According to the spiral blade at the flooding end, there are two type:

1.High weir type: the top side of spiral blade is higher than the flooding level and the center of the blade is lower than the flooding level. This type is used for classification of ore with flooding size between 0.83-0.15.

2.Immersed weir type: the whole spiral blade is immersed in the flooding level of the flooding end. The type is used for classification of ore with flooding size between 0.15-0.07mm.

Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.
