계속하여, 상기 1차파쇄부(100)에 의해 파쇄되는 원료는 2차파쇄부(200)의 샌드밀(210)에 의해 다시한번 파분쇄되어 19㎜이하의 쇄석및 모래상태로 되고, 상기 쇄석및 모래상태로 배출되는 원료는 그 후방의 공정라인 상에 설치되는스크린(230)의 자력선별기(230a)등으로서 이물질을 선별한다.Subsequently, the raw material crushed by the primary crushing unit 100 is crushed once again by the sand mill 210 of the secondary crushing unit 200 to be in the form of crushed stone and sand of 19 mm or less, and the crushed stone And the raw material discharged in the sand state is selected as a foreign matter magnetic separator (230a) of the screen 230 is installed on the process line of the rear.
더하여, 상기 스크린(230)에는 관통공(230b)이 일체로 형성되어 분리되는 미분이 관통공을 통하여 저부에 낙하되고, 상기 스크린(230) 상에 투입되는 폐기물은 진동자(230c)에 의한 진동과 고압의 살수노즐(230d)에 의한 세척작업을 통하여 쇄골재에 부착되는 시멘트 미분을 다시한번 수세토록 한다.In addition, the screen 230, the through-hole 230b is integrally formed to separate the fine powder is dropped to the bottom through the through-hole, the waste injected into the screen 230 and the vibration by the vibrator (230c) Through the washing operation by the high pressure spray nozzle 230d, the cement fine powder attached to the clavicle aggregate is washed again.
그리고, 상기 스크린(230)의 하측면 역시 미분을 수거토록 컨베이어(230f)가 설치된다.And, the lower side of the screen 230 is also provided with a conveyor 230f to collect the fine powder.
상기 스크린(230)을 통과한 원료는 이물질이 완전 제거된 천연상태의 쇄석이나 모래와 실질적으로 동일하게 되어 원료선별분리부(300)에 공급된다.The raw material that has passed through the screen 230 is substantially the same as natural crushed stone or sand from which foreign substances are completely removed and is supplied to the raw material sorting separator 300.
또한, 2차파쇄부(200)를 통과 한후 파쇄된 원료는 스크린에 의해 분리되어 그 일측에 연결되는 컨베이어(310)로서 각각의 야적 장소에 배출되고, 이때 상기 스크린의 하측으로 배출되는 미분은 미분회수수단(330)을 통하여 회수된다.In addition, the raw materials shredded after passing through the second shredding unit 200 is discharged to each yard as a conveyor 310 is separated by the screen and connected to one side, the fine powder discharged to the lower side of the screen is fine powder It is recovered through the recovery means 330.
상기 미분회수수단(330)은, 다단의 침전조(330a)로 구성되어 각각의 침전조(330a)를 통과하면서 중력침강되는 구성으로 포집된다.The differential recovery means 330 is composed of a multi-stage settling tank 330a is collected in a configuration that is gravity settled while passing through each settling tank 330a.
또한, 최후의 침전조에서 회수되는 물은 살수노즐과 연결되는 펌프(330b)에 의해 살수노즐에 재공급되어 순환되도록 하며, 상기 미분은 열원을 공급되면서 스크린(330c-1)을 갖는 건조탈수조(330c)로서 탈수 건조되어 도자기의 원료나 블록등의 코팅재로 재사용토록 된다.In addition, the water recovered in the last settling tank is recirculated to the spray nozzle by the pump 330b connected to the spray nozzle, and the fine powder is supplied to the heat source while drying the dehydration tank having a screen (330c-1) ( 330c) is dehydrated and dried to be reused as a coating material for ceramics or blocks.
한편, 상기 콘크러셔(150)의 일측의 스크린을 통과한 원료중 일정입도 이하의 원료만이 2차파쇄부(200)를 향하도록 설치되며, 일정입도 이상의 원료는 각각상이한 관통공(130b)을 갖는 개체의 스크린에 의해 선별되어 다양한 규격의 골재 생산이 가능토록 되는 것이다.Meanwhile, only raw materials having a predetermined particle size or less of the raw materials that pass through the screen of one side of the cone crusher 150 are installed to face the secondary crushing unit 200. Raw materials having a predetermined particle size or more have different through holes 130b. It is selected by the screen of the individual having it is possible to produce aggregates of various specifications.
이상과 같이 본 고안에 따르면, 폐콘크리트·폐아스콘·건축폐자재·건축폐기물·혼합폐기물 등을 선별 처리하는 과정에서 발생되는 먼지가 대기중으로 비산되는 것을 방지하여 환경오염을 방지하도록 한다.According to the present invention as described above, to prevent the environmental pollution by preventing the dust generated in the process of sorting the waste concrete, waste ascon, building waste materials, construction waste, mixed waste and the like to the air.
또한, 골재에 혼합되는 이물질을 완벽하게 분리하여 골재의 재활용시 발생되는 강도저하 현상을 방지하도록 하고, 폐건축자재중 골재의 재활용하도록 하며, 다양한 입도를 갖는 골재의 하나의 공정에 의해 선별하도록 하고, 천연골재에 근접하는 양질의 골재를 얻을수 있도록 하는 것이다.In addition, to completely separate the foreign matter mixed in the aggregate to prevent the strength degradation caused when the aggregate is recycled, to recycle the aggregate in the waste building materials, and to sort by one process of aggregate having a different particle size In order to obtain high quality aggregate close to natural aggregate.
본 고안은 특정한 실시예에 관련하여 도시하고 설명 하였지만, 이하의 실용신안등록청구범위에 의해 제공되는 본 고안의 정신이나 분야를 벗어나지 않는 한도내에서 본 고안이 다양하게 개량 및 변화될수 있다는 것을 당업계에서 통상의 지식을 가진자는 극히 용이하게 알수 있음을 밝혀 두고자 한다.Although the present invention has been shown and described with respect to specific embodiments, it is understood that the present invention may be variously modified and changed without departing from the spirit or the field of the present invention provided by the following Utility Model Registration Claims.
