Kason Corporation has introduced a quick-clean CENTRI-SIFTER centrifugal sifter with a cantilevered shaft that offers greater screening area and higher capacity than any single chamber model previously offered by the company. Designated model XO-B, the sifter can scalp in excess of 100 tons (90 tonnes) per hour of dry or moist powders or granular material, and de-lump materials that tend to ball or agglomerate. It can also dewater solids-laden slurries at rates exceeding 500 gpm (1900 lpm) depending on application.
As bulk solid material enters the inlet, a feed screw redirects it into the cylindrical sifting chamber where rotating helical paddles accelerate the material, continuously propelling it against and through apertures in the cylindrical screen. Oversized particles are discharged through the end of the screen cylinder into a discharge outlet.
The cantilevered shaft is supported by two bearings at its infeed end. With no bearing at the discharge end, the screen and internal components can slide freely from the shaft through a hinged end cover with no tools, allowing rapid cleaning, screen changes and inspection.
The sifter offers a time-delay function for operator safety, along with safety interlocks on the end cover, side access door and removable feed screw cover.
It is available in carbon steel or 304/316 stainless steel with industrial or sanitary finish, and with electrical systems rated to explosion-proof standards including full ATEX Compliance in Zone 20 environments.
The sifter can be configured for gravity operation or in line with positive or negative pressure pneumatic conveying systems.
According to company president Henry Alamzad, Kason offers the world’s widest range of cantilevered centrifugal sifters, from its flagship XO-B model to its compact CO-SS mini sifter.
Kason also manufactures round vibratory screeners, static sieves, size reduction equipment, mixing and blending equipment and circular fluid bed dryers, coolers and moisturizers.
