<p><P>PROBLEM TO BE SOLVED: To provide a building waste sorting method for separating and sorting building waste, which is crushed into a predetermined size by pretreatment, based on specific gravity difference to recover only excellent regenerated aggregate for the purpose of again putting the building waste mixed with impurities and the regenerated aggregate to practical use. <P>SOLUTION: The building waste crushed into the predetermined size is charged in the liquid within a sedimentation tank to be separated based on specific gravity difference but the specific gravity of the liquid is allowed to become a reference specific gravity value not higher than the specific gravity of the element to be recovered but not lower than the specific gravity of another element to sediment only the element to be recovered to the lower part of the sedimentation tank to sort the same. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
