摘要： PROBLEM TO BE SOLVED: To efficiently cool fine and coarse aggregates and to enhance the rate of operation of a cooling air feeder by providing an air sending control means and cooling the fine and coarse aggregates by one cooling air feeder. SOLUTION: When a concrete manufacturing apparatus is operated, cooling air is sent to a fine aggregate cooler 1 from a cooling air feeder 8 and when the concrete manufacturing apparatus is stopped, cooling air is sent to a coarse aggregate cooler from the cooling air feeder 8. By this constitution, the rate of operation of the cooling air feeder 8 is enhanced. When atmospheric temp. is high, cooling air is also sent to the fine aggregate cooler 1 even when the concrete manufacturing apparatus is stopped and, therefore, not only coarse aggregate can be cooled but also the fine aggregate cooler main body can be held to predetermined temp. The fine and coarse aggregates can be efficiently cooled to be fed to a batcher plant 5.

摘要： PROBLEM TO BE SOLVED: To efficiently cool a coarse aggregate by sending an air flow from an air feed device to the inner bottom part of a storage tank from the air blow aperture of an air blow duct and circulating the air flow through a void between individual coarse aggregates stored in the storage tank. SOLUTION: The coarse aggregate cooling facilities comprise a storage tank 7 which has a gate 11 at the bottom part and stores a coarse aggregate internally, an air blow duct 21 which is arranged an inner bottom part of the storage tank 7 and has an air blow aperture 26, an air feed device 38 which feeds an air flow at a low temperature or a low humidity to the air blow duct 21 and many lumpy materials 40 which cover the whole air blow duct 21 and are piled up at the inner lower part of the storage tank 7 in such a manner that their stacked elevation becomes gradually lower toward the gate 11. In this case, the air flow at a low temperature or a low humidity originating from the air feed device 38 is sent to the inner bottom part of the storage tank 7 from the air blow aperture of the air blow duct 21 and further is circulated into a void between the coarse aggregates stored in the storage tank 7 from a void between the lumpy materials piled up in the storage tank 7. Thus the coarse aggregate is cooled.

摘要： PROBLEM TO BE SOLVED: To improve the cooling efficiency of aggregates by a method wherein an upper part dispersing device for dispersingly falls the charged aggregates over the whole surface of the dispersing device is provided just below the aggregate charging port. SOLUTION: An upper part dispersing device 14 is arranged just below the aggregate discharging port 6a of the aggregate charging device 6 and, at the same time, above dispersing devices 7. The predetermined amount of aggregated 5 is cut out and charged through the aggregate charging port 6a of the aggregate charging device 6 to the upper part dispersing device 14. The charged aggregates 5 are dispersed with a plurality of blades and fall through the peripheral part of aggregate dispersing members and a plurality of blades and fall through the peripheral part of aggregate dispersing members and a plurality of through holes to below an aggregate falling passage 3 so as to scatter over almost all the surface of the uppermost stage dispersing device 7. The aggregates 5 dispersingly charged from the dispersing device 7 collide against cushioning members 10 so as to be dispersed finer and fall to bellow aggregate falling passages 3. Then, the aggregates cool through the contact with the low temperature and low humidity air flow sent through air supplying ports 15a and 15b and accumulate on an aggregate discharging. As a result, the degree of dispersion of the dispersing device 7 is improved, resulting in allowing to efficiently cool the aggregate.
