CGZL  40型組合式擦洗圓筒篩——振動溜槽洗選機組是在我廠多年生產固定溜槽系列產品基礎上研制的。幾年來，我院、廠工程技術人員到國內外各大金礦認真考察調研，虛心聽取用戶意見和要求，結合地質金礦不同的特征，礦砂粘性大小，針對處理砂金原生礦和大量的尾砂，回收微粒和毛毛金，進一步提高采金回收率進行設計制造。經過國內外各大用戶的使有證明該機組礦砂處理量大，洗凈度高，采金回收率高，不但能回收粒狀和片狀金，還可以收回微粒和毛毛金，是目前國內外比較先進、適用性強的砂金選礦設備，該機組具有以下特點：

1、該機組結構設計合理、強度高，可拆性強，便于運輸和搬遷；

2、礦砂處理量大；

3、礦砂洗凈度高，很適用在粘性大的砂金礦區進行洗選作業；

4、采金回收率高。該機組溜槽部分是振動的，篩下的礦砂料在溜槽內始終處于起浮狀態，使砂金有更多的機會沉積在毛氈的空隙中，使之既能回收粒狀和片狀金，還能回收    0.02mm以下的微粒金毛毛金。所以采金回收率高，入選回收率達到95%以上；

5、該機組適應性強，可在任何地質結構、任何金礦區作業，無論對原生礦或尾砂礦都具有較好的選礦效果，也可在少水和缺水金礦區生產；

6、用水量少，耗能低，節省勞動力，降低投入成本。

CGZL40Combinational Scrubbing Drum Screen-Vibrating Sluice  Washing Separation Machine unit is developed based on our factory many years’  production of stationary sluice series of products. In the recent years,  technicians from our Institute and factory have made visits to the major gold  mines at home and abroad for study and investigation. The unit is designed and  manufactured after soliciting opinions and demands from users, in line with the  properties of geological gold ores and viscosity of ore sand and in response to  treatment of placer gold crude ore and massive sand tailings, recovery of fine  particles and slight gold and further improvement of gold recovery rate. The  applications by the major users at home and abroad showed that the unit could  handle great amount of ore sand，with high washing cleanliness and gold recovery rate. The unit can  recover not only granular gold and platy gold but also fine grained cold and  slight gold and is considered as relatively advanced and strongly adaptable  placer gold separation equipment with its features described as follows:

1. Rational structure in design with high strength and  convenient dismounting, easy for transport and transfer.

2. Large mineral sand handling capacity up to ≤    100m³/h

3. High mineral sand washing cleanliness, suitable for  washing separation of placer gold with great viscosity.

4. High recovery rate of gold mining; The unit has a  vibrating sluice with the undersized mineral sand materials in sluice being  always kept floating, which allows placer gold to have more chance to settle in  cracks of felt so as to recover granular and platy gold as well as slight gold  of fine grain of    0.02mm and  below. As a result, the recovery rate of gold mining is expected to be very high  and recovery rate of feed will be up to 95 % and above.

5. The unit with strong adaptability will have good mineral  processing results for either primary ore or sand tailings in whatever  geological structure and in operation at any gold mine, and also can be applied  in production in the gold mines with insufficiency and shortage of water  supply.

6. Less water consumption, lower energy consumption, fewer  labor requirement and less investments cost.
