Advantages and Disadvantages of Spiral Concentrator and Its Application
The advantages of the spiral concentrator are: (1) The structure is simple, there are no moving parts, the equipment is easy to manufacture, and the maintenance is simple; (2) The production capacity per unit area is large, and the floor space is small; (3) The material zoning is obvious, and the selection index is more High, the recovery rate is generally about 90%; (4) strong adaptability. When the amount of ore, the concentration of the ore, the size of the ore and the grade of the ore are changed, the impact on the selection index is small.

The disadvantage is that the enrichment of the flaky ore is not as high as that of the shaker and chute. Its own parameters are not easily adjusted to accommodate changes in the properties of the ore.
The spiral concentrator is suitable for the treatment of alluvial sand deposits, especially for those with high separation of useful mineral monomers and flatness. For the residual or sloped sand ore, the recovery rate is low. In addition, the treatment of ore with a higher mud content will reduce the quality of the concentrate. Therefore, it is required to remove the mud and classify and then enter the spiral concentrator.
Spiral concentrator machine for processing cassiterite, scheelite, iron ore chromium, titanium, iron, zircon and monazite and other minerals, may also be used to recover heavy mineral flotation tailings. It is generally used as a roughing equipment, and most of the tailings can be discarded to obtain a coarse concentrate.
The particle size range of the spiral concentrator is generally 2~0.05 mm, the maximum is 6 mm, and the effective particle size is 1~0.1 mm.
A spiral chute of the same type as a spiral concentrator is suitable for processing fine materials and is successfully used to treat extreme lean iron ore. Tests have shown that the effective recovery particle size of the spiral chute is limited to 20 microns.
The difference between the spiral concentrator and the spiral chute is the difference in the cross-sectional shape of the spiral groove: when selecting materials of 2 to 0.074 mm, the cross section of the spiral groove generally adopts a parabola or an ellipse with a large radius of curvature (long axis and short axis) The ratio is 2). Because the radius of curvature of the bottom of the groove is large, the distribution of the ore particles is wider, and the separation of light and heavy minerals is more significant, and it is more adaptable to changes in operating conditions. The spiral chute is a cubic parabolic cross section, which is actually close to a slanted straight line ( 5 ° angle to the horizontal), suitable for sorting materials of 0.074 to 0.02 mm.
