Advantages and disadvantages of spiral classifiers and …

Spiral classifier is a kind of mechanical classifier, which consists of a U-shaped sink, a spiral device, a transmission device, a lifting mechanism, and a supporting bearing. The working principle of the spiral classifier is: after grinding, the ore slurry is discharged from the ore feed port of the spiral classifier into the U-shaped groove.
