Spiral chutes - one coarse, one fine, one sweeping. Introduction: Chute sorting includes the process of inclined flow sorting. Mineral mortar is fed to a partially inclined chute or inclined surface. Under the driving force of water flow, the mineral particle group is loose and layered, and the lighter minerals in the upper layer quickly flow out of the groove. The heavier minerals in the lower part either stagnate inside the groove or are discharged from the lower part at a low speed. After obtaining the difference, concentrate and tailings are obtained. The fiberglass spiral chute is a machine for mining and beneficiation, especially ideal for sand mining on coasts, riverbanks, sandbanks, and river beds. The equipment has the characteristics of correct structure, simple installation, small land occupation, simple operation, stable beneficiation, clear screening of minerals, large processing capacity, high efficiency, high beneficiation concentration ratio, high recovery probability, and stable operation. There are also advantages such as lightweight, moisture prevention, rust prevention, corrosion resistance, and strong applicability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 Use skills to make the spiral concentrator stand up, align it with the vertical line, use an iron shelf or wood to stabilize it in a suitable position, use the sand pump to transport the ore sand to the two feeding ports on the spiral head, add make-up water, and adjust the concentration of the ore slurry. The mineral slurry naturally swirls from high to low, and an inertial centrifugal force occurs in the flow rate of the swirling inclined surface to obtain the difference in gravity, Granularity and shape of the sand ore, By achieving the efficiency of gravity or centrifugal force through swirling flow, the ore and sand are separated, and the concentrate is discharged into the beneficiation hopper and connected out through pipelines. The tailings flow into the tailings hopper and are connected to the sand pit through pipelines, and then discharged by a mortar pump, completing the entire beneficiation process. The spiral chute is characterized by small power consumption, simple structure, small land occupation, simple operation, stable beneficiation, clear mineral separation, no moving parts, convenient Computerized maintenance management system, large production per unit area and other characteristics. The equipment has a wider and flatter groove surface, and the mortar presents a large laminar flow area, making it more suitable for processing medium to fine (-4mm) particle sized ores. Our country has made fiberglass spiral chutes with diameters of 400, 600, 900, and 1200 millimeters, Ф The processing capacity of 1200MM four head is about 4-6 t/h. The spiral chute of 
consists of six parts: a feeding distributor, a feeding groove, a rotating groove, an equipment cutting groove, a product gathering hopper, and a groove support (including a cross or triangular frame). The spiral groove formed by the connection of spiral plates is a key component. The rotating plate is made of fiberglass (fiberglass reinforced coal gangue) and is bolted together. The selected surface of the rotating groove has a pre designed durable wear-resistant layer. It has the advantages of being lightweight, sturdy, durable, and not easily damaged consumer goods. The spiral groove is equipped with a multi tube feeding homogenizer to divide ore evenly, making it easy to operate. The concentrator is not limited to being 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 chute at the head of the rotating groove for sorting. The tail of the rotating groove is installed in a valve type new product selection groove, and the selected new products are divided into three types (or four types) of new equipment along the radial direction according to grade. Change the width of each new product by adjusting the position of the valve block. The new product gathering bucket is a concentric circular tube that allows the intercepted multi-directional mineral flow to converge and lead out. The cross section of the spiral chute and the different slopes of the curves are very suitable for sorting fine particle materials. Spiral chutes are suitable for separating fine grained iron ore, ilmenite ore, chromite ore, pyrite, sand tin, tantalum niobium ore, placer gold ore, coal, monazite, Rutile, zircon ore, rare earth ore and other metal and non-metallic mineral materials with sufficient specific gravity difference.
