Spiral Classifier

Products Display

• High-weir Spiral Classifiers

  High-weir spiral classifiers feature a relatively high discharge weir at the lower end of the trough, resulting in a deeper water pool in the classification zone.

  This design is suitable for classifying coarse particles (typically with a cut size of 0.15 mm or larger) and is often used in primary grinding circuits. The deeper water pool allows for better separation of coarse particles, which settle rapidly, while fine particles are carried away by the overflow.

• Submerged Spiral Classifiers

  Submerged-spiral classifiers have a lower weir, and the spiral blade is partially submerged in the water at the lower end of the trough.

  This design creates a more turbulent environment in the classification zone, making it effective for classifying finer particles (with a cut size as small as 0.075 mm). Submerged-spiral classifiers are commonly used in secondary grinding circuits or in applications where precise classification of fine particles is required, such as in flotation feed preparation.
