In-line pneumatic quick-clean twin centifugal sifter

July 4, 2019   Don Horne


A new Model TWIN XOB-PS-SS PNEUMATI-SIFTER Ultra High Capacity dual centrifugal sifter from Kason Corporation de-agglomerates and screens bulk materials in-line with dilute-phase pneumatic conveying systems at ultra-high rates.

Rated up to 14.5 psig (one barg) positive pressure and 14 in. (356 mm) vacuum, it delivers the capacity of two independent high-output sifters, but in less floor space.

A feed splitter evenly divides the flow of incoming material into two horizontally-oriented cylindrical screening chambers operating in parallel. A shaft within each screening chamber rotates a helical paddle assembly that accelerates the radial movement of particles and soft agglomerates against and through the screen. On-size particles pass through apertures in the screens and discharge through a cone-shaped chute, while oversize particles are ejected via a manual or automatic valve into a sealed, quick-release receptacle.

Each of the twin screening chambers features a cantilevered shaft with two, externally-mounted bearings between the screening chamber and motor drive, eliminating the need for a third bearing on the hinged overs end plate. The design allows all internals to slide freely from the shaft ends for cleaning, screen changes, or inspection. Wide spacing between the bearings, a large diameter shaft, and a flexible shaft coupling combine to prevent vibration, even at high speeds under heavy, imbalanced loads.

Available in compliance with FDA, 3-A, BISSC, EEC and other U.S. and European sanitary standards as well as ATEX compliance, the sifter is constructed of stainless steel finished to sanitary standards with thread-free internals, quick-release fittings and optional Clean-in-Place (CIP) nozzles, making it suitable for food, dairy, pharmaceutical and contamination-sensitive industrial applications.

Nylon, monofilament, woven wire, perforated plate or wedge wire screen cylinders are offered to maximize throughput and screen longevity for a diversity of sifting applications.
