Title: 안내판형 볼밀
Inventor: HONG SUNG MIN
IPC: B02C17/06
Filed: 2010-10-25
Abstract: 볼밀은 원통 안에 쇠구슬이나 돌 따위가 들어 있어 부수거나 가루를 낼 물건을 넣고 돌리면 부딪치고 마찰하여 분쇄된다. 기존 볼밀의 분쇄 효율의 한계가 있다. 볼밀의 회전속도가 빨라지면 볼이 볼밀의 내벽을 따라 돌기 때문에 볼밀의 회전속도는 한계를 가지고 있다.본 발명은 볼밀의 회전속도 한계를 없애기 위한 것이다. 볼밀 안에 곡선형 안내판을 설치하여 볼밀의 빠른 회전으로 인한 볼의 내벽에 따라 도는 것을 안내판로 인해 볼이 안내판을 따라 볼밀 밑에 부분으로 떨어지게  
된다. 안내판이 곡선이면 볼과 안내판의 충돌 시 충격을 최소화하여 볼밀 바닥 부분으로 떨어졌을 때 최대한의 충격을 주어 분쇄하고자 하는 물질이 기존 볼밀보다 분쇄 효율이 좋아진다. 그리고 안내판과 볼밀 내벽에 공간을 두어 시간이 흘러 볼에 의해 잘게 부서진 물질들이 내벽에 붙어 따라 돌게 된다. (그 공간은 볼은 지나갈 수 없다) 그렇게 되면 나중에 볼이 잘게 부서진 물질과도 계속적인 충격을 가할 수 있어 기본 볼밀보다 고운 결과물을 얻을 수 있다.
