Description

선별스크린에서의 광석분산장치{APPARATUS FOR DISPARTING ORE IN SELECTION SCREEN}Ore Dispersion in Separation Screen {APPARATUS FOR DISPARTING ORE IN SELECTION SCREEN}

본 발명은 선별스크린에서의 광석분산장치에 관한 것으로, 보다 상세하게는 광석파쇄공정을 거친 파쇄광이 컨베어벨트에 의해 선별스크린의 중앙부분에 집중낙하되는 것을 방지하기 위하여 파쇄광을 스크린의 상부에서 분산시키는 선별스크린에서의 광석분산장치에 관한 것이다.The present invention relates to an ore dispersing apparatus in a sorting screen, and more particularly, in order to prevent the crushed light that has undergone the ore crushing process from being concentrated on the central portion of the sorting screen by a conveyor belt. The present invention relates to an ore dispersing apparatus in a sorting screen for dispersing.

일반적으로 파쇄광 선별공정은 파쇄광을 정립광(8∼30㎜)과 사하분(8㎜이하)으로 분리하는 공정이다.In general, the crushed light sorting step is a process of separating the crushed light into standing light (8 to 30 mm) and quadrant (8 mm or less).

도 1은 종래기술에 따른 파쇄광 선별장치의 사시도 및 단면도이다.1 is a perspective view and a cross-sectional view of a crushed light sorting device according to the prior art.

이러한 파쇄광 선별장치는 도 1에 도시된 바와 같이, 광석 파쇄기에서 파쇄된 광석을 이송시키는 컨베어벨트(4)와 스크린본체(1) 및 상,하부 스크린망(2)과 상기 스크린망(2)의 장력을 유지시켜주기 위한 지지바(7)로 구성된다.As shown in FIG. 1, the crushed light sorting device includes a conveyor belt 4, a screen main body 1, upper and lower screen nets 2, and the screen net 2 for transferring the crushed ore in the ore crusher. It consists of a support bar (7) for maintaining the tension of.

이와같은 파쇄광 선별장치에서는 다양한 입도의 파쇄광(3)이 컨베어벨트(4)에 의해 이송되어 온 후 입도선별작업을 위하여 스크린망(2)에 낙하되는데, 컨베어벨트(4)의 폭은 1m 임에 비하여 스크린망(2)의 폭은 3m 이상이므로 파쇄광이 상기 스크린망(2)의 좌우측에 분산되지 않고 스크린망(2)의 중앙부에만 낙하되어 스크린망(2)의 부분적인 집중마모에 의한 파손으로 파쇄광의 입도선별작업이 제대로 이루어지지않는다.In the crushed light sorting device as described above, the crushed light 3 having various particle sizes is transported by the conveyor belt 4 and then dropped on the screen net 2 for the particle size sorting operation. The width of the conveyor belt 4 is 1 m. On the contrary, since the screen net 2 has a width of 3 m or more, the crushed light is not dispersed to the left and right sides of the screen net 2, but falls only to the central portion of the screen net 2, thereby causing partial intensive wear of the screen net 2. Due to breakage, the particle size selection of crushed light is not done properly.

도 2에 파쇄광의 중앙부 집중낙하에 의해 스크린망이 파손된 상태를 도시하였다.2 shows a state where the screen net is broken due to the central falling of the crushed light.

이와같은 문제점을 해결하기 위하여 종래에는 실용신안 공개번호 96-605호에 나타난 바와 같이 스크린망의 선단부에 파쇄광 분산판을 장착하여 사용하여 왔다.In order to solve such a problem, conventionally, as shown in Utility Model Publication No. 96-605, a crushed light distribution plate has been used at the front end of the screen network.

그러나, 상기 스크린망의 선단부에 설치되는 분산판은 파쇄광의 낙하에 의한 충격을 완화시킬수 없고, 파쇄광(3)이 적게 이송되어 올때는 광석의 분산이 가능하나 파쇄기로부터 많은 양의 광석이 한꺼번에 스크린망의 선단부에 낙하될때는 분산작업이 효율적으로 이루어지지 않아 스크린망의 파손에 의해 파쇄광의 입도 선별불량 및 스크린망의 잦은 교환으로 설비가동율이 저하되는 문제점이 있다.However, the dispersion plate installed at the front end of the screen net cannot mitigate the impact of falling of the crushed light, and when the crushed light 3 is transported less, the ore can be dispersed but a large amount of ore from the crusher is screened at once. When falling to the front end of the distribution operation is not made efficiently, there is a problem that the operation rate of the facility is reduced by the poor screening of the crushed light due to breakage of the screen net and frequent replacement of the screen net.

상기와 같은 문제점을 해결하기 위하여, 본 발명은 별도로 집광슈트를 설치하고 이와 연결된 분산슈트에 의해 파쇄광을 분산시켜 스크린망에 낙하시킴으로써 스크린망의 부분적이 집중마모를 방지하여 스크린망의 조기파손을 방지할 수 있는선별스크린에서의 광석분산장치를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention is to install the light collecting chute separately and to disperse the crushed light by the dispersion chute connected to the screen net to prevent partial damage of the screen net to prevent early damage of the screen net It is an object of the present invention to provide an ore dispersing device in a screen that can be prevented.
