processing with fine meshes that would be susceptible to damage or abrasion by mechanical anti-blinding devices. Air enters at the end of the hollow drive shaft and exits through multiple air nozzles, blowing the screen clean.
At bottom, brushes are flexible, and maintained approximately 1/16" to 1/8" (1.6mm to 3.2mm) away from the screen surface to prevent damage, while allowing desired particles to pass easily through the screen openings.
Kason Centrifugal Sifters are available with integral bag dump stations, with or without dust collectors. Normally configured for installation at mezzanine level, they afford a sufficiently low deck height for operators to dump sacks and other containers, while allowing material to discharge into conveyors, process equipment or storage vessels below.Bag dump stations with optional dust hoods draw ambient air and dust from dumping activities onto the exterior of two cartridge filters that derive vacuum from a top-mounted exhaust fan. Dust
accumulated on the filter's exterior surfaces is dislodged by overcoming continuous negative pressure within the cartridge filters, with positive pressure introduced in short blasts on a timed cycle by pulse jet nozzles. Dislodged material falls into the screener while instant resumption of negative pressure collects any dust generated by the filter cleansing operation.
The Bag Dump Station components are constructed of stainless steel and finished to industrial, food, dairy and pharmaceutical standards.
Kason twin centrifugal sifter configurations are designed for applications requiring greater capacity than a single high-capacity unit can provide. These duplex units are equipped with a splitter to evenly divide the flow of incoming material, regardless of feed rate.

All Kason centrifugal sifters are available designed, constructed and finished to industrial, food, dairy, and pharmaceutical standards including FDA, 3-A, BISSC, EEC and others. Sanitary screeners generally offer one or more of the following features:
Kason centrifugal sifters for pharmaceutical applications are available with the options listed above, and in miniature sizes (shown) ideal for screening, scalping, de-lumping and dewatering small batches of pharmaceutical powders. In less than one minute and with no tools, the unit's end plate, cylindrical screen and
All Kason Centrifugal Sifter models are available in belt drive(top) and direct drive(bottom) configurations.
