주석 폐자원의 재활용을 위한 전처리 및 분급 공정에 대한 연구

다국어 초록 (Multilingual Abstract)

In this paper, tin-waste resources were pulverized and separated by cut-mill and multi cyclone separator, respectively. After the cut-mill process, more than 98% of the Pb-Sn and Sn-Ag-Cu scraps were recovered, and the by-products consisting of metal and oxide could be reused as solder. The separation of pulverized powders was performed using the minimum fluidization velocity depending on the density of the materials. When the flow rate was 21 L/min (70% blower output), it had the highest separation efficiency.
