South Korea is a resource-dependent country that relies on the import of most metal resources. Therefore, we should save resources through recycling. In particular, the recycle rate of non-ferrous metals is very low. This is due to the limitations of the recycling technology currently in use. To overcome these limitations, non-ferrous metal recycling studies using laser induced breakdown spectroscopy are underway. In this paper, we will discuss an automatic metal classification system that receives metal information from a laser-induced breakdown spectrum and classifies a metal scrap by material. Currently, sorting systems use non-contact pneumatic systems. Compared to the contact method, the system is durable and is controlled at high-speed. This is because the system does not directly contact the metal scrap. Therefore, we will study how to effectively use the flow rate by modeling the pneumatic system.

韩国是一个依赖资源的国家，依赖于大多数金属资源的进口。因此，我们应该通过回收来节省资源。特别是有色金属的回收率非常低。这是由于当前使用的回收技术的局限性所致。为了克服这些限制，正在进行使用激光诱导击穿光谱法的有色金属回收研究。在本文中，我们将讨论一种自动金属分类系统，该系统从激光诱导的击穿光谱中接收金属信息，并按材料对金属废料进行分类。当前，分拣系统使用非接触式气动系统。与接触方法相比，该系统具有耐用性并可以高速控制。这是因为系统不会直接接触废金属。所以，
