Abstract
본 발명은 석분을 이용하여 습식으로 모래를 제조하는 방법에 관한 것으로, 호퍼에 저장된 석분이 진동피더의 속도조절을 통하여 진동스크린으로 일정량 공급되는 석분 이송단계와, 진동 스크린에 이송된 석분은 노즐에 의한 물의 분사를 통해 진동스크린에서 일정 입도를 갖는 모래와 파쇄기로 이송되는 석분으로 분리하는 석분선별단계와, 미분 및 모래가 제거된 순수 석분이 벨트 켄베이어를 통해 파쇄기에 투입후 파쇄기내에서 석분이 파쇄되며, 파쇄기의 로터주속변화에 의해 모래의 입도와 입형을 적절하게 가공하는 모래가공단계와, 파쇄기로부터 가공된 모래가 진동스크린을 거쳐 분류된 후, 노즐을 통해 분사된 물로 세척하고, 세척완료된 모래가 나선형 분급기로 분급되어 벨트 컨베이어로 이송되는 모래세척 단계 및, 나선형 분급기내에서 미분과 함께 오버 플로어되는 물이 미세분말 침전용 탱크로 유입되어 슬러지로 처리토록 함으로써, 건축, 토목 공사용 자갈을 생산하는 쇄석의 부산물로 생성되는 불필요한 석분을 이용하여 일정한 입도를 갖는 모래를 연속적으로 제조할 수 있음은 물론, 모래의 제조시 발생되는 미세한 분말 가루를 용이하게 제거하여 환경오염을 예방하고, 파쇄기의 파쇄효율을 가일층 향상시키며, 자동화 작업에 의해 양질의 인공모래를 저렴한 경비로 제조할 수 있는 잇점이 있다.The present invention relates to a method for producing sand by using the powdered stone, the stone powder transfer step of supplying a predetermined amount of stone powder stored in the hopper to the vibrating screen through the speed control of the vibration feeder, and the stone powder transferred to the vibrating screen to the nozzle Separation step for separating the granules into sand and stone powder transferred to the crusher through the spraying of water by vibrating screen, and the fine powder from which fine powder and sand are removed is put into the crusher through the belt Kenveyer and then The sand processing step of properly crushing the granularity and shape of the sand by changing the rotor speed of the crusher, and the sand processed from the crusher are sorted through the vibrating screen, and then washed with water sprayed through the nozzle, Sand washing step where sand is classified by spiral classifier and transferred to belt conveyor, and in spiral classifier Water that overflows with the powder flows into the fine powder settling tank and is treated with sludge so that sand having a constant particle size can be continuously produced using unnecessary stone powder produced as a byproduct of crushed stone that produces gravel for construction and civil engineering. Of course, it is possible to easily remove the fine powder powder generated during the production of sand to prevent environmental pollution, further improve the crushing efficiency of the crusher, and to produce high quality artificial sand at low cost by automated operation There is an advantage.
