LL Spiral Chute

Spiral chute

Spiral chute is a combination of the characteristics of spiral chute, spiral concentrator, shaking table, centrifugal concentrating machine, a new type of the first domestic equipment in 1977, developed, is the best equipment in mining, mineral processing, especially the coastal, river, beach, Sand Creek Road placer mining is more ideal. The product has the advantages of reasonable structure, simple installation, small occupation area, simple operation, stable ore beneficiation, clear, large processing capacity, high efficiency enrichment ratio, high recovery rate, reliable operation characteristics. Has the advantages of light weight, moisture, rust proof, corrosion resistance, adaptability to fluctuation of ore quantity and concentration, particle size, grade is strong, has the advantages of no noise etc..

Using The Principle And Method Of:

The spiral chute is erected, the calibration of vertical lines, fixed in position with iron or wood, a sand pump will ore to top two inlet spiral, adding supplementary water, regulating ore oar concentration, ore oar nature from high to swirl, the centrifugal force generated a kind of inertia in the inclined plane in a rotating velocity the difference in the proportion, ore, grain size, shape, by gravity and centrifugal force swirl effect, will be separated from the ore and sand inflow, concentrate concentrate hopper connected with pipeline, flow into the tailings tailings of fighting with the piping to sand pool, and then pump to drain away, the completion of the whole process of the selected mine.
