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, moistureproof 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 following table lists the contrast results of Gongchangling feint hematite ore’s grade sand setting industrial test (one coarse, one concentrated process) done by spiral chute with and without carved groove.
1. Fine discharge particle, better finished product particle, less powder, cheaper price.
2. Can reach better efficiency by crushing hardness material, especially for pebble.
3. Long lifespan of wearing parts.
4. Small footprint, easy operation, durable working hours, reliable performance, simple maintenance, simple structure.
