Alluvial Gold Spiral Chute Mineral Processing Spiral Chute

Product Description

Alluvial Gold  Spiral Chute Mineral Processing Spiral Chute

1.Spiral chute

The spiral chute is used for gold ores,silver ores, placer mines,lead zinc ores, copper ores, tin ores, ilmenite, pyrite,hematite, limonite, chromite, ferberite, tungsten ores. tantalite ores, coal ores, monazite, Sapphire barite, futile, zircon,and silica sands. The sprial chute is the ideal equipment for gravity selecting for the ferrous & non-ferrous metal, non-metallic ores and rare earth ores. It has the advantage of simple structure, light weight, no need power, saving water &electricity, easy to control and high capacity.

 

2. Advantages of gravity spiral chute

1. Reasonable structure, convenient installation 2. Small area and stable mineral processing 3. Clear classification and large processing capacity 4. High efficiency, high enrichment rate 5. High recovery rate and smooth operation 6. Wide adaptability to feed and concentration

 

3.spiral chute Structure :
Spiral chute consists of ore feeding uniform splitter, feed chute, spiral groove, Product interception groove, product gathering bucket and groove bracket (include cross or tripod) six parts.

4.Spiral chute Work principle 
"As larger and heavier particles sink to the bottom of the sluice faster and experience more drag from the bottom, they travel slower, and so move towards the center of the spiral. Conversely, light particles stay towards the outside of the spiral, with the water, and quickly reach the bottom. At the bottom, a "cut" is made with a set of adjustable bars, channels, or slots, separating the low and high density parts. Many things can be done to improve the separation efficiency, including: -changing the rate of material feed -changing the grain size of the material -changing the slurry mass percentage -adjusting the cutter bar positions -running the output of one spiral separator (often, a third, intermediate, cut) through a second. -adding wash water inlets along the length of the spiral, to aid in separating light minerals -adding multiple outlets along the length, to improve the ability of the spiral to remove heavy contaminants -adding ridges on the sluice at an angle to the direction of flow."
