METHOD FOR REGULATING TEMPERATURE OF AGGREGATE FOR CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for regulating a temperature of an aggregate for a concrete capable of easily regulating the aggregate to a target aggregate temperature in a suitable temperature regulating time and shortening a concrete manufacturing time. SOLUTION: A sprinkling time required that the temperature of the aggregate in an aggregate storage bottle 2 arrives at a target aggregate temperature when a chilled water of a predetermined temperature is supplied at a predetermined sprinkling amount per unit time is previously calculated by a heat fluid analysis. The chilled water of a predetermined temperature regulated by adding and mixing a temperature regulated water obtained by cooling a part of a natural water to the natural water drawn from the river R is sprinkled for the sprinkling time in the bottle 2 in a predetermined sprinkling amount per unit time by a sprinkler 12 to cool the aggregate 10 in the bottle 2.
