Chute alluvial gold equipment is a in oblique water flow selection method of gold in the chute with, the 1970s various types of chute is selection of the main equipment of alluvial gold, widely used, and now many choose gold factory throw continue to use. Movable chute replaced the original chute, has developed a vibrating, shaking, pulsating, shape from the original strip development become pinched shape, spiral, long spiral and so on a variety of forms.

溜槽沙金设备可分为固定式溜槽、振动溜槽、溜槽筛、可动式机械溜槽和可翻转式溜槽等。溜槽按作业制度分为浅填溜槽（小溜槽）和深填溜槽。前者用于选别粒度小于16mm的沙金矿，后者适用于大粒度沙金矿，给矿粒度可达50～100mm。

Chute alluvial gold equipment can be divided into fixed chute, vibrating chute, chute sieve, movable type mechanical chute and tilting chute. According to the work chute system divided into shallow fill chute (small chute) and deep fill chute. The former is applied to the sand gold deposit with the particle size less than 16mm, which is suitable for the large size sand gold deposit, and the ore particle size can reach 50 to 100mm.

溜槽沙金设备的捕集覆面分为硬、软两种硬覆面为各种形状的格条；软覆面为毡类、有纹橡胶、呢绒铺垫。软覆面溜槽选别的沙矿最大粒度不超过1～2mm。

Chute alluvial gold equipment trap set covering for the hard and soft hard cladding for various shapes of lattice; soft cladding is felt, pattern rubber, cloth upholstery. Soft cladding chute beneficiation of sand mining maximum size of not more than 1 ~ 2mm.

用溜槽沙金设备进行选金的回收率主要取决于按面积或宽度的单位给矿量、矿浆浓度、溜槽倾角、槽面特性、入选物料的金含量和粒度组成。

With chute alluvial gold equipment selecting gold recovery rate mainly depends on according to the area or the width of the flat to ore, pulp concentration, the inclination angle of the chute, groove surface characteristics, selected materials gold content and particle size composition.
