In the process of continuously spirally conveying the coal gangue by the vibrating feeding mechanism 2, the impurities such as steel wire ropes, wood and dust mixed in the coal gangue float in the water, and then the impurities are removed by the filter 102 arranged in the water circulation mechanism 1. The coal gangue is sequentially conveyed upward to the first conveying mechanism 3 by the vibrating feeding mechanism 2. Since the conveying belt of the first conveying mechanism 3 is provided with a magnet, it can adsorb the magnetic metal and the alloy containing magnetic metal, and after the magnetic metal and the alloy containing magnetic metal run to the lower side, the shovel plate 401 on the material box 4 shovels the magnetic metal and the alloy containing magnetic metal into the material box 4.
