摘要： PROBLEM TO BE SOLVED: To provide a continuous type mixing plant for continuously manufacturing concrete by continuously accurately metering respective materials at the time of, for example, suitably continuously manufacturing concrete and requiring manufacture of the concrete of high quality, and sending it to a mixer. SOLUTION: A plurality of types of aggregates are continuously metered and supplied from continuous aggregate supply means 13, 14 and 15, and carried on a conveyor belt of a main belt conveyor apparatus. Then, total amount of the respective aggregates on the belt is continuously measured by a detecting means installed at a predetermined position, and a signal is output from the means. And, mortar is continuously supplied onto the belt by a continuously constant rate supply unit 16 while controlling to feed back according to the signal. Then, these materials are continuously input to a mixing box unit 20 disposed directly under a delivery end of the main belt conveyor apparatus 12, and dropped by their own weights through a plurality of deformed passages continuously changed in sectional shapes from an inlet toward an outlet and substantially vertically extended to be mixed.

摘要： PURPOSE:To produce cooled aggregate in easy improvement of an ordinary producing equipment of concrete by partitioning aggregate in order which is held in an aggregate bin and convergently spraying the cooling material for only the aggregate introduced into an aggregate cooling chamber of the lower part and cooling this aggregate. CONSTITUTION:An intermediate cover 3 having an inverted pyramidal shape is provided to the part of a flex point in which an aggregate bin 1 is changed into a hopper part from a drum part having uniform diameter so that aggregate 2 descends by gravity. Spray nozzles 5 of cooling material are annularly arranged in the position wherein they are not brought into contact with the aggregate 2 descending from an opening 4 of the lower end of the intermediate cover 3 and with the crest of aggregate 2 temporarily stagnated in an aggregate cooling chamber 7. Therefore the thermal efficiency of the cooling material is made sufficiently high because only the aggregate 2 introduced into the aggregate cooling chamber 7 can be convergently cooled by the cooling material sprayed from the spray nozzles 5.
