Title:
RECYCLED AGGREGATE PREPARATION APPARATUS HAVING ENHANCED CARBON SEQUESTRATION AND BASED ON CRUSHED RETURN MATERIAL, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/240768
Kind Code:
A1
Abstract:
Disclosed are a recycled aggregate preparation apparatus having enhanced carbon sequestration and based on crushed return material, and a method. The apparatus comprises: a screw conveyor, a throw rotor, a screening drum, a material return drum and a carbon dioxide input pipe; the screw conveyor comprises a raw material inlet, a fine aggregate inlet and a discharge port; the screening drum comprises an inner drum and an outer drum, and the throw rotor accelerates and throws aggregate into the inner drum, causing the aggregate to collide and be crushed; the material return drum is sleeved outside of the screw conveyor, the fine aggregate inlet is located in the material return drum, and material return blades of the material return drum drive fine aggregate to be fed from the fine aggregate inlet into the screw conveyor; and an inlet end of the carbon dioxide input pipe is communicated with the interior of the screening drum. The aggregate collided, crushed and shaped, and during this process fully reacts with carbon dioxide, causing the carbon dioxide to be absorbed and sequestered, thereby improving the carbonization of the recycled aggregate and preparing a high-quality recycled aggregate.
