Centrifugal separator operates in-line with pneumatic conveyors

A new CENTRI-SIFTER© centrifugal separator operates in-line with dilute-phase pneumatic conveying systems, eliminating the need for cyclone separators and rotary air locks. Rated for positive pressures to 14.9 psig or negative pressures to 14 inches vacuum, the unit separates virtually all free-flowing materials transported by the conveyor, at equivalent capacities.

Rotating helical paddles within a cylindrical screening chamber continuously propel and accelerate incoming particles through apertures in the screen. The paddles, which do not contact the screen, also serve to break-up agglomerated materials. Oversize particles accumulate immediately upstream of a manually- or automatically-actuated valve, which is opened periodically to eject the trash into a sealed, quick-release receptacle.

The sealed unit allows two-minute screen changes and thorough wash down of all smooth interior surfaces, and is available to 3-A, USDA, FDA, BISSC and other sanitary standards.

A wide range of sizes and configurations are offered including low-profile models, twin configurations, and gravity-fed units for sifting, scalping and dedusting, as well as dewatering and de-lumping applications.
