淘金船有哪幾大系統組成，原理是什么？
隨著近幾年金價的飆升，淘金熱再度興起，淘金船等淘金設備的熱銷，促進了技術的進步，淘金凈選率從原先的30%左右，一下提高到90%以上，極大的增加了投入產出比。先進的設備、極高的效益，又更進一步刺激了淘金熱，成為投資的熱門。淘金設備形式眾多，各有千秋，一般來說，在水流的沖刷作用下，河流中河沙金的含量比旱地上河沙中的含量高，現將復雜的淘金設備----淘金船的原理和操作規程簡介如下： 設備組成：
顧名思義，淘金船就是把淘金系統移動到了船上，增加了河沙挖掘系統，在水面上組成了移動的綜合河沙選礦廠。本淘金設備由浮體、挖掘系統、篩分系統、淘金系統、尾砂排出系統、動力系統、供水系統等組成。 設備淘金船原理：
首先，挖掘系統將河沙從水下的河床上挖出水面，然后進入篩分系統進行篩分，大于10mm的石子進入尾礦槽，由尾砂排出系統排到遠離淘金船的地方，以保證淘金船不被淤積，能連續工作。小于10mm的物料從導流槽進入淘金系統進行金沙分離，依據沙和金比重的差別，比重大的金沉降于礦漿底部，比重小的沙子等物料浮于礦漿上層隨水流排到尾砂排出系統。
1.浮體。浮體一般做成分體形式，兩個邊浮箱，中間間隔一定距離，既增加了淘金船的穩定性，又便于設備的拆裝運輸。浮體的長度是根據挖沙的深度設計的，挖沙深度越大，浮體越長。浮體的寬度設計是根據設備的工作重量，一般來說，工作量越大，浮體越寬。
2.挖掘系統。淘金船的挖掘系統有挖沙斗和鏈條組成的鏈斗挖掘式、射吸管和抽砂泵組成的射吸式、絞刀和抽砂泵組成的絞吸式等多種挖掘形式，根據多年的安裝經驗，由于沙金的比重很大，鏈斗挖掘形式優于射吸式和絞吸式。
3.篩分系統。篩分系統也有多種形式，原礦中石子比較多的，用滾筒篩篩分效果好，石子比較少的，可以用平篩，如果原礦中石子的粒度小于10mm，可以將篩分系統省掉。
4.淘金系統。淘金系統的形式有固定淘金氈溜槽、鼓動式淘金溜槽、自動洗選機加淘金離心機、螺旋溜槽、搖床、淘金汞板等，目前應用多的是鼓動式淘金溜槽和自動洗選機加淘金水套離心機形式，這兩種形式結構簡單，體積小，便于移動，處理量大，自動化程度高、富集比高（1000:1），凈選率達到了90%以上，是目前淘金船和旱地淘金設備的。
5尾砂排出系統：尾砂排出系統有抽砂泵式、溜槽式、傳送帶式等，一般常用的形式是溜槽式，無動力，維修方便，造價省.
6.動力系統。由于淘金船的自動化程度要求高，電動機成為淘金船的動力，沒有電力架設的河道，可以配柴油發電機組.
7.供水系統。淘金作業礦漿的佳濃度在30%左右，供水系統需要持續提供兩倍于處理量的工作用水.
淘金船上還有好多的設備協同完成從挖掘到選金到尾砂排出的系統工作，比如提升系統，用于挖沙大臂的起降、絞錨系統，用于淘金船作業的固定、照明系統，用于夜間作業的照明、螺旋槳，提供淘金船的水上自航等，
Gold rush principle:
First of all, the river sand mining system from the water bed out of water, and then enter the screening system for screening, more than 10mm stones into tailing tank, from tailings discharged from the system to far away from the gold rush ship, to ensure that the gold rush ship was not silt, can work continuously. Less than 10mm material from the guiding groove into the system of separation of gold and gold on the basis of Jinsha, sand proportion difference, than the major gold settlement on the pulp bottom, a small proportion of sand and other materials floating in the upper layer with water discharged into the tailings slurry discharge system.
1. floating body. The floating body is usually made up of a component body, two side floating boxes, and a certain distance between the two sides, which not only increases the stability of the gold rush vessel, but also facilitates the disassembly and transportation of the equipment. The floating body length is according to the design depth of dredging, dredging depth increases, the longer the floating body. The width of the floating body is designed according to the working weight of the equipment. Generally speaking, the larger the work load is, the wider the floating body is.
2. mining system. The system is composed of gold mining ship dredging bucket and chain bucket type, shoot Straw and various mining sand pump is composed of injection suction, cutter and sand pump is composed of a cutter suction mining form, according to the installation experience for many years, due to the large proportion of alluvial gold mining form, chain bucket is superior to shoot suction and suction cutter.
3. screening system. The screening system also has a variety of forms, more stone ore, with a roller sieving effect is good, the stones less, can use the flat screen, if the size of ore stones less than 10mm, can be saved and screening system.
4. gold panning system. The system is in the form of gold gold felt fixed chute, chute, agitation type automatic washing machine with gold centrifuge, spiral chute, shaker, mercury gold plate, is currently the most widely used agitation type chute and automatic washing machine and Gold Jacket centrifuge, the two forms of simple structure, small volume, easy to move. Large capacity, high degree of automation, enrichment ratio (1000:1), the net rate reached more than 90%, is currently the gold mining ship and dry equipment preferred.
5 tailings discharge system: tailings discharge system with sand pump, the chute type, belt type, commonly used form is no power, the chute type, convenient maintenance and cost saving.
6. power system. Due to the high degree of automation of the gold rush ship, the motor has become the preferred power of gold rush boats, no power set up the river, can be equipped with diesel generator sets
7. water supply system. The best concentration of gold ore pulp is about 30%, and the water supply system needs to provide two times the amount of working water continuously
There are a lot of gold on board equipment together to complete from the mining system to choose gold tailings to discharge, such as lifting system for landing, ground anchor system of dredging arm, used for fixing and lighting system of Pan boat operations, used for lighting, propeller work at night, for the gold rush ship water from air etc.,
