본 고안의 구조는 제 1도의 단면도에 표시되며, 제 2도는 분리 부문의 상세한 확대도이다. 본 고안은 중앙종축(20)내부에 배출도관(21)을 형성하여 배출도관의 상부에 설치되는 원형 분리장치(22)의 하부와 연결되어져 있고, 그 외측을 컵형태의 실린더가 회전가능토록 지지하우징(23)에 의하여 지지되어 있으며, 케이싱과 냉각부가 중앙종축을 감싸고 내부에 연마용 공간부를 갖는 볼밀교반 장치에 있어서,The structure of the present invention is shown in the cross section of FIG. 1, and FIG. 2 is a detailed enlarged view of the separation section. The present invention is connected to the lower portion of the circular separating device 22 is installed on the upper portion of the discharge conduit to form the discharge conduit 21 in the central longitudinal axis 20, the outside of the cup-shaped cylinder to support the rotatable In the ball mill stirrer supported by the housing 23, the casing and the cooling portion surround the central longitudinal axis and have a polishing space therein,

환형의 최외측케이싱(40)과 환형의 내측케이싱(46)사이에 환형의 중앙분리냉각부(45)를 배치하여 놓고,Between the annular outermost casing 40 and the annular inner casing 46 is arranged an annular central separation cooling portion 45,

상기한 중앙분리냉각부(45)를 컵형태로 덮어주는 U자형의 회전실린더(32)가 배치되어지되 회전종축(100)과 원반형 브라켓트(60)를 매개로 회전가능토록 설치하였으며,The U-shaped rotating cylinder 32 covering the central separation cooling unit 45 in the form of a cup is disposed, but is installed to be rotatable through the rotational longitudinal axis 100 and the disk-shaped bracket 60.

환형플렌지(4)의 공급도관(34)과 연통되는 공급로(35)가 최외측케이싱(40)과 경계하는 제 1연마실(36)의 상부와 연결되며 분리장치(22)는 제 4연마실(37)의 상부와 연통되며 제 1연마실과 제 4연마실 사이에는 제 2연마실(38), 제 3연마실(39)이 연속 병립되어져 그들 상하단이 서로 관통되도록 구성한 볼밀교반장치이다.The supply passage 35 communicating with the supply conduit 34 of the annular flange 4 is connected to the upper portion of the first polishing chamber 36 bordering the outermost casing 40, and the separation device 22 is connected to the fourth station. A ball mill stirrer is in communication with the upper portion of the drink 37 and the second and third polishing chambers 38 and 39 are continuously connected in parallel between the first and fourth polishing chambers so that their upper and lower ends penetrate each other.

본 고안의 최외측케이싱(40)은 환형플렌지(4)에 의해 커버(5)와 일체화 되면서 일측에 공급도관(34)이 연결토록 하면서 지지하우징(23)의 하측에 고정되어 있으며, 지지하우징은 케이싱의 중앙종축(20)과 동축으로 배열되어있는 회전종축(100)을 내장토록한채 하부의 회전실린더(33)와 연결토록하여 장치전체 중앙을 관통토록하였으며, 이 축에는 교반을 위한 장치들이 연결되어져 있다.The outermost casing 40 of the present invention is fixed to the lower side of the support housing 23 while the supply conduit 34 is connected to one side while being integrated with the cover 5 by the annular flange 4. The rotating longitudinal axis 100, which is arranged coaxially with the central longitudinal axis 20 of the casing, is connected to the lower rotating cylinder 33 while being built therein so as to penetrate the entire center of the apparatus. It is done.

저면부(30)에는 냉각수 공급구(40a),(45a),(46a)가 각각의 최외측케이싱(40), 중앙분리냉각부(45), 내측케이싱(46)의 하측단에 형성되어 냉각수가 흐르도록 하였다.Cooling water supply ports 40a, 45a, and 46a are formed in the bottom surface 30 at lower ends of each of the outermost casing 40, the central separation cooling unit 45, and the inner casing 46. Was allowed to flow.

분리장치(22)는 다수의 공극이 천공된 망구조로서 배출도관(21)의 흡입력에 의하여 망을 통과하는 것만 통과토록한 것이다.Separator 22 is a network structure in which a plurality of voids are to pass only through the network by the suction force of the discharge conduit 21.

회전실린더(33)와 중앙분리냉각부(45)의 외주면 그리고 내측케이싱(46)에는 교반을 위한 교반기기(50)들이 교호로 배열되어 있다. 실린더내에 공급되는 연마입자(70)들은 원형외에도 다양한 형태가 채용가능하도록하며 그 입경이 분리장치를 통과하지않을 정도이면 가능하다.Stirring devices 50 for agitation are alternately arranged on the outer circumferential surface and the inner casing 46 of the rotary cylinder 33, the central separation cooling unit 45. The abrasive grains 70 supplied in the cylinder can be employed in various forms in addition to the circular shape, as long as the particle diameter does not pass through the separation device.

본 고안 또다른 특징은 비드흡입이 분리장치의 망체에 접촉이 없도록 ㄱ자형 흡입방지부(55)를 돌출부가 분리장치 쪽으로 배치토록 형성하여 소공(51)만을 분리장치와 제 4연마실사이에서 형성토록한 것이다.Another feature of the present invention is that the bead suction is formed so that the protrusion is disposed toward the separation device so that the bead suction does not contact the mesh of the separation device so that only the small hole 51 is formed between the separation device and the fourth grinding chamber. It is.

이 흡입방지부는 제 2도에 도시하듯이 중앙의 분리장치(22)를 향하여 원반형 브라켓트(60)와 체결되는 회전실린더(33)의 상측에 형성된 리사이클 유도로(56)의 입구부에 일단이 접한채 타단은 중앙의 분리장치(22)를 향하여 방사상 배치되어져 있어서 회전시 비드의 원심력으로 비드입자가 제 1연마실(36)로 리사이클되도록 하는 것이다.As shown in FIG. 2, the suction preventing part is in contact with the inlet of the recycling induction path 56 formed on the upper side of the rotation cylinder 33 which is engaged with the disk-shaped bracket 60 toward the central separator 22. As shown in FIG. The other end is disposed radially toward the center separator 22 so that the bead particles are recycled to the first polishing chamber 36 by the centrifugal force of the beads during rotation.

이상의 본 고안은 피분쇄물이 종래의 장치와 달리 연마실이 4개로 배가되어 마찰거리가 크게 증가되므로 결국 마찰시간도 배가되어 분쇄효과가 배가되는 것이다. 즉 단위시간당 마찰거리가 배가되어 원가절감 및 더욱 미분된 분체의 획득이 가능한 것이다.The present invention is that the grinding object is doubled to four grinding chambers, unlike the conventional apparatus, so that the friction distance is greatly increased, so that the friction time is also doubled and the grinding effect is doubled. That is, the friction distance per unit time is doubled, so that cost reduction and more fine powder can be obtained.

또한 분리장치에 ㄱ자형 흡입방지부의 설치로 비드입자의 상승시 돌출부에 걸리에 되어 망체를 타격하는일이 없어 수명연장과 분리 효율 상승을 효과를 얻을수 있다.In addition, the L-shaped suction prevention part is installed in the separation device, so that the bead is caught on the projection when the bead particles are raised, so that the net body is not hit and the life extension and separation efficiency can be increased.

특히 비드입자가 자신의 무게가 큰 관계로 원심력에 비해 제 1연마실로 계속 리사이클되므로 분리장치에 대한 타격을 없애줌은 물론 안정된 동작이 연속적으로 가능한 것이다.Particularly, because the beads have a large weight, the particles are continuously recycled to the first polishing chamber compared to the centrifugal force, thereby eliminating the impact on the separation device, as well as enabling stable operation continuously.
