一、概述

CGLC60A型溜槽是在我廠引進的美國、俄羅斯溜槽和國內(nèi)龍江I型溜槽的基礎(chǔ)上，吸收其先進結(jié)構(gòu)的優(yōu)點進行設(shè)計制造的，并經(jīng)過多次生產(chǎn)實驗，多次改進后生產(chǎn)定型的。它具備以下各項優(yōu)點：

1、金礦砂處理量大，每小時可洗選礦砂60    -    80m³/h，砂石≤    10mm時可達    150  m³/h。

2、結(jié)構(gòu)合理，強度高，可拆裝性強，便于運輸搬遷。

3、采金回收率高，回收率可達到85-90%，不但能回收粒狀金、片狀金，還可回收微粒金。

4、適應(yīng)性很強，可在任何條件的礦體內(nèi)選礦。

二、溜槽的主要技術(shù)參數(shù)

三、溜槽主要結(jié)構(gòu)及作用

1、上料臺：是承裝礦砂料的部位，也是充分造漿的部位。

2、篩分裝置：篩分裝置由篩板和大小分流箱組成。

3、溜槽：溜槽分主溜槽、副溜槽。主溜槽在中間，副溜槽分置兩側(cè)。是采金選礦的主要部位。

4、溜格：溜格分主溜格、副溜格。主溜槽內(nèi)放9個主溜格，副溜槽內(nèi)（每側(cè)）放11個副溜格。

5、底坐：由4根地梁和11根橫梁組成，上述三大部件按順序組裝在底座上，組成一臺完整溜槽。

6、主噴水管：是采金選礦的水源裝置，它由12寸混流泵供水，裝在斜篩板上方。

7、副噴水管：補充主噴水管水量，擴大噴水范圍，在主噴水管尾部接6寸膠管與副噴水接通，裝在方篩板上方。

8、塑料毛氈：鋪在主、副溜槽底部，是珍藏砂金的主要部位。

9、電氣裝置：可用柴油機帶動，也可用發(fā)電機組，有電路地區(qū)，也可用電動機驅(qū)動。

10、附屬設(shè)備：砂金精選機、金砂箱。

四、安裝與調(diào)試

安裝位置選定后，用推土機將剝離的非礦砂推成角度為10º-12º，長    14m，寬    5m的坡形基座，上面鋪上6-8根枕木，操平，按先后順序?qū)⒘锊劢M裝在座機上，各連接部用螺栓連接，用力把緊。根據(jù)砂金顆粒大小和形狀，確定溜槽安裝角度。當(dāng)粒狀金或以大、中粒為主時，宜坡度稍大，當(dāng)砂金顆粒小，以片狀、微粒金為主時，宜坡度稍??；以保證回收率。溜槽角度確定后，調(diào)好定位。

按選定位置安裝水泵，并用膠管連接成回路。

安裝好動力線和電氣操縱裝置。

一切準備就緒后，接通電源和水泵進行試溜，試溜成功，就可投入生產(chǎn)。每八小時清溜一次，在清溜前，先停止供料，繼續(xù)供水，清洗5-10分鐘后停水。取出主、副溜格將毛氈上的浮砂收起放入金砂箱，然后將毛氈卷起放入金砂箱抖洗，毛氈洗凈后放回溜槽內(nèi)，繼續(xù)生產(chǎn)。將金砂箱內(nèi)的金砂，用鍬放入精選機上進行精選，然后經(jīng)過人工精淘產(chǎn)出砂金。

五、溜槽操作注意事項

1、上料臺、主、副溜槽各篩板為鋼板焊接而成，在供料、推尾砂和搬遷運輸中，嚴防碰撞以防嚴重變形，造成停產(chǎn)。

2、在洗選中，在額定容量內(nèi)，主、副槽內(nèi)必須有足夠水，如水量不均或不夠，應(yīng)及時調(diào)整水泵，溜槽內(nèi)的礦漿液固比一般為10-12：1，礦漿流速為1.4    -    1.6米/秒,安裝溜槽時,橫向應(yīng)保持水平.

3、溜槽篩板用于礦砂篩分選礦，當(dāng)篩孔嚴重堵塞時，應(yīng)在清溜時及時清除。

4、在洗選中，清溜時間根據(jù)實際情況定。當(dāng)金粒較大時，宜8-10小時清溜一次，當(dāng)金粒較小或片狀時宜6- 8小時清溜一次。

5、溜槽搬遷時，距離遠應(yīng)解體分組搬遷，在新基座上組裝，其安裝順序和要求同前。連接螺栓必順緊固。距離近時，整體搬遷，必順拉牽引杠，牽引杠穿在地梁兩端各孔內(nèi)，不準牽引其它部位。

1．General

CGLC60A Combined Placer Gold Separation  Chute is designed and manufactured by assimilating advantages of the advanced  structure on the basis of American chute imported by our factory and Longjiang  1 Model Chute in      China.  It also has undergone many production tests and improvements with its  advantages as follows:

A．Large  capacity of handling placer gold at a washing capacity of 60    -80m³/h.

B．Rational  structure, high strength, removable and easy to be transported and transferred.

C．High  recovery in gold mining at a rate of 75-80%, recovering not only granular gold  and platelet gold but particulate gold.

D．Strong  adaptability and applicable for beneficiation of ore deposits at any  conditions.

2．Technical Data Placer Gold Separation Sluice

3．Main Structure and Function of Chute

A．Feeding  platform - section of carrying gold placer materials and place where pulp is  fully produced.

B．Screening  device – composed of screen plate and separation box.

C．Chute –  including primary chute and secondary chute with the primary chute put in place  in middle and the secondary chute on both sides; major part of gold mining and  separation.

D．Chute –  including primary chute and secondary chute with the former housing 9 lattices  and the latter containing 11 lattices on every side.

E．Base – made  up of 4 ground beams and 11 cross beams, which are mounted on the base in  order, forming a complete chute.

F．Main water  spraying pipe – water source device for gold mining and separation, composed of    12 in flow blending pump for  water supply which is mounted above inclined screen plate.

G．Secondary  water spraying pipe – replenishing water volume for the primary water spraying  pipe and expanding area of water spraying, connecting with the primary water  spray by linking    6 in rubber  pipe at its end; mounted above the square screen plate.

H．Plastic  felt – covered at the bottoms of the primary and secondary chutes, a main area  for storing placer gold.

I．Electrical  device – driven by either diesel engine or electrical generator; If electric  circuit is available in the area, electrical motor can be used for operation.

J．Auxiliary  equipment: placer gold separator and gold placer box.

4．Installation and commissioning

After the position of installation is  selected, stripped waste rock will be pushed by bulldozer to form slope  foundation with dip angle 100~120, 14 meters in length and 5 meters in width.  6~8 pieces of timber sleeper are put on the foundation and then leveled. The  chute will be assembled on the foundation according to sequences. Each  connecting points will be connected with bolts. All bolts must be tightened.  The installation angle of chute will be determined according to the size and  shape of placer gold particles. The slope of chute should be slightly large,  when platelet gold or large and medium particles of placer gold are dominant.  The slope of chute should be slightly small, when the platelet and particulate  gold and small particles of placer gold are dominant to ensure recovery. After  the angle of the chute is determined, the position of the chute will be  adjusted.

Water pump should be installed on the  position selected, and connected to form return circuit with rubber hose.

Power line and electric operating equipment  should be installed properly.

When everything is ready, power supply and  water pump will be connected to conduct chute beneficiation experiment. If the  experiment is successful, the chute can be used in production. The chute should  be cleaned every 8 hours. Before cleaning, feeding should be stopped, and water  should be supplied continuously. After cleaning 5~10 minutes, the supply of  water should be stopped. Main and auxiliary chute lattices are taken out, and  floating sands on the hair felt are collected to the gold sand tank before  rolling up the hair felt and putting it into the gold tank for vibrating and  washing . After being cleaned, the hair felt is put back into the chute, and is  used to produce gold placer again. The gold sand in the gold placer tank will  be sent with spade to cleaning machine to product cleaning. Then gold placer  will be produced via manual fine elutriation.

5．Important for chute operation

A．The plates  of feeding platform, primary chute and secondary chute are welded with steel  plate and should be protected from collision to avoid deformation during  material supply, feeding tailing and transport.

B．During  washing, adequacy water in primary chute and secondary chute should be ensured  at rated capacity and adjustment of pump should be done timely in case of shortage  of water supply. Generally solid-liquid ratio of slurry in the chute is  10~12:1, flow velocity is 1.4~    1.6 m/s.  Lateral of chute should be kept level.

C．Screen  plate of the chute is used for screening placer gold. When screen holes are  blocked, it should be cleaned timely.

D．In washing,  cleaning time of chute is determined according to actual situation. If gold  grain is bigger, a cleaning chute per 8~10 h., if gold grain is small or platelet  gold, a cleaning chute per 6~8 h.

E．In moving  chute for long distance, disassembly moving should be done, assembly on new  base should be according to previous installation sequence, jointing bolt must  be tightened. If chute is moved in whole unit, drawbar must be used, passing  hole in two ends of ground beam, other part of chute can be not drawn.
