Downsized deduster targets injection molding

A new deduster has been designed specifically for the injection molding process, promising to remove dust and streamers from resin and prevent black or weak spots in finished products.  The new patent-pending DeDuster from Pelletron weighs only 20 lb (9 kg) with a height of 9.5 inches (240 mm).

Downsized deduster targets injection molding

A new deduster has been designed specifically for the injection molding process, promising to remove dust and streamers from resin and prevent black or weak spots in finished products.  The new patent-pending DeDuster from Pelletron weighs only 20 lb (9 kg) with a height of 9.5 inches (240 mm).

Installed between the hopper loader and inlet hopper of an injection molding machine, the new DeDuster reportedly provides high cleaning efficiency with results comparable to Pelletron's existing P1 DeDuster. The new model features stainless steel construction, 110- or 220V operation and only consumes 2-3 cubic ft/min (3.4-5m3/hr) compressed air at 20-30psi (1.5-2bar) pressure.Pelletron DeDuster

The design of the C-20 builds upon the mini-DeDuster Series, featuring a product inlet with an integrated agitator to reduce "bridging" of pellets. In addition, the Venturi design maximizes dust removal performance and minimizes carryover of good product into the dust collector. The unit operates with compressed air supplied directly from the plant air supply instead of from a separate fan, and inside the deduster, compressed air is split into two streams for optimal removal of dust and streamers, as 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 then 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.
