Spiral chute is a new type of gravity beneficiation equipment, which is suitable for sorting iron ore, ilmenite, chromite, pyrite, tungsten ore, tin ore, tantalum sawn ore, placer gold, zircon, rutile, monazite, phosphoethane and other non-ferrous metals, rare metals and non-metallic minerals with specific gravity differences with particle size of 0.6-0.05mm (in special cases, it can separate < 2mm). With the development of beneficiation technology, the chute plays a major role in the whole mineral separation process: enriching heavy minerals, throwing away most of the tailings at one time, reducing the use of other equipment during subsequent cleaning operations, reducing equipment investment, reducing the floor area of the concentrator, improving the separation capacity, etc. Spiral chute has the advantages of stable beneficiation, large processing capacity, high efficiency, strong adaptability to the fluctuation of ore feeding volume, concentration, particle size and grade, simple installation, small floor area, simple operation, moisture-proof, rust proof, corrosion-resistant, no power, no power parts, no noise, etc., and is especially suitable for placer mining in seashore, riverside, sand beach and stream.
