DRY TYPE SEPARATION METHOD OF VOLCANIC EJECTA MINERAL DEPOSIT, DRY TYPE SEPARATOR OF VOLCANIC EJECTA MINERAL DEPOSIT, AND METHOD FOR MANUFACTURING FINE AGGREGATE AND VOLCANIC GLASS MATERIAL
PROBLEM TO BE SOLVED: To provide a dry type separation method of a volcanic ejecta mineral deposit, that can increase the yield of fine aggregate with a density of 2.5 g/cmor more, and thereby improve a conventional method for regulating particle size of ordinary Shirasu.SOLUTION: A gravel fraction is removed from a volcanic ejecta mineral deposit and the remainder is fed to at least one kind of a wind-force sorter 11 selected from among a circulation type wind-force sorter and a blowing-up type wind-force sorter, in order to be sorted into a coarse grain fraction and a fraction other than the coarse grain fraction. The coarse grain fraction is fed to a specific gravity difference sorter 21 of an air table type, which blows air from below toward a porous plate while oscillating the porous plate inclined at a predetermined angle from a horizontal direction, and then a selection from an upper end of the porous plate is recovered as fine aggregate.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礫分を除去した残部を、循環式風力選別機及び吹上式風力選別機から選ばれる少なくとも一種の風力選別機１１に供給して、粗粒分と、粗粒分以外とに二分し、該粗粒分を、水平方向から所定の角度で傾斜させた多孔板を振動させつつ下方から多孔板に向けて送風するエアテーブル式の比重差選別装置２１に供給して、該多孔板の上端から選別されたものを細骨材として回収する。【選択図】図１
