LL Spiral Chute

LL Spiral Chute

Spiral chute is a new gravity separation equipment for sorting size 4-0.02 mm fines iron ore, ilmenite, chromite, pyrite, tungsten ore, tin, tantalum and niobium ore, gold ore, zircon, rutile, and other non-ferrous metals, rare metals and non-metallic mineral proportion of differences.

Detailed introduction

  • 1. large capacity (4 to 6 tons / Taiwan hour), sorting grain size (width 0.04mm ~ 4mm), enrichment is high (2.6 to 2.9) and high recovery rate (82.93 ~ 84.91%), can replace several shaker.
  • 2. high-strength fiberglass manufacturing, with high strength, light weight, corrosion proof.
  • 3. simple structure, reasonable design, reliable operation, easy to operate.
  • 4. the sorting process is stable, the particle size of the material to mine for ore concentration and strict requirements, ease of operation and management.
  • 5. inexpensive, significant benefits, low operating and investment costs.

Notes：1. The above technical parameters calculated based on max spiral quantity and max pitch. Specific data is subject to actual machine. 2. The feed concentration (percentage) is not absolute amount. 3. Spiral chute is different from screw pitch and the total height of corresponding spiral chute is also different.

1. The mineral is stable, sub-ore clear, large capacity
2. High efficiency, mineral enrichment ratio, high recovery
3. The amount of ore and concentration fluctuations, size, quality, adaptability
4. Installation is simple, small footprint, easy to operate
5. FRP materials, moisture, rust and corrosion
6. without power, no moving parts, no noise and other advantages.
