Spiral chute is a kind of equipment that combines the characteristics of spiral concentrator, spiral chute, shaking table, and centrifugal concentrator. It is mainly used in mining and mineral processing, especially in sand mining on the seashore, riverside, sand beach, and stream channel.
The spiral chute is a device that integrates the characteristics of a spiral concentrator, a spiral chute, a shaking table, and a centrifugal concentrator. It is mainly used in the field of mining and mineral processing, especially for sand mining on the seashore, riverbank, beach, and stream.
The spiral chute has a reasonable structure, simple installation, stable sorting process, easy control, a wide range of feed concentration changes, high enrichment ratio, high recovery rate, small footprint, low water consumption, simple structure, no power required, large processing capacity, simple installation, convenient operation, small investment, and quick results.
The spiral chute is suitable for sorting fine-grained materials with a particle size of 0.3~0.02mm, including iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphate ore, tungsten ore, tin ore, tantalum ore, niobium ore, and various non-ferrous metals, rare metals, and non-metallic ore bodies with different specific gravities.

The spiral chute does not require an external power source during operation. It relies on the gravity of the material itself and the centrifugal force generated by rotation for sorting.
The spiral chute can effectively classify and separate materials according to their physical properties such as specific gravity, particle size, and shape.
The spiral chute has good adaptability to changes in parameters such as feed volume and feed concentration.
Compared with other ore dressing equipment, the spiral chute occupies a smaller area, but the productivity per unit area is very high.
The spiral chute is equipped with a spiral shaft inside, which is usually located at the bottom of the chute body and is driven to rotate by an electric motor or other power device. The spiral blades are fixed to the spiral shaft, which acts like a spiral propeller when rotating, pushing the materials together.
Material movement and classification
1. Material movement: When the spiral shaft rotates, the spiral blades push the materials to rotate together and move forward along the bottom of the chute. The design of the spiral blades allows the materials to gradually move upward as the spiral shaft rotates.
2. Classification process: During the movement process, the materials are classified according to their physical properties such as size, weight, density, and shape. Larger and heavier materials move forward relatively quickly and are discharged from the discharge port of the chute body; while smaller and lighter materials move forward relatively slowly and eventually discharge through the discharge port, but may go through a longer path and more classification processes.
