In the pulverizing process of dry recycled powder on a mass production scale, pulverizing equipment with a classifying function is required to efficiently obtain a dry recycled powder that does not contain particles with excessive particle diameters. Since the maximum particle diameter tends to increase as the feed rate of raw material powder increases, we focused on the classification method and performed pulverization tests.
