Descriptions Spiral concentrator is our company's concentrating experienced scientific product, which is the best concentrating equipment, especially for concentrating sand ore in beach, riverside, seashore and stream.The product is made of the fiberglass lined with wear-resistant polyurethane and corundum cover; the advantages are light, moisture proof, anti-rust, wear proof, anti corrosion and no noise, properly suitable for the different feeding particle sizes and grades. It is the domestic advanced level, the new highly effective equipment.

Applications It has been used in to enrichment the particle size 0.3-0.02 millimeters fine grain like iron, tin, chromite, ilmenite, tungsten, zinc, tantalum-niobium, gold, coal , monazite, rutile, zircon and other low-grade ores. The non-metallic minerals which have a big enough specific gravity difference. Features 1. Reasonable structure and small occupation area2. High recovery, high efficiency, and precise separation3. Non-required power4. Light in weight, anti corrosion, rust and wear resistant5. Simple installation and Minimal maintenance requirements6. Low operating cost and long working life7. Reliable running with minimal operator attention8. Strong adaptability to fluctuation of feeding amount, density, size and grade9. The surface of corundum forms strong friction the concentration effect surpass plastic surface  Technical Specificationsour company uses the newest design and a complete set of technology organization produced and strict quality testing to guarantee each specification of spiral separator qualified.We make the serialized with a special kind of grooved spiral separator to be selected by colored, ferrous metal mine, coal chemical industry, coal dressing, sulfur factory as well as the scientific research, the design department, the colleges and universities test chamber.
