Reducing streamers and fines when conveying plastic pellets
In this column, we'll discuss how to handle streamers and fines formed when you pneumatically convey plastic pellets, such as polyethylene and polymer pellets. [Editor's note: Find more information on this topic in Solt's March 1998 column.]
Streamers and fines are types of residue created when plastic pellets are pneumatically conveyed. Streamers have flat ribbon-like shapes as long as 20 feet and as wide as 2 inches. Fines can include dust particles, typically smaller than 120 mesh, and angel hair, slender strings less than 2 inches long and typically hair-thin.
