本考案は金属検出装置に関し、更に詳細には原
料や材料あるいは製品中に不要な金属片が混入し
ているとき、その金属片を検知して効率的に除去
するために用いられる金属検出装置に関する。[Detailed description of the invention] (Field of industrial application) The present invention relates to a metal detection device, and more specifically, to detect unnecessary metal pieces when they are mixed in raw materials, materials, or products. The present invention relates to a metal detection device used for efficient metal removal.
