Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand. The spiral chute has the characteristics of reasonable structure, simple installation, small footprint, simple operation, stable ore beneficiation, large processing capacity, high efficiency, high concentration ratio, high recovery and stable operation. In addition, it has the advantages of light weight, moisture proof performance, rust protection, corrosion resistance, high adaptability and low noise. When the ore pulp flows near the carved groove edge, vortex will be generated; ore bed will be thickened at the same time, which strengthens the loose stratification effect and the coarse but light minerals separated out from the middling band cross the groove to move outwards. The bottom heavy mineral flows to the inner edge along the groove guide. As a result, the middling quality ore volume decreases and the concentrate metal recovery rate is improved.

  The sand pulp is first send to the two inlets of the spiral chute. After added water for appropriate pulp density, the pulp swirls down and generates a centrifugal force which separates the ores and sands. The ore concentrate flows into the hopper and is collected through a pipeline. The tailings are discharged by a sand pulp. Thus, the whole mineral process is finished.
