Fines and fluff filtered with deduster

product13.jpgThe P1 Mini-Deduster can remove dust, fines, fluff, and streamers from resin quantities typical of midsize and small processors. Miniscule contaminants in materials can cause increased scrap, rejected parts, and production delays. Unchecked, the fines, fluff, and dust produced during the migration of material through processing can contaminate the resin, resulting in burn, bubble, or other defects.

The P1 Mini-Deduster processes up to 200 lb/hr of raw material and removes particles smaller than 100 µm.

By using a low-power electromagnetic field created with a flux field generator, the P1 disrupts the electrostatic bond that forms between pellets and any dust contaminants created while conveying raw materials. The system works by using the electromagnetic field to separate the contaminants from the resin, allowing the pellets and the dust to drop down to the primary air-wash deck.

A stream of air lifts the lighter particles above the heavier resin stream. The pellets then pass through a venturi chamber, which regulates the updraft air velocity in order to remove streamers. The smaller contaminant particles are then carried out of the deduster and into a dust collector. Next, the air is filtered and recirculated back to the air-wash deck.

In order to streamline production, molders can install the P1 inline at the feedthroat of a press for seamless filtering of resins, or place the unit offline as part of a regrind and scrap recovery system. The unit requires gravity feed of raw materials and automatically provides even material flow to avoid resin surges.
