In mineral processing, metallurgy and tailings recovery applications, the spiral chute is widely used for fine-grained mineral separation due to its simple structure, stable performance and low operating cost. Its working principle relies on physical gravity separation without chemical reagents, supporting environmentally friendly production.
The core of spiral chute operation lies in the combined effect of gravity, centrifugal force and water flow friction, which separates mineral particles of different specific gravity and particle sizes. Slurry is evenly fed from the top and flows downward along the spiral trough. Heavy valuable minerals concentrate toward the inner side, while light gangue and impurities move to the outer side. At the discharge end, concentrate, middlings and tailings are collected separately to achieve continuous separation.
The whole operation process requires no extra power except gravity, featuring low energy consumption, low noise and low failure rate. The spiral chute adopts a modular structure, making installation and adjustment convenient. It has strong adaptability to fluctuations in slurry concentration and particle size, ensuring stable and reliable separation performance for continuous production lines.
It is widely applied in the separation of iron, tin, tungsten and other metallic ores, as well as tailings retreatment and non-metallic mineral purification. With its practical design and stable working performance, the spiral chute provides a cost-effective and easy-to-maintain separation solution for mines and resource recycling projects.
