MILLBURN, NJ — A new Centri-SifterTM Twin Ultra-High Capacity Centrifugal Sifter introduced by Kason Corp. matches the capacity of two individual High Capacity screeners within a smaller footprint, while cantilevered three-bearing shafts allow rapid sanitizing, according to Henry Alamzad, president.Dry or moist bulk solid material is gravity-fed through a feed splitter to evenly divide the flow of incoming feed material into the two horizontally-oriented cylindrical screening chambers which operate in parallel. A shaft in each screening chamber rotates a helical paddle assembly that accelerates the radial movement of particles against the screen. On-size particles pass through apertures in the screens and fall through a cone-shaped discharge chute, while oversize particles are propelled
through the open end of the screen cylinders and ejected through a discharge spout.
Each of the screening chambers features a sliding 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 sliding 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 for thorough wash-down.In addition to sifting and scalping of dry bulk materials, the screener can
break up soft agglomerates and/or dewater moist solids or slurries.
The screener is constructed of stainless steel finished to 3-A, FDA, BISSC, and other sanitary standards required for food, dairy, and pharmaceutical applications, as well as contamination-sensitive chemicals.
