Zusammenfassung:	PURPOSE:To provide an environmentally benign equipment improved in effi ciency and suppressed in developing noise and dust. CONSTITUTION:Air mixing jet devices 26, 26' are provided to convey with a high-speed jet original concrete 21, 16A freed from reinforcement 12, and solid/liquid separators 25, 25' are set up along the down stream side of the devices. Thus, aggregates 21', 16' separated from the cement and cement cured products having been adhered to can be reclaimed and reclaimed aggregates improved in properties can be obtained. Besides, development of noise and dust, conventionally experienced, can be reduced, resulting in environmental protection. Furthermore, conventional postprocesses such as washing reclaimed aggregates can be omitted, improving efficiency.
