Gravity Equipment Spiral Separator Working Principle

India 200 tons per hour zircon rutile ilmenite beach sand project.

Beach sand main contents :
Gold, Ilmenite, Rutile, Zircon, Tin, Hematite, Magnetite, Andalusite, Quartz, Corindone, Atlri, Garnet, Monazite, etc.
Customer' target: remove  magnetic minerals and get the high grade rutile, tin and Zircon, more important to high recovery gold ore. 

We design the processing flowchart as below:

1. Use sand pump feed material directly to spiral separator.  If there are some bigger stones in deep areas, can consider use trommel screen to separate out particles +2mm

2. Spiral separator:  use two-stages spiral separator, first stage is for rough concentration, the middling from first-stage will go to second-stage to concentrate again to get high recovery ratio.

3. Most of the heavy fractions are magnetic minerals, so in order to remove clean as much as possible, it is better to firstly use our factory special designed four rollers wet magnetic separator to remove magnetite ilmenite and hematite and weak magnetic ore.

4. the gold and zircon and other non-magnetic minerals goes to shaking table for concentration, also use two stages shaking table for getting higher concentration effect.

5. after the electrostatic separator, can get rutile and other minerals, maybe still including some magnetic minerals, so use a high intensity dry process magnetic separator to  remove the magnetic minerals again, the zircon will be more high grade up to 66% for sale a good price. 

We design different process flowchart depends on customer's actual mining condition.

2). Shaking Table:

Shaking table for sale is one of the main equipments of gravity concentration. Gravity Concentration Equipment is not only widely applied on separating tungsten, the tin, the tantalum niobium and other rare metals and the noble metal ore. Also widely used in separation for Gold, Silver, Tin, Columbium, Tantalum, Titanium, Barium, Tungsten, Iron, Chrome, Manganese, Zircon, Lead, Zinc, Mercury, Copper, Aluminum, etc. The shaker effective recycling granularity scope is 2-0.037 millimeters.

Working Principle
The working principle of shaking table for sale is to use the combined action of the specific gravity difference of sorted minerals, alternating movement of bed surface, and transverse oblique water flow and riffle (or notch groove), to allow loose layering of ores on the bed surface and fan-shaped zoning. Then different products can be produced.
