DeDuster® Removes Electrostatic Charged Dust

Pneumatic conveying of plastics pellets and regrind generates fine dust particles due to friction and velocity. Plastics are good insulators of electrical current, and can build a reasonably high potential charge by the conversion of mechanical energy to static electricity. Due to electrostatic charging, the dust particles stick to the pellet surfaces. These dust particles can cause various unwanted side effects at the molding or extrusion process, such as black spots, blurry surfaces, weak spots and others. Therefore, this dust should be removed before processing of the pellets.

Pelletron has developed various types of DeDusters® for removal of the electrostatic dust. All DeDusters® are equipped with electromagnetic coils that generate a magnetic flux field. One or more electromagnetic coils are located at the product inlet or outlet of the DeDuster®, which produce a low level electromagnetic flux field that covers the entire cleaning area, called wash decks. The wash decks are provided with a series of slots and holes. Pressurized wash air flows through the slots accelerating the pellet toward the end of the deck into the venturi chamber. The holes create jets of air lifting the pellets, and release the dust, lifting it upward. This combination of electromagnetic flux field and air flow effectively removes fines. Pelletron offers DeDusters® in sizes 5 kg/h up to 100 t/h. DeDusters® build very low and can be installed easily on top of IMM’s, Extruders or under silos.

Pelletron has its headquarters in Lancaster, Pennsylvania, USA and a European subsidiary located in Bodnegg/Allgäu, Germany. The company maintains a network of sales and service representatives around the world.

Pelletron Corporation was founded in 1987 to address the need for a dust removal system to aid in the plastic manufacturing process.

The Kinetic Gravity DeDuster®, used a magnetic flux field to disrupt the electrostatic charge between contaminants and pellets, and a patented air wash deck to separate and remove those contaminants. The dedusting process improved product quality, saved production time and reduced scrap.

In 2003, the company began to expand into the pneumatic conveying field. In 2010, pelletroneurope was established in Bodnegg, Germany, to better address the needs of the global market. The company continues to develop and patent various new DeDuster® systems, components and conveying technologies, and today is a well-established supplier for pneumatic conveying systems and components in the dry bulk handling industry.

Pelletron Corporation’s highly experienced Bulkmatology® team has many years of knowledge in building Engineered Conveying Systems that meet the unique and individual needs of customers in a variety of industries.
