Surface moisture factor uniform treatment manner and its device null of the aggregate in the freshly mixed concrete

摘要

PROBLEM TO BE SOLVED: To mix aggregates to be used to uniformize the surface water ratio of the whole by circulating extracted aggregate to a supply means through an extraction means, stockyard and carrying means to again supply the same to a plant main body. ;SOLUTION: The gate of a storage tank 2 is opened to pass fine aggregates through a weighing machine 4, a bifurcated chute 5, an extraction conveyor 6, a supply belt conveyor 8, a distribution belt conveyor 9, a stock yard 10, a drawing-out belt conveyor 11 and a feed belt conveyor 12 to again guide the same to the storage tank 2 and this operation is repeated a plurality of times. By this constitution, the fine aggregates are mutually mixed by the falling action of fine aggregates at the connection parts of the respective belt conveyors and the falling storage action of the aggregates in the storage tank 2 and the stock yard 10 and the surface water ratio of the fine aggregates is uniformized.;COPYRIGHT: (C)1997,JPO
