怎樣使用選金船中的鼓動溜槽--統(tǒng)一重工告訴您

      鏈斗式挖沙選金船是一種水上采金設備，該設備的處理量大，對細粒金的回收效果顯著，特別是對-01037mm粒級回收效果明顯，在原有設備基本上能保證+01037mm粒級的回收。鏈斗式挖沙選金船的選別指標很好，沙金的分級比較高。而且鏈斗式挖沙選金船結構簡單，便于操作和維護，功耗低。青州統(tǒng)一重工生產(chǎn)的鏈斗式挖沙選金船更是出口到南非、智利、馬達加斯加等國家。
      由于黃金的化學性質穩(wěn)定，一般不與其他物質反應，所以它以游離態(tài)存在于沙石中。在自然的風化作用下，巖石破碎，最后形成沙子和土，而顆粒狀的金沙就埋藏在其中。在流水的沖刷、搬運下，泥沙、金子的顆粒和水一起移動，它們移動的速度和狀態(tài)不同，所以在河床的某區(qū)域可以形成金沙富積的地帶，人們在這里使用鏈斗式挖沙選金船，將河沙挖到淘金斗里，再抽河水沖斗里的沙子，大量的沙子就被水帶走，在斗里留下的就是金燦燦的金子。
      鏈斗式挖沙選金船挖掘的物料在經(jīng)過鼓動溜槽時在縱向水流作用下，礦漿流經(jīng)具有一定高度和距離并通過精心設計的格條，可以產(chǎn)生旋窩和脈動水流，漩渦的回轉運動不斷地將比重大的金粒及其他重礦物轉送到底層。在那里水流的紊動作用減弱，容積濃度達到很大。因此，輕礦物的大顆粒很難進入，只有細的重礦物顆粒通過間隙進入底層，形成重沙層。由于溜槽精礦不是連續(xù)排出，隨著工作時間的增長，溜格間的沉積物越來越致密從而影響了礦物的進一步分層，是選別效果逐漸變壞。鼓動溜槽使底板產(chǎn)生鼓動，實質上每個溜格間的橡膠板相似于跳汰機的隔膜，有效的解決了床層板結問題。

       鏈斗式挖沙選金船中跳汰機的選礦是在上升水流作用下使床層松散，在下降水流時產(chǎn)生吸入作用，礦物顆粒按比重分層，重礦物鉆隙到底層面被回收。而鼓動溜槽則沒有補充上升水流的作用，也不加入人共床層，而是通過很多長條形隔膜直接作用于沉積礦層和礦漿，隔膜上升階段使礦物顆粒上升，沉積層出于松散狀態(tài)，隔膜下降時也產(chǎn)生一定的吸入作用，礦物顆粒按比重分層。自然金比重比脈石礦物大數(shù)倍，因此很快鉆隙到底層而被回收。由于受格條的阻擋及自然床層的保護，被回收到底層的自然金不會被礦漿流再次帶走。

Chain bucket digging sand Gold ship is a kind of water mining equipment, the equipment of large amount of processing, the recovery of fine gold is remarkable, especially for the -01037mm grain grade recovery effect, in the original equipment basically can guarantee the +01037mm grain grade recycling. The selection index of the chain bucket dredging gold ship is good, and the grading of alluvial sediment is higher. And the chain bucket digging sand selection of gold ship structure is simple, easy to operate and maintain, low power consumption. The chain bucket digging sand selection of the unified heavy industry production in Qingzhou is exported to South Africa, Chile, Madagascar and other countries.

Because the chemical properties of gold are stable and generally do not react with other substances, it exists in the sandstone in the Free State. In natural weathering, rocks are broken and sand and soil are formed, and granular sands are buried therein. In the scour and handling of the flowing water, the particles of silt and gold are moved along with the waters, and they move at different speeds and states, so the sands rich zone can be formed in a region of the riverbed. Here people use the chain bucket dig sand to choose the gold boat, river sand dug into the gold bucket, and then pumping the river in the bucket of sand, a lot of sand is taken away by water, in the bucket is the golden gold left.
Chain bucket Digging sand selection of gold ship the material under the action of the longitudinal flow in the agitation chute, the pulp flows through a certain height and distance and through elaborate design bars, can produce the spin and pulsating water flow, the vortex movement will continue to be compared to the significant gold particles and other heavy minerals to the bottom. There is a weakening of the turbulent effect of the flow and the volume concentration is very large. Therefore, the large particles of light minerals are difficult to enter, and only the fine heavy mineral particles enter the bottom layer through the clearance to form a heavy sand. Because the chute concentrate is not continuously discharged, as the working time grows, the sediment between the chute becomes more dense and thus affects the further stratification of minerals, and the effect of the separation is gradually deteriorated. Stirring the chute to make the backplane stirring, essentially each chute is similar to the rubber plate between the separator diaphragm, effectively solved the bed hardening problem.
Chain bucket Digging sand selection of the jig in the gold ship in the rise of water under the action of the bed loose, in the descent of the flow of inhalation effect, mineral particles by the gravity of layered, heavy mineral drilling clearance at the end of the level is recycled. And the agitation chute does not complement the rise of water. Do not join the human bed, but through a lot of long strip diaphragm directly effect on the sedimentary seam and pulp, the diaphragm rising stage of mineral particles, the sedimentary layer out of loose state, the diaphragm drops also produced a certain inhalation effect, mineral particles by the proportion of stratification. The proportion of natural gold is larger than the gangue minerals, so it is recycled quickly to the bottom. Because of the barrier of the lattice bar and the protection of the natural beds, the natural gold recovered to the bottom is not taken away by the slurry flow.
