摘要：
A kind of combined separator for gas atomization equipment was designed. The combination of computational fluid dynamics(CFD) simulation and experiment were employed to investigate the separation performance. Based on the separation performance difference between two different structure separators, the coarse and fine particles can be hierarchically collected during the powder preparation process, so that the preparation cycle and the cost of alloy powder for selective laser melting(SLM) can be reduced. The results indicate that the collection efficiency of C1 structure separator for fine alloy particles is lower under the condition of argon flow rate of 400 m3/h and powder flow rate of 1kg/min, while C2 structure separator exhibits a high collection efficiency for fine alloy particles under the same gas atomization condition. These two structure separators in series connection can effectively classify fine and coarse particles, thus the separation treatment cycle in the next process can be shorten. © 2020, Science Press.
