CGZL  40型组合式擦洗圆筒筛——振动溜槽洗选机组是在我厂多年生产固定溜槽系列产品基础上研制的。几年来，我院、厂工程技术人员到国内外各大金矿认真考察调研，虚心听取用户意见和要求，结合地质金矿不同的特征，矿砂粘性大小，针对处理砂金原生矿和大量的尾砂，回收微粒和毛毛金，进一步提高采金回收率进行设计制造。经过国内外各大用户的使有证明该机组矿砂处理量大，洗净度高，采金回收率高，不但能回收粒状和片状金，还可以收回微粒和毛毛金，是目前国内外比较先进、适用性强的砂金选矿设备，该机组具有以下特点：

1、该机组结构设计合理、强度高，可拆性强，便于运输和搬迁；

2、矿砂处理量大；

3、矿砂洗净度高，很适用在粘性大的砂金矿区进行洗选作业；

4、采金回收率高。该机组溜槽部分是振动的，筛下的矿砂料在溜槽内始终处于起浮状态，使砂金有更多的机会沉积在毛毡的空隙中，使之既能回收粒状和片状金，还能回收    0.02mm以下的微粒金毛毛金。所以采金回收率高，入选回收率达到95%以上；

5、该机组适应性强，可在任何地质结构、任何金矿区作业，无论对原生矿或尾砂矿都具有较好的选矿效果，也可在少水和缺水金矿区生产；

6、用水量少，耗能低，节省劳动力，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.
