Pneumatic Conveying of Plastic Pellets

Fox Venturi Eductors are used for pneumatic conveying of plastic pellets in dilute phase systems. Is a maintenance-free pneumatic conveying solution of interest at your plant?

Fox venturi eductors are installed at hundreds of plastic compounders, reprocessors and recyclers since 1963—installed directly under extruders, pelletizers, and screeners. They pneumatically convey virgin and filled pellets with no degradation, angelhair, or fines, and are particularly useful to eliminate rotary valves when conveying glass-filled, fiberglass-filled, or abrasive pellets. Filled pellets can cause frequent failures with rotary airlocks—which is why hundreds of ceramic-lined eductors have replaced rotary valves at plastic compounders. When quick product or color changes are necessary, Fox clean-in-place (CIP) eductors are used for quick, tool-free clean out to avoid cross contamination.

Fox eductors are used to handle plastic flakes, regrind, and shredded plastic waste at recycling plants, usually installed directly under grinders and screeners. Such irregularly shaped plastic flakes cause jams and failures within rotary airlocks, but are no problem with venturi eductors.
