Introduction

Spiral concentrator is a new gravity separation machine. With the water and action of gravity friction force, minerals would be separated by the different gravity and get heavy, middling and light products.

Spiral concentrator is made of the fiberglass lined with wear-resistant polyurethnane and corundum cover, with feature of anti corrosion, rust and wear resistant.
It's the most suitable equipment for mining and ore beneficiation, especially for placer mining at seaside, riverside, sand bank and stream bank. It is of low water consumption, small floor area, high concentration and recovery ratio, high adaptability, etc.



Application

It's applicable to metal and non-metal ores with adequate density difference, like iron, chromite, pyrite, tin ore, tungsten, tantalum, niobium, gold ore, colliery, monazite, rutile and Zirconium.
It can easily adopt to different raw material size, density, ore grade and feed volume. Spiral chute is suitable for treatment of 0.6-0.03mm lode and placer, but high mud content is bad for separation. At present, spiral chute has been widely used in the treatment of iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside placer and gold ore.

Working Principle

1) Stick up the spiral chute, adjust vertical line, and fix it to a proper place with hob ore timber.
2) Deliver the ore slurry to the two feeding opening at top of the spiral chute with the help of sand pump, add supplementary water to adjust slurry thickness. 
3) Then slurry flows down automatically and rotarily from the top. Ore and sand can be divided under rotary steam and centrifugal force according to the slurry's different specific gravity, grain size and shape. 
4) Next, final ore flows to the final ore hopper and coveyed out by pipe and picked up, and final sand flows to final sand hopper and coveyed out by pipe to sand pond. Then remove the sand pump. That is the whole concentrating process.

Structure

1. Reasonable structure and small occupation area.
2. High recovery, high efficiency, and precise separation
3. Non-required power
4. anti corrosion, rust and wear resistant
5. Simple installation and Minimum maintenance requirements.
6. Low operating cost and long working life.
7. Strong adaptability to fluctuation of feeding amount, density, size and grade
