Powder sifters automatically remove foreign objects

| By Mary Page Bailey and Gerald Ondrey

GS centrifugal sifters (photo) automatically capture and remove foreign objects from granular and powdered product streams to prevent contamination and safeguard downstream equipment. Installed at the silo, bulk-bag discharge station or other storage unit, GS sifters pass the product stream through a rotating mesh screen sized to allow on-specification material to continue downstream while rocks, metal parts, bulk bag pieces and other foreign objects are blocked and diverted for analysis and disposal. Contaminants are safely removed, product quality assured, and downstream equipment protected from damage. The system’s rotary sieves are offered in a choice of carbon steel, 304 stainless steel or 316 stainless steel with a dust-tight housing and a range of surface finishes to meet sanitary or hazardous-environment requirements. The sifters come with screens ranging in mesh sizes from 100 to 4,000 μm and a removable basket assembly for safe, complete screen cleaning. — Gericke USA, Somerset, N.J.
