New DeDuster for injection molders

C-20 DeDuster on IMM

Developed for injection molders – the new lightweight DeDuster® made by Pelletron Pelletron, a pioneer in dedusting technology, introduces the C-20, a completely new DeDuster® design developed specifically for injection molding processes. + Excellent cleaning/dedusting results + Low construction height 240mm + Lightweight design 9kg + Low cost investment Removing dust and streamers prevents the creation of black or weak spots in finished products and results in reduced scrap rates, higher quality parts and improved profit. The design: The lightweight C-20 DeDuster® weighs 9kg and requires only 240mm for installation between the hopper loader and inlet hopper of an injection molding machine. The high cleaning efficiency offers results comparable to the P1 DeDuster®, the current product-of-choice for injection molding applications. It features stainless steel construction, 220V operation and only consumes 3.4-5m3/h compressed air at 1.5-2bar pressure. The C-20 DeDuster® is designed for a nominal product flow rate ~20kg/h at 560kg/m³ bulk density. Flow rates up to 30kg/h are possible for products with higher bulk densities. How it works: The design of the C-20 builds upon the features of the proven mini-DeDuster® Series. The product inlet has an integrated agitator to reduce “bridging” and the Venturi design maximizes dust removal performance and minimizes carryover of good product into the dust collector. It operates with compressed air supplied directly from the plant air supply instead of from a separate fan. Inside the unit, the compressed air is split into two air streams for optimal removal of dust and streamers, and an ionizer is used to release the electrostatic bond between the pellets and the dust. The cleaning air blows the removed fines and streamers into two mini-cyclones, which separate them from the air. The separated contaminants are collected in a clear dust collection box and the cleaned air is filtered and released to the atmosphere. For creation of a negative pressure in the entire device, outside air is pulled in through a filter-protected opening.
