spiral chute Application

Beneficiation spiral chute is mainly composed of ore feeding chute, spiral flute, product interception slot, ore bucket and other parts. Among these parts, the spiral flute is the key component. Beneficiation spiral chute is used to sort the mineral ores whose particle size is 0.3-0.02 mm, such as iron, tin, tungsten, tantalum, niobium, gold, monazite, rutile, zircon and other metals and non-metallic minerals with sufficient proportion.

Superiority of Spiral Chute

1.As for ordinary glass steel spiral chute, due to the expansion of water in rotary motion, dehydration makes it difficult for stratification, increasing the amount of middling and lowering concentrate quality.

2.The beneficiation spiral chute developed by our company is equipped with notch groove in the groove surface, which improves the mineral enrichment ratio and the recovery rate of heavy minerals. The recovery rate of heavy mineral is increased by 10% than the same model common spiral chute.

3.Beneficiation spiral chute is featured with stable operation, high production capacity, high recovery rate, light weight, strong adaptability to mineral ores, etc.


Working Principle of Spiral Chute

Set up the spiral chute by spiral stents, calibrate vertical line, fix it with iron stand, send the minerals into the two feeding chutes, add the additional water, and regulate pulp concentration. The pulp will swirl downward and it will produce a centrifugal force of inertia in the rotating velocity. According to the proportion of ore, particle size, shape differences, under the role of gravity and centrifugal force, the mineral ores will be separated from sand. The concentrate will be discharged into concentrate bucket and the tailings will be sent into pump, completing the whole beneficiation process. Beneficiation spiral chute is often used in conjunction with the 6S shaking table for further purification.

Structural Features of Spiral Chute

1.Spiral groove is the main part of equipment and the flight made of FRP is bolted together.The inner surface of the spiral grooves is coated with wear-resistant lining.

2.In the top of the spiral groove, there are ores separation machine and ore feeding chute, at the bottom of the machine, there are product interception part and ore discharging chute.

3. Entire equipment is set up vertically with the channel. Cross-section of the spiral grooves is cubic parabola.The slope of the curve is particularly suitable for fine particulate material sorting.

4.Beneficiation spiral chute is featured with simple structure,no moving parts,easy to manufacture,light weight and easy installation and maintenance.
