选金用粗粒溜槽作为低品位砂金的粗选设备,具有结构简单,投资少,无药剂污染等优点,但其劳动强度较大,回收率较低,约为50%-60%,
这种粗粒溜槽的结构:槽体为钢板或木板制成的长槽,长度在4m以上,宽为0.4-0.6m。高为0.3-0.5m,在槽底有钢制或木制的横向网格状的挡板,槽底每隔0.4m设有角钢制造的横向挡板,有的还在挡板下面铺置一层粗糙铺面,如苇席,毛毯,毛毡,长毛绒布等。槽的安装坡度一般为5度-8度。
Choose gold with coarse sluice as low grade gold roughing equipment, has simple structure, less investment, no chemical pollution, etc., but the labor intensity of the larger, and the recovery rate is low, about 50% - 60%,

The structure of the coarse sluice: long groove is made of steel or wood, the length is more than 4m, the width is 0.4-0.6m. High 0.3-0.5m. At the bottom of the groove is made of steel or wood horizontal grid baffle, groove bottom every 0.4m with angle steel manufacturing transverse baffles, some still baffle below laid a layer of pavement roughness, such as reed mat, blankets, blankets, plush cloth and so on. Groove installation slope is generally 5 degrees -8 degrees.
