Spiral chute sorting of sand and gold 1. Introduce the beneficiation chute, including the inclined flow sorting process. Mineral mortar is applied to a partially inclined chute or inclined surface. With the assistance of flowing water, the mineral particle group is not tightly fastened and layered. The upper part of the light mineral material quickly flows out of the groove, while the lower part of the heavy mineral material stagnates in the inner groove or slowly flows out from the lower part. After distinguishing and connecting, the concentrate and tailings can be obtained. Spiral chutes are machinery for mining and beneficiation, especially ideal for sand mining in coastal areas, riverbanks, sandbanks, and streams. The product also has the characteristics of reasonable structure, simple installation, small land occupation, simple operation, stable beneficiation, clear screening of ore, large production capacity, high efficiency, high beneficiation enrichment ratio, high recovery probability, and stable operation. It has the advantages of light weight, moisture prevention, rust prevention, strong corrosion resistance, and strong applicability to feed volume and density, Granularity, and grade fluctuation. 2、 Working principle: The fiberglass chute separator does not need to be placed on a cross (or tripod) on a support table. The same mineral mortar is slowly fed onto the rotating groove surface through the feeding chute installed at the head end of the spiral groove, and sorting is carried out. The bottom is equipped with a valve block type product cutting groove, allowing the selected equipment to be divided into three types (or four types) according to grade along the radial direction. Change the selection width of each device by adjusting the orientation of the valve block. The product gathering bucket is a concentric circular tube that converges and induces the obtained variable mineral flows. The transverse section of the fiberglass spiral chute and the change in slope of the curve are extremely suitable for the selection of fine particle materials. Spiral chute sorting sand gold 
III. The characteristics of glass fiber reinforced plastic chute, such as low energy consumption, simple structure, small area occupation, simple operation, stable beneficiation, clear ore separation, no moving parts, convenient Computerized maintenance management system, and strong handling capacity per unit area, have attracted much attention among many gravity separation machines. The equipment has a relatively wide and stable groove surface, and the area where the slurry flows in a laminar flow is large, making it more suitable for processing medium to fine (-4mm) ore particles. China has made spiral chutes with diameters of 400, 600, 900, and 1200mm, Ф The processing capacity of 1200MM four head is about 4-6 tons/hour. The glass fiber reinforced plastic spiral chute consists of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product acquisition groove, an equipment gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove formed by connecting rotating discs is the main component. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue) and is connected together through screws. The sorting surface of the spiral groove has a pre designed durable wear-resistant layer. She has the advantages of being lightweight, sturdy, and durable in using consumables. There is a multi tube feeding homogenizer above the rotating groove to screen minerals evenly, which is not cumbersome to operate. The screening machine does not need to be restricted from being placed on the cross (or tripod) on the support table. The uniform slurry is slowly fed to the surface of the spiral groove through the feeding groove on the rotating groove head, and sorting is carried out. The tail of the rotating groove is installed in a valve type new equipment selection groove, allowing the sorted new products to be divided into three (or four) types of new products according to grade along the radial direction. Change the width of each new device by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that separates and merges the intercepted multi-directional mineral flows. The cross section of the spiral chute and the slope change of the curve are very applicable to the selection of fine materials. Spiral chute is suitable for separating fine grained iron ore, ilmenite ore, chromite ore, pyrite, sand tin, tantalum niobium ore, placer gold, coal, monazite, Rutile, zircon ore, rare earth ore and other gold and non-metallic mineral materials with sufficient specific gravity difference.
