选金方法基本上分为两大类,一类是化学方法，他是根据金能与其他物质相结合或化合的特性而发展起来的方法，包括混汞法，浮选法和氰化法。化学方法选金有一定的优点，但环境污染也相当严重。第二类是物理方法，利用重力原理将进金颗粒与比重较轻的其他物质分离，如采用跳汰、摇床、溜槽、圆锥选金机等设备进行选金。振动离心选金机是属于重力选金的新型设备，从俄罗斯引进的世界先进选金技术。
Basically, gold concentration technique is classified into chemical method and physical method. The former that is further divided into amalgamation, floatation and cyanidation was developed based on the property of gold by which the gold can combines with other substances. Chemical process shows certain advantages while resulting in rather serious environment pollution. With respect to physical process, the Law of Gravity is adopted to separate gold grains from other lighter substances. This technique is used for gold concentration with jigging machine, table concentrator, glide chute and conical concentrator. Vibrating centrifugal concentrator is a new type of machine using the Law of Gravity, a globally advanced concentration technique introduced from Russia.
在选金过程中，振动离心选金机中的选金斗高速旋转，浆液进入选金斗，浆液中的颗粒受到旋转产生的径向向外的离心力作用，又不时的受到径向向内的振动力作用，不同比重的颗粒在两种力的作用下分离开，金颗粒被集中在选金斗内，而其他比重轻的颗粒被水夹带排除选金斗外。
During the concentration of gold, the concentration bin rotates at a high speed. As a result, when the pulp gets into the bin, the particles therein will be under the effect of radial outward centrifugal force due to the rotation and the effect of radial inward vibration from time to time. The particles with different specific gravities are separated under the joint action of the two forces. As a result, gold grains will concentrate in gold bin, and the particles with smaller specific gravity will be entrained in water and thus be discharged from the gold bin.
新型无污染高效振动离心选金机适用于选取单体金和比重大的大颗粒包裹金，对难处理金矿中15微米以上的微细单体金的回收率高于其他进口设备至少百分之十，岩金矿石中单体金居多，因此新型无污染高效振动离心选金机适用于大多数岩金矿和沙金矿的选金。特别是难处理金矿的****设备。对浮选和氰化后的尾矿的回收也有很高的经济价值。
The new type of pollution-free high-efficiency vibrating centrifugal concentrator is applicable for selection of monomer gold and the gold in large particles with relatively high specific gravity, presenting a recovery rate of fine monomer gold with a particle size ≥15um from refractory gold ore at least 10% higher than other imported equipment. Since most gold ore contains monomer gold, the new type of pollution-free high efficiency vibrating centrifugal concentrator applies to the gold concentration from most rock and sand gold mines, particularly from refractory gold ore. This machine also presents extremely high economic value for tailings recovery after floatation and cyanidation.
为了提高选金的回收率，在选金的生产流程中使用四台或五台离心机选金，组成一条日处理25吨的生产流水线。在规模化生产中，可以设计安装几条生产线，以满足日处理50吨、100吨和200吨以上的选金生产的需要。
In order to improve the recovery rate, four or five centrifugal concentrators are used in concentration process to establish a production line with a capacity of 25 tons/day. In large-scale production, several production lines can be designed and installed to meet the requirements of gold concentration capacity of 50, 100 and 200 tons.

1、检查整机各连接件是否紧固。接通电源，旋转轴应逆时针转动（正确）。如发现旋转轴顺时针转动（错误），断开电源，将380V的两根火线互换，再接通电源，保证旋转轴逆时针转动（正确）。
1. Check if the connecting pieces of the whole machine are tightly fastened. The rotation shaft shall rotate counterclockwise (correct) when the machine is switched on. In case it is found the shaft rotates clockwise (error), please turn off the power supply and exchange the two 380V live wires and then connect the power supply so as to ensure the counterclockwise rotation (correct) of rotation shaft.
2、停机后，装上选金斗。
