This spiral chute is the ideal equipment for mining or selection mine, especially in seashore, riverside, sand beach or creek. This machine has the features reasonable structure, simple installation, small occupation, easy operation, stable and clear selection, large capacity, high efficiency, high enrichment selection ratio and recovery, stable running, etc.
The spiral chute is a gravity separation equipment that makes use of the inertial centrifugal force generated by the ore pulp in the spiral rotation motion to separate light and heavy minerals. Spiral chute, integrated the characteristics of spiral concentrator, shaking table and centrifugal concentrator, is the best equipment for mining and beneficiation, especially for placer mining on seashores, riversides, sand beaches, and streams. This equipment is suitable for the separation of iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphonite, tungsten ore, tin ore, strontium as well as antimony ore and other non ferrous metals, rare metals and non metallic mineral bodies with different specific gravity with a particle size of 0.3 0.02 mm. 1. It has advantages of simple installation, reasonable structure less occupied areas and easy operation. 2. It has a big handling capacity with high efficiency, concentration ratio and recovery rate. 3. Besides, it has the foll...

The main part of the spiral chute device is the spiral flight which is made of glass fiber reinforced plastic. The inner surface of the spiral groove is coated with a wear resistant lining, usually a polyurethane wear resistant glue or an epoxy resin mixed with artificial gold steel sand. There are a miner and a feed tank in the upper part of the spiral chute, and a product interceptor and a collecting tank in the lower part. The entire equipment is framed vertically with steel frames. The working characteristics of the spiral chute are that the fine, medium and tailings are respectively taken at the end of the tank, and no washing water is added during the sorting process.
The spiral chute is similar to the thread shape. The movement of the materials inside can be divided into three stages, which are the material introduction stage, material acceleration phase and material uniform velocity warehouse phase. And the third stage lasts the longest, which is the key for materials crushing. The key to the design of the spiral chute is in the uniform velocity stage. The main parameters are radius R, bottom plate width b, elevation height h, helix angle mouth, and bottom plate radial inclination angle. The parameter selection of the spiral chute should be calculated according to the condition of the warehouse, the particle size, the moisture, the number of materials, and the like. Constructional detail of spiral chute
Spiral chutes are widely used in the selection of hematite, the recovery of heavy minerals in tailings, and the selection of rare and non ferrous metals. This is because it has the following advantages:
The sand pump sends the ore to the two feed inlets at the upper end of the screw, and adds supplemental water to adjust concentration of the ore pulp. The ore pulp naturally swirls from high to downward, generating a kind of inertial centrifugal force in the rotating slope. As the slurry flows down the spiral direction, minerals with the highest specific gravity move to the inner edge of the spiral while light materials move to the outer edge of the spiral. According to the difference in the specific gravity, particle size and shape of the ore, the ore and sand are separated by the gravity and centrifugal force of the swirling flow. The concentrate flows into the concentrate bucket. The tailings flow into the tailing bucket which is connected to the sand pool with the pipe and then they are discharged with the sand pump, completing the whole process of dressing.
