Product Description

Spiral Screw Classifier Separator Machine


FLG spiral classifier is the most commonly used classifying equipment nowadays. It classifies the minerals by taking advantage of the different settling velocity of mineral particles with different size, shape, and density.


FLG spiral classifiers are widely used for separation plant. They can be combined with ball mill to form a closed circuit for preliminary classification and check classification, sometimes they can be applied for ore washing, de-sliming and de-watering as well.


There are high-wearable type single and double spiral classifier, and immersed type single and double spiral classifier, standard and extended type spiral classifier.

Working principle

The ground pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise and overflow, while the coarse particles sink to the bottom of tank and are pushed upward by the spiral.
