APPARATUS FOR STABILIZATION TREATMENT OF RECYCLED AGGREGATES

摘要

PURPOSE: A neutralizing apparatus of movable circulation aggregate is provided to promote carbon dioxide gas contact neutralization of circulation aggregate by contacting the circulation aggregate and carbon dioxide gas more frequently after spraying the carbon dioxide gas from a mixer shaft. CONSTITUTION: A neutralizing apparatus of movable circulation aggregate includes a circulation aggregate inlet, a gas supply hole and a mixer. The mixer(13) promotes neutralization of the circulation aggregate. The mixer includes a rotary shaft and an agitating vane. A carbon dioxide gas supply flow path is formed inside the rotary shaft. A carbon dioxide gas discharge nozzle is formed on the exterior of the rotary shaft. The carbon dioxide gas is sprayed through the carbon dioxide gas discharge nozzle.
