Lightweight de-duster for injection moulding processes
Pelletron, Lancaster, PA, has introduced the C-20, a completely new DeDuster® design developed specifically for injection moulding processes. Removing dust and streamers prevents the creation of black or weak spots in finished products and results in reduced scrap rates and higher quality parts. The C-20 weighs 9kg and requires only 240mm for installation between the hopper loader and inlet hopper of an injection moulding machine. It features stainless steel construction, 220V operation and only consumes 3.4-5m3/h compressed air at 1.5-2 bar pressure. It 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.
As with other models in the mini-DeDuster Series, the product inlet has an integrated agitator to reduce bridging and the Venturi design maximises dust removal performance and minimises 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 atmosphere. Pelletron’s European head office is in Bodnegg, Germany. www.pelletroneurope.com
