Document Type and Number:
WIPO Patent Application WO/2011/064930
Kind Code:
A1
Abstract:
Deposits such as mortar are efficiently removed while preventing over crushing of recycled aggregate. A method for producing recycled aggregate, which includes a step for crushing waste concrete, a sorting step for sorting the crushed materials to extract the recycled aggregate, and an ore-grinding step for ore-grinding the extracted crushed aggregate to remove the deposited mortar, wherein a step for consecutively emitting abrasive particles and a step for inducing the recycled aggregate to fall to the area where the abrasive particle group is emitted are performed in parallel, and wherein the abrasive particles are brought into collision with the recycled aggregate to remove the deposited mortar.
