Pelletron develops new lightweight DeDeuster C-20 for injection molding
Pelletron Corporation, a dedusting technology supplier based in the US, has introduced the C-20, a new patent pending DeDuster design developed specifically for injection molding process.
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. According to Pelletron, 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, 110 or 220V operation and only consumes 3.4-5m3/h compressed air at 20-30psi pressure.
The C-20 DeDuster is designed for a nominal product flow rate of 20kg/h at 560kg/m³ bulk density. Flow rates up to 30kg/h are possible for products with higher bulk densities.
Pelletron says the design of the C-20 builds upon the features of its 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.Pelletron emphasizes that 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.
