Drawing 1: Introduction to the spiral chute with a 1.6-meter belt. The chute selection includes the inclined flow sorting process. 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 characteristic spiral concentrator has attracted more attention among many gravity separation machines due to its low power consumption, simple structure, small land occupation, simple operation, stable beneficiation, clear mineral sorting, no moving parts, easy maintenance and management, strong processing capacity per unit area, and other characteristics. Machinery with relatively wide or flat groove surfaces and large areas of laminar flow of mortar are more suitable for processing medium to fine (-4MM) sized ores. China has made spiral chutes with diameters of 400, 600, 900, and 1200 millimeters, Ф The production capacity of 1200mm four heads is approximately 4-6 tons per hour. Drawing 4 of a 1.6 meter spiral chute with a belt. The structure of the fiberglass spiral chute consists of six parts: a feeding homogenizer, a feeding chute, a spiral groove, a product cutting groove, an equipment gathering hopper or groove bracket (including a cross or triangular frame). The rotating groove connected by the rotating disc is a key component. The spiral plate is made of fiberglass (fiber reinforced coal gangue) and connected together by bolts. The sorting surface of the spiral groove has a pre made durable and wear-resistant layer. He also has the advantages of lightweight, strong, and durable consumables. The head of the rotating groove is equipped with a multi tube feeding homogenizer to sort minerals evenly, which is easy to control. The ore separator is not restricted from being placed on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through a feeding groove installed at the end of the spiral groove head, and selected for operation. The tail end of the spiral groove is installed in a valve block type new product selection groove, allowing the sorting equipment to be divided into three types (or four types) of new products along the radial direction according to grade. Change the acquisition width of each new product by adjusting the position of the valve block. The new equipment gathering bucket is a concentric circular tube that converges and leads out the intercepted multiple ore flows. The lateral plane of the spiral concentrator and the change in slope of the curve are particularly suitable for the selection of small particle ore materials. Drawing 5 of the 1.6-meter spiral chute with a belt. Scope of application: The fiberglass spiral chute is suitable for handling 0.6-0.03mm and vein and placer ores, but it is unfavorable for sorting when the mud content is high. It is now widely used for processing iron ore, tungsten, tin, niobium tantalum ore, coastal and river sand, and placer gold, among others. Drawing of a 1.6 meter spiral chute with a belt
