Process-4th Stage


4th Stage -Reduction to Fine Granules
The minus 1/4” granules are stored in a bin and fed to each powderizer via an independent feed screw. The powderizers have a number of screen options for variable product sizing. Depending upon desired end product sizing, a screen would be selected and installed into each H.O. powderizer. Once the material is reduced sufficiently it is removed from the powderizer via vacuum pneumatics and conveyed on to fiber separation where a “spalling‑screen” followed by a gravity-bed separator, each equipped with aspirators, efficiently remove the remaining fiber. The clean material is then fed to a classification screen to do final.
