The groove structure of spiral chutes: 1. Overview: Gravity separation is widely used in the beneficiation of metal and non-ferrous metals due to its low pollution and low cost. Spiral chute is one of the gravity beneficiation machines, characterized by a cubic parabolic cross-section, suitable for processing finer particle sizes of -0.2 millimeters. During the sorting process, there is no need to add water for flushing, and the end of the chute is divided into sections to select fine, medium, and tailings. 2、 Set up the spiral concentrator by using the method, calibrate the vertical line, fix the iron frame or wood at a suitable position, send the sand ore to the two ore inlets on the spiral top by the sand pump, add water, and adjust the concentration of the mineral slurry. The mineral slurry naturally swirls from high to low, generating a coherent centrifugal force in the flow rate of the whirling inclined surface, and obtaining the difference in the density, specific gravity, Granularity and shape of the mineral sand, Through the influence of the gravity of the swirling flow and the centrifugal force, the ore and sand are separated. The selected ore flows into the concentrate hopper and is piped out, while the tailings flow into the tailings hopper and are moved to the sand pit through a pipeline. Then, they are discharged by a sand pump, completing the entire beneficiation process. The grooving structure of spiral chute  螺旋溜槽的刻槽结构 III. Features This machine is applicable to the separation of fine and small materials with a particle size of 0.3-0.02mm to obtain iron ore, ilmenite ore, chromite ore, pyrite, zircon, Rutile ore, monazite ore, phosphate ore, tungsten ore sand, tin, tantalum niobium ore, niobium and other non-ferrous metal ores, rare ore metals or non-metallic mineral bodies with density and specific gravity differences. This product has the advantages of stable and simple selection process, wide range of ore concentration tolerance, high enrichment ratio, high recovery probability, small land area occupation, low water consumption, simple structure, no power, large processing capacity, simplified installation, simple operation, small investment, and quick results. The groove structure of the  螺旋溜槽的刻槽结构 spiral chute is composed of six parts: a feeding homogenizer, a feeding chute, a rotating groove, an equipment selection groove, a product gathering hopper, and a support bracket (including a cross or triangular frame). The spiral groove formed by connecting rotating discs is a key accessory. The spiral plate is made of fiberglass (fiberglass reinforced coal gangue), and a wear-resistant layer is pre made on the sorting surface of the rotating groove through bolts. It also has the advantages of lightweight, sturdy, and long-lasting consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer for ore dressing, which is easy to operate. The mineral sorting device is freely placed on the cross (or tripod) of the support table. The evenly divided mineral mortar is slowly fed onto the spiral groove surface through the feeding groove installed at the beginning of the rotating groove for selection. The bottom of the rotating groove is equipped with a valve block type new product acquisition groove, which allows the sorted new products to be divided into three categories (or four categories) of new equipment along the radial direction according to grade. Change the cutting width of each new product by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that gathers and exports the selected variable mineral flows. The cross section and slope of the curve of the fiberglass chute are particularly suitable for the selection of fine particle materials. The groove structure of the spiral chute 5. The spiral chute is suitable for processing 0.6-0.03MM and this vein of ore and sand, but it is unfavorable for sorting when the mud content is high. It has now been widely used in the processing of iron, tungsten, tin ore, niobium tantalum ore, beach and riverbed placer or gold ore, and so on. The groove structure of the  螺旋溜槽的刻槽结构 spiral chute
