摘要
PROBLEM TO BE SOLVED: To reduce cost for separating collection of lead beads by separating and collecting the lead beads from lead bead-contaminated soil with a simple procedure.;SOLUTION: In this separating collection method, air is blown by a blowing means 3 against the lead bead-contaminated soil 12 dropping from a straight soil dropping port 13 with a broad width. A lead bead moving region 15 where the lead beads drop receiving air, and a gravel moving region 16 where gravel drops receiving air and blown off to a leeward side of the lead beads, are divided from each other in a blowing zone 11. A top part 20 of a roughly chevron shape part 21 of a separating guide means 8 is located between the region 15 and the region 16. The lead beads of the region 15 are dropped and received in a lead bead collection part 22 on the tilted face 18 of a windward side of the guide means 8, and gravel of the region 16 is blown off toward a gravel collecting zone 23.;COPYRIGHT: (C)2006,JPO&NCIPI
