怎样使用选金船中的鼓动溜槽--统一重工告诉您

      链斗式挖沙选金船是一种水上采金设备,该设备的处理量大,对细粒金的回收效果显著,特别是对-01037mm粒级回收效果明显,在原有设备基本上能保证+01037mm粒级的回收。链斗式挖沙选金船的选别指标很好,沙金的分级比较高。而且链斗式挖沙选金船结构简单,便于操作和维护,功耗低。青州统一重工生产的链斗式挖沙选金船更是出口到南非、智利、马达加斯加等国家。
      由于黄金的化学性质稳定,一般不与其他物质反应,所以它以游离态存在于沙石中。在自然的风化作用下,岩石破碎,最后形成沙子和土,而颗粒状的金沙就埋藏在其中。在流水的冲刷、搬运下,泥沙、金子的颗粒和水一起移动,它们移动的速度和状态不同,所以在河床的某区域可以形成金沙富积的地带,人们在这里使用链斗式挖沙选金船,将河沙挖到淘金斗里,再抽河水冲斗里的沙子,大量的沙子就被水带走,在斗里留下的就是金灿灿的金子。
      链斗式挖沙选金船挖掘的物料在经过鼓动溜槽时在纵向水流作用下,矿浆流经具有一定高度和距离并通过精心设计的格条,可以产生旋窝和脉动水流,漩涡的回转运动不断地将比重大的金粒及其他重矿物转送到底层。在那里水流的紊动作用减弱,容积浓度达到很大。因此,轻矿物的大颗粒很难进入,只有细的重矿物颗粒通过间隙进入底层,形成重沙层。由于溜槽精矿不是连续排出,随着工作时间的增长,溜格间的沉积物越来越致密从而影响了矿物的进一步分层,是选别效果逐渐变坏。鼓动溜槽使底板产生鼓动,实质上每个溜格间的橡胶板相似于跳汰机的隔膜,有效的解决了床层板结问题。

      链斗式挖沙选金船中跳汰机的选矿是在上升水流作用下使床层松散,在下降水流时产生吸入作用,矿物颗粒按比重分层,重矿物钻隙到底层面被回收。而鼓动溜槽则没有补充上升水流的作用,也不加入人共床层,而是通过很多长条形隔膜直接作用于沉积矿层和矿浆,隔膜上升阶段使矿物颗粒上升,沉积层出于松散状态,隔膜下降时也产生一定的吸入作用,矿物颗粒按比重分层。自然金比重比脉石矿物大数倍,因此很快钻隙到底层而被回收。由于受格条的阻挡及自然床层的保护,被回收到底层的自然金不会被矿浆流再次带走。

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.
