Spiral Chute is the best equipment for mining and mineral processing, which combines the characteristics of the spiral concentrator, shaking table and Centrifugal concentrator. It is made of the fiberglass lined with wear resistant polyurethane and corundum cover, light moisture proof, anti rust. It is mainly used for separation and recovery of ...
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.

Spiral chute produced by FTM
The gold content in the gold deposit is extremely low, and it is usually necessary to use refining by gravity separation, flotation, amalgamation, magnetic separation and electro selection, and at the same time, high efficiency and energy saving gold ore beneficiation equipment are arranged for beneficiation and enrichment. Spiral chute on working site In January 2016, a customer with a gold mine in Indonesia wanted to import a set of gold beneficiation equipment from China. After many investigations and comparisons, the user finally chose FoteHeavy Industry, and our engineers also quickly equipped the user with a complete set of mineral processing equipment. Crushing equipment: Jaw crusher.It is flexibly used for gold ore crushing according to different gold selection requirements, further improves gold mining efficiency and recovery rate, and reduces gold mine loss rate. Washing:Some gold mines have a high mud content, and the soil is very sticky. It is easy to wrap the gold grain...
