Acceptance Standard for Coal Mine Spiral Chutes 1. Overview Gravity beneficiation spiral chutes summarize the characteristics of fiberglass spiral chutes, fiberglass spiral chutes, shakers, and centrifugal beneficiation machines. After being evaluated and passed by relevant scientific research, design, universities, and mining departments organized by the Ministry of Metallurgical Industry, they are recognized as having superior performance and advanced selection indicators, and have been awarded the Science and Technology Research Achievement Award by the Ministry of Metallurgical Industry. They are now in the field of non-ferrous metals Ferrous is very suitable for a large number of applications. This equipment is suitable for separating fine and small materials with Granularity of 0.3-0.02mm to obtain iron, Ilmenite, Chromite, pyrite, zircon, Rutile, monazite, phosphorus and ethylene, tungsten ore sand, cassiterite, tantalum, niobium ore and other non-ferrous metals, rare mineral metals and this non-ferrous metal ore body with different specific gravity. 2、 The usage method is to make the fiberglass chute stand up, align it with the vertical line, fix it in the appropriate position with an iron frame or wood, and send the sand ore to the two feeding ports on the top of the spiral through a slurry pump. The water is added and the mineral slurry concentration is adjusted. The mineral slurry naturally swirls from high to low, and an inertial centrifugal force occurs in the rotating inclined flow rate, which is distinguished by the gravity, particle size, and state of the mineral sand, By utilizing the gravity or centrifugal force of the swirling flow, 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 mortar pump, completing the entire beneficiation process. Acceptance Standard for Spiral Chutes in Coal Mines III. Features This machine is suitable for sorting 0.3-0.02mm fine materials into iron ore, Ilmenite, Chromite, pyrite, zircon sand, Rutile, monazite, phosphorus, tungsten, tin, tantalum, niobium 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. Acceptance standard for spiral chute in coal mine IV. According to the Granularity of processed ore materials, the chute can be divided into three categories: (1) coarse spiral chute. The maximum particle size of feeding is more than 2-3mm, and the maximum can reach 100-200mm. (2) Mineral sand chute, processing 2-3 millimeter sized ore. (3) Slime spiral chute, feeding Granularity<0.074mm. 5、 The fiberglass spiral chute is suitable for processing 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.
