Dense phase pneumatic conveying, feeding and weighing system

August 6, 2008

Dynamic Air recently provided a major rubber producer a complete dense phase pneumatic conveying system for both unloading and conveying carbon black from rail cars to three large 2000 cubic foot capacity storage silos and then to multiple day bins. Also included were two complete weighing systems for two Banbury mixers. Components included multiple Dyna-Slide high precision air activated feeders and two separate weigh hoppers for each mixer. The Dyna-Slide high precision air activated feeders with a 100-to-1 turndown ratio provide high accuracy. Typical cycle time for weighing up to four ingredients is less than two minutes from discharge to discharge.
