<P>PROBLEM TO BE SOLVED: To provide a regeneration treatment method of a regenerated aggregate, which realizes inexpensive and effective grinding rubbing, suppresses remarkable noise and dust, and does not damage the aggregate. <P>SOLUTION: In the regeneration treatment method of a regenerated aggregate which is obtained by crushing waste concrete in which mortar is adhered on the surface of aggregate, a process in which the regenerated aggregate and water are thrown in a first rotating pan type mixer 10 which performs kneading by carrying out level rotating of a first blade 12 prepared in a tub-like first vessel 11 to rotate the first blade 12, the mortar is removed from the aggregate, and muddy water in which the removed mortar is mixed with water is discharged from an exhaust port 13 by rotating the first blade 12; and a process which pours water in the first vessel 11 are repeated, and thereby the mortar is made to remove from the aggregate, and the aggregate which has been removed is regenerated as a first regenerated material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
