Disadvantages of spiral chutes

The drawbacks of spiral chutes. 1、 The chute sorting includes a slope flow sorting process. Mineral mortar is fed to some inclined grooves or slopes, and under the push of water, the mineral particle group becomes loose and layered. The upper layer of light mineral quickly flows out of the groove, while the lower layer of heavy mineral material stays in the groove or is discharged from the bottom at low speed. After being collected, the selected ore and tailings are obtained. Spiral chutes are mining and beneficiation machines, especially ideal for sand mining on coasts, rivers, beaches, and streams. The equipment has the characteristics of suitable structure, simple installation, small land occupation, simple operation, stable beneficiation, clear ore separation, large processing volume, high efficiency, high concentration of beneficiation, high recovery rate, and reliable operation. There are also advantages such as small weight, preventing dampness, preventing rust, being less prone to corrosion, and strong adaptability to fluctuations in ore feed volume, concentration, particle size, and grade. 2、 Technical principle: The fiberglass spiral chute mineral separator is not limited to stacking on the cross (or tripod) of the support table. The average mineral mortar is slowly fed onto the spiral groove surface through a feeding groove installed at the end of the rotating groove head for sorting. The tail is equipped with a valve type product selection slot, which divides the selection equipment into three types (or four types) according to grade along the radial direction. Change the cutting width of each product by adjusting the orientation of the valve block. The equipment gathering bucket is a concentric circular tube that allows the obtained multi head ore flow to gather and lead out. The cross section of the spiral chute is particularly suitable for the selection of fine ore particles due to changes in the slope of the curve. The third drawback of the spiral chute is its stability and easy control of the sorting process. 2. The allowable variation range of ore concentration is relatively large. 3. High enrichment ratio and high recovery rate. 4. Small footprint and low water consumption. 5. Simple structure without power. 6. Large production capacity. 7. Installation in a simple and easy to understand and operate. 8. Disadvantages of small investment and quick effectiveness. Spiral chutes can be classified into three types according to the particle size of the processed ore: (1) Coarse spiral chutes, The maximum Granularity of ore feeding is more than 2-3 mm, and the maximum can reach 100-200 mm. (2) Sand ore chute, handling 2-3MM particle grade ore materials. (3) Slurry chute, feeding particle size less than 0.074 millimeters. 5、 Field of use. Disadvantages of spiral chute GRP spiral chute is suitable for separating fine iron, ferrotitanium, ferrochrome, ferrosulfur, sand tin, tantalum niobium, placer gold, coal, monazite, Rutile, zircon sand, rare earth and other metal and nonferrous metal minerals with completely sufficient specific gravity difference.
