1. Overview of Spiral Chute
If you are looking for more details, kindly visit our website.
Spiral chute is a widely used equipment in the mineral separation process, primarily utilizing the density differences of mineral particles to achieve separation under the influence of gravity and centrifugal force. It is commonly used for the concentration of iron ore, gold ore, chromite, and other minerals.
2. Working Principle
The separation principle of the spiral chute is based on the movement of mineral particles along the spiral-shaped chute under the combined action of gravity and water flow. Lighter particles are carried away by the water, while heavier particles slide down along the inner side of the chute, resulting in the separation of minerals with different densities.
3. Structure and Components
The main components of a spiral chute include the feed inlet, spiral chute body, separation surface, support frame, and tailings outlet. The feed inlet introduces the slurry, the spiral body manages the flow and separation of the slurry, and the tailings outlet discharges the separated waste material.
4. Applications of Spiral Chute
Spiral chutes are widely used in the fields of mineral processing, coal, chemicals, and building materials. They are particularly suited for processing fine-grained ores and are often used for the concentration of iron ore, chromite, ilmenite, gold ore, and zircon sand.
5. Operational Tips
To ensure optimal performance of the spiral chute, operators should carefully control the slurry concentration and flow rate, maintaining a stable feed rate. The chute angle and water flow should also be adjusted according to the characteristics of the ore.
6. Maintenance and Care
Keefam supply professional and honest service.
- English: Regular maintenance of the spiral chute is essential, especially in high-wear and corrosive environments. It is recommended to inspect the spiral body for wear and tear regularly and remove any accumulated mineral particles to prevent clogging and ensure separation efficiency.
7. Advantages of the New Spiral Chute
Compared to traditional fiberglass spiral chutes, our new spiral chute features a special polymer coating, offering extended lifespan and superior wear resistance. It resists cracking under high temperatures and provides a higher enrichment ratio, significantly boosting production efficiency.
8. Common Issues and Solutions
Common issues with spiral chutes include excessive slurry flow rates, clogging, or suboptimal separation results. To address these problems, operators should adjust the feed rate, clean the chute surface regularly, and replace key components if necessary.
Conclusion
Spiral chutes are crucial in the mineral processing industry. By optimizing its structure and surface materials, the durability and efficiency of the equipment can be significantly improved. The new spiral chute not only enhances production efficiency but also reduces maintenance costs, making it an ideal choice for mining operations.

The ore is sent to the two feed openings on the top of the screw, add supplementary water, adjust the concentration of ore paddle, The ores naturally swirl downward from high. An inertial centrifugal force is generated in the rotating flow of the inclined plane.The specific gravity, particle size and shape of ore.By swirling gravity and centrifugal force,The ore and sand are separated, the concentrate flows into the concentrate hopper and is piped out, and the tailings flow into the tailings hopper is piped into the sand tank and discharged, completing the whole process of mineral processing.
