The Russell Gated Outlet

The Russell Gated Outlet™ is a pneumatically controlled gate located inside the outlet of the sieve deck. It can be inflated to become a barrier or deflated to allow contamination to ejected, providing complete control of product discharge. This is ideal for applications where there is very little oversize or when product is discharged too quickly resulting in loss of good product. Available in a food grade material as well as high wear polyurethane this device can seal against gravity fed dry powders and liquids up to a head of 1″ (25.4mm).
