subject: Spiral Separator In Classifier Equipment [print this page] The term classifier5.html">spiral separator can refer to either a device for separating slurry components by density, or for a device for sorting particles by shape. Here, these are termed wet and dry spiral separators, respectively.
Classifier (Classifiers):One type of Ore spiral classifier in China spiral classifier. For an optimum system, Classifier is essential that the maximum amount of product is recovered from the grinding mill discharge at the required size, and that fine particle that adhere to the coarse particle returns are effectively washed clear from this stream.
The materials have different fall velocity in the liquid for the different particle size and proportion. The fine mineral particles will float in the water, and the coarse mineral particles will sink on the bottom. By means of this theory, the classifier can mechanical grade the materials. After grading and filtering the milled powder, the coarse materials will be sent to the feeding mouth by the spiral vane, and the fine materials will be discharged from the overflow pipe. The base of this machine is made of channel steel; the body is welded by steel plate. The spindle nose covered with pig iron has wear-resistant and durable. The lifting devices have electric type and manual type.
This machine is widely used for distributing ore in the close circuit with ball mill, grading ore in the flow of metal ore-dressing and desliming and dehydrating in the washing. It is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with particle size less than 3mm, and is also used for removing iron in the coal, non-metallic and building materials.
Spiral separator(Screw classifier):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 as well as the particle's hydrodynamic properties (e.g. drag). The device 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. Usually, and the spiral separator can be divided into two types, the wet spiral separator and the dry spiral separator.
The wet spiral concentrator, also called spiral concentrator, is a device to separate solid components in slurry, based upon the different density of solid particle as well as the particle's hydrodynamic properties. The device 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. Dry spiral separators, capable of distinguishing round particles from nonrounds, are used to sort the feed by shape. The device consists of a tower, around which is wound an inwardly inclined flight. A catchment funnel is placed around this inner flight. Round particles roll at a higher speed than other objects, and so are flung off the inner flight and into the collection funnel.
Spiral Classifier: is widely used for classifying all kinds of mineral according to the particle size in the mineral processing flow, and is also applicable for desliming and dehydrating in the mineral washing work. Generally, Classifier forms a closed process flow with ball mill. The classifier has the advantages of scientific structure, reliable working stability, and convenient operation, etc.
