The term spiral separator can refer to either a device for separating slurry components by density (wet spiral separators), or for a device for sorting particles by shape (dry spiral separators. Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density

The centrifugal concentrator rotates at a high speed, generating a high "G" force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables. In recent years, the application of centrifugal force has proved to be an

01.01.2016· In the spiral concentrator the length of the sluicing surface required to bring about segregation of light from heavy minerals is compressed into a smaller floor space by taking a curved trough and forming into a spiral about a vertical axis. The slurry is fed into the trough at the top of the spiral and allowed to flow down under gravity. The spiraling flow of pulp down the unit introduces a

Flow chart of magnetic sepration process for ore beneficition: using this theory, the spiral classifier will wash and classify the fine ore particles. The grit is then captured/concentrated and discharged into the spiral classifier where each component can process, is shown below in Chart 1. Classifier .

26.05.2016· Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates coarse and fine solids, carried in liquids, with a high degree of accuracy and with lowest possible power and maintenance costs

Mechanical classifiers (i.e. spiral and rake classifiers) are used when the particle sizes are considered to be too fine for screening. Hydro-cyclones (Cyclones) are used for de-sliming, de-gritting and thickening to separate at finer sizes than most screening and classification equipment. Separation and Concentration ALS Metallurgy employs a number of different techniques to separate and

Get Price01.01.2015· Spirals are used all over the world to produce a variety of mineral concentrates, including iron ore fines. In some instances, several stages of spiraling may be required to achieve grade and recovery targets. These may include rougher, scavenger, cleaner, and recleaner steps. Often, spirals are used in conjunction with other fine ore technologies such as hydrocycloning and hindered settling

Spiral jet mills have a static air classifier integrated into the mill housing, whereas fluidised bed opposed jet mills are equipped with a dynamic deflector-wheel classifier. The fineness is set as a function of the classifying wheel speed. All-important is a high product loading of the nozzle jets in order to achieve a high concentration of particles and thus high impact probabilities. The
