Zusammenfassung:The present invention provides a device and a method for manufacturing granules. The device for manufacturing granules includes: a settling tank in which molten metal is settled; a connection unit including a pump, wherein one side of the connection unit is connected to the settling tank; and a circulation tank connected to the other side of the connection unit. The settling tank includes: a spray nozzle unit; and a tundish installed in the upper part of the spray nozzle unit. The molten metal is discharged by the tundish, and water is sprayed at high pressure by the spray nozzle unit and the pump. Therefore, granules of crude metal are manufactured. According to the present invention, the device for manufacturing granules can improve productivity and workability of a hydrometallurgy process which is a follow-up process by casting the molten metal of the high temperature generated by a high-temperature reducing fusion process of a submerged arc furnace (SAF) into the crude metal of a granule form rather than a bulk form. 본 발명은 금속 용탕의 침전이 이루어지는 침전조; 펌프가 구비되고, 일측이 상기 침전조와 연통되도록 형성된 연결부; 상기 연결부의 타측과 연통되는 순환조;를 포함하고, 상기 침전조는, 분사 노즐부 및 상기 분사 노즐부 상부에 배치된 턴디시를 구비하고, 상기 금속 용탕이 상기 턴디시에 의해 출탕되고 상기 분사 노즐부 및 상기 펌프에 의해 고압 수분사가 이루어짐으로써 조금속 그래뉼이 제조되는, 그래뉼 제조 장치 및 제조 방법을 제공하며, 이에 의하면, 서브머지드아크로(SAF)의 고온환원용융 공정을 통해 생성된 고온의 용탕을 벌크 형태가 아닌, 그래뉼 형태의 조금속으로 주조함으로서 후속 공정인 습식 제련 공정의 작업성과 생산성을 향상 시킬 수 있는 효과가 있다.
