Alluvial gold, produced in the river bottom or low-lying areas, and sand mixed with stones, after screening is gold panning out.

沙金的种类、大小有所不同，那么筛选沙金的设备也有很多种类，下面我们就简单的介绍几种不同的选取沙金的设备。

Alluvial gold type, vary in size, then screening the alluvial gold equipment, there are many types. Next, we will briefly introduce the different selection of alluvial gold equipment.

固定溜槽：固定溜槽是一种非常简单的沙金重选设备，使用也十分普遍。固定溜

Fixed chute: fixed chute is a very simple alluvial gold separation equipment, use is also very common. Fixed slip

槽成本低，使用方便，但是回收率低，所以只用于沙金的粗选。

Trough of low cost, easy to use, but the recovery rate is low, it is only used for roughing gold.

波动溜槽：波动溜槽又称鼓动溜槽，是在普通固定流槽的基础上研究出来的一种

Wave: wave is also called chute chute chute, is a research based on common fixed chute on

新型 砂金矿选设备，鼓动溜槽选取沙金的颗粒小，抓取率比固定溜

The new placer gold equipment chute, selected alluvial gold particles are small, grab rate than fixed slip

槽高，它降低了选矿成本，是比较理想的选矿设备。

Trough height, it reduces the cost of mineral processing, is an ideal equipment for mineral processing.

水套离心机：利用重力加速度原理，研制生产的一种离心选矿设备。适合选取比

Water jacket centrifuge: the use of gravity principle, a centrifugal separation equipment development and production. Suitable selection ratio

较小的毛 细金，水套离心机虽然投资高但是它占地面积小，操作

Fine gold hair small, although the investment high jacket centrifuge but it covers a small area, operation

简单，回收率高。是 现在普遍使用的沙金选取设备

Simple, high recovery rate. It is now commonly used in alluvial gold equipment selection
