Sorting Apparatus of Collected Metal Powder in Laser Deposition Process

摘要

The metal powder classifying device recovered in the laser lamination process according to the present invention is a metal powder classifying device for classifying a mixed powder in which the metal powder recovered in the process of performing the laser lamination process and foreign substances are mixed. A plurality of through-holes having a set size are formed to fall the mixed powder having a particle size smaller than the size of the through-hole to the lower side, and the mixed powder having a particle size larger than the size of the through-hole is collected and sorted, and the front It includes a plurality of fractionation units inclined downward toward the plurality of fractionation units, and the plurality of fractionation units are arranged in a vertical direction so that the mixed powder passing through the passage hole of the upper fractionation unit falls to the fractionation unit on the lower side, and from the upper part to the lower part. It is formed so that the size of the through hole gradually decreases toward the sorting unit.
