Spiral Separator

Spirals are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream. í¦Gandongí¦ Spirals are made of polyurethane lined fiber glass with wearable corundum inner surface. Generally there are 5 turns in one start, single, twin, triple and quad starts available per column to suit capacity requirements.

1. Overview Spiral chute is a new type of gravity concentration equipment for separating 0.6-0.05mm (can separate 2mm material under special circumstances) fine particle ore, including iron, ilmenite, chromite, pyrite, tungsten, tin, tantalum-niobium, alluvial gold, zircon, rutile, monazite, phosphorus and other non-ferrous metals, rare metals, non-metallic minerals with specific gravity difference. Spiral chute with advantages of stable dressing, clear separating, large capacity, high efficiency, strong adaptability to feeding capacity, density, granularity, fluctuations of grade, simple installation, small footprint, simple operation, moisture-proof, antirust , corrosion, no power, no moving parts, no noise, etc., it is particularly suitable for placer extracting in seaside, river, sand beach, and stream. 2. Structure Spiral chute is mainly composed of 9 parts as the following picture shows. And its main six types of models are with diameters of 2000mm, 1500mm, 1200mm, 900mm, 600mm, 400mm(laboratory use).

Spiral chutes of the wet type, also called Spiral Chute, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag). The Spiral Chute consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

Spiral classfiers in pioneers machinery factory suitable for dewatering, medium, desliming and spraying in ore dressing for medium and fine naturial wet and dry classifying in mine. Pioneers classifying machine is mainly used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 14-325 meshes are classified. Waste mud or water for ore sand can be separated from the ores.

Beneficiation spiral chute integrates features of spiral concentrator, shaking table, and centrifugal separator. It the best equipment for mineral processing, especially used for mining sands in coastal, river, sand beach, river road, etc. Beneficiation spiral chute is adapted to process alluvial deposit, especially flat materials with high monomer dissociation degree of useful minerals. Besides, since minerals containing high mud have low concentrate quality, so they must be de-slimed and graded before entering into the beneficiation spiral chute. The working features of beneficiation spiral chute is that the concentrate, middling and tailings are gotten at the end of the equipment, and the sorting process does not need washing water. Spiral chute is the main component of the device, which is made of polyurethane wear-resistant plastic or mixed artificial corundum resin. Its liner is made of FRP a wear-resistant material. On the top end of beneficiation spiral chute, there is a mineral separation device and a feed tray; at the lower part of beneficiation spiral chute, there is a products interceptor and a trough for receiving ores. The whole equipment by pioneers manufacturer stands vertically though still frame.

Taking into consideration the requirements of our industrial customers, we are manufacturing� Industrial Servo Motor. These processing plants make the beach sand fine in texture, separating it from impurities. Spiral separator, shaking tables, agitator, magnetic roll separator and other equipments are installed in the plant. Depending upon the site and the productivity scale, we custom engineer this� Industrial Servo Motor.

Supplier: Shaking table, spiral separator, saw-tooth wave ladder jig.

Jigging machine belongs to gravity-based equipments, which can separate mineral based on differing of specific gravity. Gandong saw-tooth wave jig is mainly consist of three parts: main frame, driving set and jigging chamber. Application Jigging machine is widely used in gravity concentration of tin, tungsten, placer gold, hematite ore, manganese, titanium, antimony, lead, tantalum, niobium and other minerals. Features The pulsing curve of the traditional jig is sinusoidal waveform, the up and down speed of water flow and acting time produced by the movement of membrane are almost same, so it is unfavorable to loose of jig bed and layering of minerals based on special gravity, and thus affect separation ability and recovery rate. Saw-tooth wave is energy economy gravity equipment that is developed and improved from traditional jig on the basis theory of jig bed layering. Its jigging pulsating curve is similar to saw-tooth wave, which makes the up speed of water flow quicker than down speed of water flow, so it can improve looseness of jig bed and reduce suction action, which can lead to fully settlement of heavy particles in slurry, it highly improves separation ability and recovery rate. Stroke and frequency of stroke are adjustable.

Application of shaking table Concentrating Tables are designed to wet gravity-based separation of minerals and other granular materials. There are many applications where the concentrating table is of particular value and cannot be equaled for economical and efficient performance. They are effective in processing precious and base metal, rare metal and non-metallic minerals. Construction Head Motion: The head motion is of rugged construction and requires minimum maintenance. Its internal mechanism is splash lubricated from an integral oil sump. Decks: The decks are built of 16 mm zircon-reinforced fiberglass with fabricated steel frames at the bottom and are easy to clean, requiring little maintenance. The specific gravity of fiberglass made into decks is one third of that of steel, while its strength reaches as high as 70% that of steel. This fiberglass desks also has the characteristic of water-resistance and corrosion-resistance and can hold the shape unchangeable at f+50f¦. Feed and Water Box: A wooden feed distributing box with hopper and a long water box are attached to the iron of the deck, giving a very even distribution of feed and water. Base: A choice of ordinary type, groove steel support or big channel steel support is available. Technical Specification The Gandong Shaking Tables have three distinct deck designs available. The course ore deck is designed for recovering particles sized from 0.5 mm to 2 mm; the fine sand deck is designed for recovering fine particles in the range of 0.074 mm to 0.5 mm; the slime deck is designed for recovering super extremely fine particles in the range of 0.05 mm to 0.074 mm.
