The present invention relates to a circulation method for reusing the waste water generated in the device and the selection process of removing the wet screening the debris to the construction waste recycling by efficient and environmentally sound as makeup water. Supply conveyor 70, the present invention is to supply an intermediate transfer lysate material of construction waste for this purpose; The feed is located in the lower end of the conveyor 70, a balancer 19 for balancing the construction waste is falling through the feed conveyor (70); The construction and number of the first foreign matter of the waste on the one side to separate and remove selective pressure chamber 11 and the second number of pressure chambers (11a) are formed respectively separately, the chain scraper (13) for discharging the construction waste sorting other side mounted inside the body and in which the water is the water storage (10); Punching screen 12 of the mobile switch to the riding action and one for cleaning and removing foreign materials of construction waste through the balancer 19 to be dispersed inside the immersion body (10); It said first number of pressure chamber 11 and the second number of pressure chamber (11a) is provided on both sides (17a) a first rubber Cylinder (16) (16a) and the second rubber Cylinder (17) for generating a water pressure of .; And second rotary drive shaft (20) (20a) by driving the motor 23 in a state installed on both sides of the body is in the inverter 24 to the acceleration (加減), offset in mutually opposite directions on the outer peripheral surface of the drive shaft It is hanssangsik installed first rubber Cylinder (16). (16a) and the second rubber Cylinder (17). (17a) a cross-intersection the first cam (22), (22a) and the second cam 21 for pushing (21a); And installing the other inclined to the inside of the body, first the construction waste is moved foreign matter is removed from the punching screen by a drive chain scraper (13) for discharging a first vibrating dewatering screen 50 of the motor 14; Controlling the water level at the top of one side and is provided with a foreign matter discharge port role Wear (wier) (25) and on the wear of the second vibrating dewatering screen to rotate by the drive of the third motor 18 of the body 51 It consists of; scraper (15) for discharging the foreign matter. The present invention constructed as described above has a simpler structure and function can handle a clean, easy to 200mm below more clearly remove the foreign materials to a relatively large construction waste in the range of 150mm or less to more than 5mm in volume, the less foreign matters of 1% It can be removed by screening, and makeup can be eco-friendly by allowing work to be used to re-circulate the used muddy water and it will be a help as well because this greatly improved the quality and reliability of products.
