Abstract
A selected sampling of powder granules is fed penumatically from an on-line tube to a separator in which granules are separated from the air and transferred to an endless conveyor in a single layer. The selected granules are inspected for metallic foreign particles and thereafter for moisture ratio of the sampled power granules, and number and size of colored foreign particles or the like while on the conveyor.
