The advantages of spiral sorter and nylon spiral chute are:

① The utility model has the advantages of simple structure, no moving parts, easy manufacture and simple maintenance

② Large production capacity per unit area and small floor area

③ The material zoning is obvious and the sorting index is high

④ It has strong adaptability. When the ore feeding amount, ore feeding concentration, ore feeding particle size and raw ore grade change, it has little impact on the separation index.

The disadvantage is that the enrichment ratio of flaky ore is not as high as that of shaking table and chute, and the parameters of wood body are not easy to adjust to meet the ore feeding properties.
