PROBLEM TO BE SOLVED: To provide a method for aggregating shredder dust which prevents shredder dust from scattering when the shredder dust is transported and charged into a furnace in recycling the shredder dust, as a source of iron, which is generated when wastes such as wasted automobiles, wasted electrical products and construction wastes are processed by a shredder facility.SOLUTION: The method for aggregating shredder dust includes: a mixing step of mixing the shredder dust collected by the shredder facility for collecting iron scraps from the wastes, a binding agent and water added so that a water content ratio of the mixture thereof after adding the water is adjusted to 25 mass% or lower; a granulating step of forming a granule 3 from the mixture obtained by the mixing step; and a rolling step of manufacturing an aggregated matter 4 that is aggregated by rolling the granule obtained by the granulating step and regulating a grain size of the granule. |
