The pellcon3 is a new conveying process based on three major process components: Strandphase, Pellbows, and DeDuster. Strandphase is a technology for gentle conveying of granular products. Moderate velocities prevent breakage and attrition of the conveyed product, keeps the generation of dust at a low level, and prevents the creation of long angel hair. It does not need special pipe supports or additional steel construction. It does not create fine micro-dust, seen in dense-phase systems, or long streamers, created in dilute-phase systems. In many cases, pipe diameters are smaller than those in dense-phase systems. As a result, investment costs for large-scale Strandphase systems are lower than slow-motion dense-phase systems. Pellbow is a patented pipe elbow whose design resembles a standard short-radius elbow with a large expanded chamber between the inlet and discharge of the elbow. The soft impact of pellets in the slurry zone and the low wall friction eliminates the creation of streamers. Its pressure loss is only slightly higher than that of standard long- and short- radius elbows. The design eliminates the build-up of product within the elbow. A complete purge is accomplished simply by using the same conveying air volume and pressure. DeDuster is the dust and angel hair removal unit. Regardless of conveying method used, friction is generated by the velocity and pressure. This results in attrition of the conveyed product. The unit removes dust particles providing high-quality resin with remaining dust contents below 30PPM. Existing dense- and dilute-phase systems may be upgraded to incorporate pellcon3 technology.
