1. spiral concentrator Descriptions:
We supply full sets equipments for processing zircon sand, iron sand, ilmenite, chromite ore, tantalum etc.
It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream.
Spirals are made of polyurethane lined fiber glass with wearable corundum inner surface.
Generally there are 5 turns in one start, single, twin, triple and quad starts available per column to suit capacity requirements.
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.
LL Series Spiral Concentrator is applied to iron, tin, tungsten, tantalum, niobium, gold, coal, monazite, rutile, zircon and other metal, nonmetal minerals with enough specific gravity dispersion of granularity ranged from 0.03 to 0.3mm.
High recovery n efficiency
Precise separation
Non-required electricity
Light in weight, anti corrosion, rust and wear resistant
Simple installation and Minimal maintenance requirements
Low operating cost and long working life
Reliable running with minimal operator attention
Strong adaptability to fluctuation of feeding amount, density, size and grade
The surface of corundum forms strong friction concentration effect surpass plastic surface
3. spiral concentrator Working Principle
The sand pulp is first send to the two inlets of the spiral chute. After added water for appropriate pulp density, the pulp swirls down and generates a centrifugal force which separates the ores and sands. The ore concentrate flows into the hopper and is collected through a pipeline. The tailings are discharged by a sand pulp. Thus, the whole mineral process is finished.

| 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. |
