To provide a dry process separation method for volcanic ejecta deposit mineral, which can facilitate improving the conventional particle size regulation method of normal Shirasu and increase the yield of fine aggregate with density of 2.5 g/cmor more.SOLUTION: An air flow classifier comprises: a cyclone classifier group for recovering coarse grains, which removes a gravel fraction with a grain diameter above 5 mm from volcanic ejecta deposit minerals, makes the remainder transported by room temperature or high temperature air flow, and includes at least two cyclone classifiers connected to a cycling air flow path; a cyclone classifier for recovering fine grains, which is coupled to the cyclone classifier group; and a bag filter for recovering fine powder, which is coupled to the cyclone classifier. Using the air flow classifier, the coarse grains are recovered by the cyclone classifier group for recovering coarse grains; the fine grains are recovered by the cyclone classifier for recovering fine grains; the fine powder is recovered by the bag filter for recovering fine powder; and thereby fine aggregates are recovered from recovered coarse grains.SELECTED DRAWING: Figure 1
【課題】従来の普通シラスの整粒方法の改良を図り、密度が２．５ｇ／ｃｍ３以上の細骨材の収率を高めることができる火山噴出物堆積鉱物の乾式分離方法を提供する。【解決手段】 火山噴出物堆積鉱物から粒径５ｍｍ超の礫分を除去し、残部を常温又は高温の気流に搬送させ、循環する気流経路に接続された少なくとも２個のサイクロン分級機を有する粗粒回収用のサイクロン分級機群と、このサイクロン分級機群に連結した細粒回収用のサイクロン分級機と、このサイクロン分級機に連結した微粉回収用のバグフィルタとを有する気流分級装置により、粗粒回収用サイクロン分級機群にて粗粒を、細粒回収用サイクロン分級機にて細粒を、微粉回収用バグフィルタにて微粉を回収し、回収された粗粒から細骨材を回収する。【選択図】図１
