Grooved spiral chutes 1. Introduction: Spiral chutes summarize the characteristics of gravity beneficiation spiral chutes, fiberglass spiral chutes, shakers, and beneficiation centrifuges. After relevant scientific research organized by the Ministry of Metallurgy, and appraisal conducted by departments such as design, school, and beneficiation company, they have been recognized as having superior mechanical performance and advanced sorting indicators, and have been awarded the Science and Technology Research Achievement Award by the Ministry of Metallurgy Industry. They are now in the field of non-ferrous metals Ferrous is widely used. This machine is suitable for separating iron, ferrotitanium, chromite ore, pyrite, zircon ore, Rutile, monazite, phosphate rock, tungsten sand, placer tin, tantalum niobium ore, niobium ore and other nonferrous metals, rare mineral metals and nonferrous metal ore bodies with specific gravity difference from fine materials with Granularity of 0.3-0.02mm. 2、 The average working principle of the slurry passes through the head of the spiral groove and is slowly fed to the rotating groove surface for sorting. The tail of the spiral groove is equipped with a valve type equipment to obtain the groove, and the sorted products are 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 equipment, the product gathering hopper allows the selected multi-directional mineral flow to converge and lead out. The slope change of the horizontal plane and curve of the spiral concentrator is very suitable for the selection of fine particle materials. Grooved spiral chute III. The characteristics of FRP chute, such as low power consumption, simple structure, small area occupied, simple operation, stable beneficiation, clear ore separation, no need for moving parts, convenient Computerized maintenance management system, and large processing output per unit size, have attracted much attention in many gravity beneficiation equipment. The machinery has a relatively wide and gentle groove surface, and the slurry flows in a laminar flow with a larger area, making it more suitable for processing medium to fine (-4mm) ore particles. We have made spiral chutes with diameters of 400, 600, 900, and 1200mm domestically, Ф The processing capacity of 1200MM four head is about 4-6 t/h. grooved spiral chute 4. According to the size of ore processed, the chute can be divided into three types: (1) coarse grained chute. The maximum Granularity of ore feeding is above 2-3MM, and the maximum can reach 100-200MM. (2) Sand ore chute, processing 2-3 mm particle grade ore material. (3) Slurry spiral chute, feeding particle size < 0.074mm. Grooved spiral chute 5. Use This equipment is suitable for separating fine and small materials with Granularity of 0.3-0.02MM to obtain iron ore, Ilmenite, Chromite, pyrite, zircon sand, Rutile, monazite, phosphorus ethylene, tungsten ore, tin ore, tantalum, tantalum niobium ore, and other nonferrous metals, rare mineral metals or nonferrous metal mineral bodies with different specific gravity. grooved spiral chute
