**Product Specifications**
The spiral chute is a gravity separation device widely used in the mining industry. It is ideal for processing various types of non-ferrous metals, rare metals, and non-metallic minerals, such as iron ore, gold ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorite, tungsten ore, tin, tantalum, and niobium ores.
**Working Principle:**
The spiral chute operates under the influence of water flow, gravity, inertial centrifugal force, and friction. Slurry is fed into the top of the spiral through a distributor, ensuring even distribution across the spiral channels. As the slurry moves down the spiral, mineral particles settle and are separated based on size, density, and to a lesser extent, shape. Lighter particles are carried outward by the water flow, while heavier particles move inward, allowing for efficient concentration.
**Advantages and Features:**
- ISO 9001:2008 certified
- Approved Safety Certificate for Mining Products
- Longest manufacturing history in China
- Self-developed technology
- Professional technical team with extensive experience
- High recovery rate, high efficiency, and precise separation
- No need for power supply
- Strong adaptability to fluctuations in feed quantity, density, particle size, and grade
**Technical Parameters of Spiral Chute:**
Model NO.: DI1200
