Spiral Concentrator


Working Principle 

Glass fiber reinforced plastics spiral concentrator is a kind of advanced gravity separation equipment with high efficiency. It is used for processing fine-grained minerals of iron, tin, tungsten, niobium, gold, coal, monazite, rutile and zircon with particle size 0.3-0.02m, as well as other metal and non-metallic minerals with obvious difference of specific gravity.

Advantages and Characteristics

1. High recovery, high efficiency, and precise separation;

2. Non-required power;

3. Light in weight, anti corrosion, rust and wear resistant;

4. Low operating cost and long working life;

5. Strong adaptability to fluctuation of feeding amount, density, size and grade;

 

6. The surface of emery forms strong friction the concentration effect surpass plastic surface.
