Nesans Spiral Classifier consists of an open trough with a chute provided for the input feed material. Before being fed into the spiral classifier, the dust from the screen is mixed with water and it is carried to the input chute through a slurry pump. The inlet flow is evenly distributed across the surface area of the spirals.
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
