DRY SEPARATION METHOD FOR VOLCANIC EJECTA SEDIMENTED MINERAL, DRY SEPARATION APPARATUS FOR VOLCANIC EJECTA SEDIMENTED MINERAL, FINE AGGREGATE AND VOLCANIC GLASS MATERIAL
PROBLEM TO BE SOLVED: To provide a dry separation method for volcanic ejecta sedimented mineral capable of enhancing the yield of fine aggregates with a density of 2.5 g/cmor more by improving a conventional method for regulating the particle size of normal shirasu.SOLUTION: An air stream classification apparatus comprises: a classifier group for coarse grain recovery having at least two cyclone classifiers, which remove gravel contents of 5 mm or more particle diameter from volcanic ejecta sedimented mineral to make a normal temperature or high temperature air stream transport the remainder and are connected to a circulating air stream path; a cyclone classifier for fine grain recovery coupled with this cyclone classifier group; and a bag filter for fine powder recovery coupled with this cyclone classifier group. The air stream classification apparatus recovers coarse gains with the cyclone classifier group for coarse grain recovery, fine grains with the cyclone classifier for fine grain recovery, and fine powder with the bag filter for fine powder recovery, thereby recovering fine aggregates from the recovered coarse grains.SELECTED DRAWING: Figure 1
