怎樣使用選金船中的鼓動(dòng)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(shè)備，該設(shè)備的處理量大，對(duì)細(xì)粒金的回收效果顯著，特別是對(duì)-01037mm粒級(jí)回收效果明顯，在原有設(shè)備基本上能保證+01037mm粒級(jí)的回收。鏈斗式挖沙選金船的選別指標(biāo)很好，沙金的分級(jí)比較高。而且鏈斗式挖沙選金船結(jié)構(gòu)簡(jiǎn)單，便于操作和維護(hù)，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(dá)加斯加等國(guó)家。
      由于黃金的化學(xué)性質(zhì)穩(wěn)定，一般不與其他物質(zhì)反應(yīng)，所以它以游離態(tài)存在于沙石中。在自然的風(fēng)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(yùn)下，泥沙、金子的顆粒和水一起移動(dòng)，它們移動(dòng)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?cè)谶@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(guò)鼓動(dòng)溜槽時(shí)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(guò)精心設(shè)計(jì)的格條，可以產(chǎn)生旋窩和脈動(dòng)水流，漩渦的回轉(zhuǎn)運(yùn)動(dòng)不斷地將比重大的金粒及其他重礦物轉(zhuǎn)送到底層。在那里水流的紊動(dòng)作用減弱，容積濃度達(dá)到很大。因此，輕礦物的大顆粒很難進(jìn)入，只有細(xì)的重礦物顆粒通過(guò)間隙進(jìn)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(shí)間的增長(zhǎng)，溜格間的沉積物越來(lái)越致密從而影響了礦物的進(jìn)一步分層，是選別效果逐漸變壞。鼓動(dòng)溜槽使底板產(chǎn)生鼓動(dòng)，實(shí)質(zhì)上每個(gè)溜格間的橡膠板相似于跳汰機(jī)的隔膜，有效的解決了床層板結(jié)問(wèn)題。

       鏈斗式挖沙選金船中跳汰機(jī)的選礦是在上升水流作用下使床層松散，在下降水流時(shí)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(dòng)溜槽則沒(méi)有補(bǔ)充上升水流的作用，也不加入人共床層，而是通過(guò)很多長(zhǎng)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(shí)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(hù)，被回收到底層的自然金不會(huì)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.
