Spiral chute sorting of sand and gold 1. Introduction: The chute beneficiation belongs to the slope flow sorting process. Mortar is fed to some inclined grooves or slopes, and under the push of water flow, the mineral particle group becomes loose and layered. The upper layer of light minerals quickly flows out of the groove, while the lower layer of minerals with high specific gravity remain inside the groove or are discharged from the bottom at a low speed. After separation and collection, selected minerals and tailings can be obtained. The spiral concentrator is a machine for mining and beneficiation, making it ideal for mining ore in bays, river beds, sand banks, and streams. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear separation, large processing volume, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture resistance, rust prevention, corrosion resistance, and strong adaptability to fluctuations in feed volume, concentration, particle size, and grade. 2、 The production principle is that the evenly proportioned mortar is slowly fed onto the rotating groove surface through a feeding chute installed on the spiral groove head for sorting. The tail end of the spiral groove is equipped with a valve type product acquisition groove, and the selected equipment is divided into three types according to grade along the radial direction. By adjusting the orientation of the valve block to change the cutting width of each product, the equipment gathering hopper allows the selected variable mineral flows to converge and export differently. The transverse plane and slope of the curve of the fiberglass spiral chute vary greatly, and the applicable range is for the selection of fine particle materials. Spiral chute separation of sand gold III. Features This machine is suitable for separating 0.3-0.02mm fine materials to obtain iron ore, Ilmenite, Chromite, pyrite, zircon sand, Rutile, monazite, phosphorus, tungsten, tin ore, tantalum, niobium ore and other non-ferrous metal ores, rare metals or non-metallic ore bodies with different density and specific gravity. This machine has the advantages of stable selection process, easy operation, wide range of feed density, ultra-high enrichment ratio, high recovery rate, small land area, low water consumption, simple structure, no need for power, large output, simplified installation, easy operation, low investment, and quick effectiveness. Spiral Chute Sorting Sand Gold 4. The structure of the spiral chute is composed of six parts: a feeding homogenizer, a feeding trough, a rotating trough, a product acquisition trough, an equipment gathering hopper, and a trough bracket (including a cross or triangular frame). The spiral groove formed by connecting the spiral pieces is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and connected together by screws. The selection surface of the rotating groove has a pre made wear-resistant layer. She has the advantages of lightweight, sturdy, and durable consumer goods that are not easily damaged. The head of the spiral groove is equipped with a multi tube feeding homogenizer to sort minerals evenly, which is not cumbersome to operate. The mineral sorting device is freely placed on the cross (or tripod) of the support table. The evenly divided mortar is slowly fed onto the surface of the spiral groove through the feeding chute at the head end of the rotating groove for sorting. The tail of the rotating groove is installed in a valve block type new product selection groove, allowing the selection of new equipment to be divided into three (or four) types of new products radially according to grade. Change the cutting width of each new device by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that distinguishes and converges the obtained multi head ore flows. The horizontal plane of the spiral concentrator is particularly suitable for the separation of small particle ore materials when the slope of the curve changes. Spiral chute separation of gold 5. Scope of use Spiral concentrator is suitable for separation of fine grained iron ore, Ilmenite, Chromite, pyrite, sand tin ore, tantalum niobium ore, placer gold, coal, monazite ore, Rutile ore, zircon sand, rare earth ore and other metal and non-metallic mineral materials with sufficient density ratio difference. spiral chute sorting sand and gold
