DeDuster® Systems

The DeDuster® by Pelletron

Pelletron DeDuster®

The Ultimate Cleaning Technology

The Pelletron DeDuster® was developed as a result of demands for high quality standards in the plastics industry, but the technology can be used for all kinds of granular bulk materials.

  • Remove dust and streamers with one machine
  • Separate and remove electro-statically charged dust particles
  • Fit on injection molding machines
  • Offer low construction height
  • Fit on top of extruders and under silos
  • Reduce remaining dust level after cleaning to < 50PPM


Where Do Fines Come From?

Some dust and contaminants occur naturally in products like minerals, food, tablets and other bulk solids, while others are caused by the way the products are handled.

Impurities in plastic pellets, both fines (dust) and angel hair (streamers), are generated by the friction in conveying lines. Dilute phase systems create large amounts of dust and streamers; the higher the velocity, the larger the amount of impurities. Pipe elbows also cause friction and result in the creation of more dust and streamers. The high pressure in dense phase, or slow motion systems, creates very fine dust due to wall friction and friction between pellets. Temperature, pellet shape and product characteristics can also contribute to the creation of dust.

Why Is Cleaning So Important?

Cleaning bulk solids is important for several reasons.

Food and pharmaceutical bulk solids are cleaned for hygienic reasons and to improve the quality of the finished, packaged product.

Minerals are cleaned primarily to avoid environmental and health problems.

The plastics industry cleans pellets to improve the quality of both the pellets and the finished plastic product.

How it works

Pelletron developed a cleaning machine that combines a variety of air wash principles, plus the revolutionary electro-static flux field feature, and built it with the lowest possible construction height. When electrostatically charged particles enter into the Magnetic Flux Field, the resulting “Lorentz Force” weakens the electro-static bond between fine dust and plastic pellets. This weakening, in combination with the air flow, allows the micro fine particles attracted to the pellet surfaces to be removed.
