The document summarizes the benefits and working principles of spiral chutes used for mineral beneficiation. Specifically: 1) Spiral chutes developed by the company have notch grooves that improve mineral enrichment and recovery rates by 10% over common spiral chutes. 2) Spiral chutes separate minerals from sand using gravity and centrifugal force as materials spiral downward, with concentrates discharged and tailings removed. 3) Spiral chutes have a simple structure with no moving parts, making them easy to manufacture, install and maintain.

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.

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.
