Spiral concentrator is a high-performance equipment designed for the efficient processing of placer ores found in beaches, riversides, seashores, and streams. It is widely used in the concentration of fine particles ranging from 0.3 to 0.02 mm, including iron, tin, chromite, ilmenite, tungsten, zinc, tantalum-niobium, gold, coal, monazite, rutile, zircon, and other low-grade ores. The device is particularly effective for non-metallic minerals that have a significant difference in specific gravity.
Key Features:
- **Reasonable structure** with minimal space requirements
- **High recovery rate** and efficient separation
- **No power required** for operation
- **Lightweight**, corrosion-resistant, and wear-resistant
- **Easy installation** and minimal maintenance
- **Low operating cost** and long service life
- **Reliable performance** with minimal operator attention
- **Strong adaptability** to fluctuations in feed quantity, density, particle size, and grade
- **Superior concentration effect** due to the friction created by the emery surface
Description:
The spiral concentrator is a specialized product developed by our company, known for its excellent performance in sand ore concentration, especially in beach, riverside, seashore, and stream environments. It is constructed using fiberglass lined with wear-resistant resin and an emery cover. This design ensures durability, moisture resistance, rust protection, and noise reduction, making it suitable for various feed sizes and grades. The equipment represents the advanced domestic standards and is considered one of the most effective concentrating machines available.
