Description

Introduction
Spiral classifier is referred to as classifier, is one of the equipment in mineral processing. Classifier is a kind of classification device that depends on the principle--different solid particles proportion has different precipitation speed in liquid to classify minerals. It can filter out the minerals grain and powder after grinding. So that the coarse materials are screwed into the feed inlet of the mill, while the fine materials are discharged from the overflow pipe.

Advantages

  • 1
    Unique structure Operation cost is low;
  • 2
    Easy operation High degree of automation.

Structure

With the aid of the principle that the solid particle size is different and the specific gravity is different, the settling velocity of solid in the slurry is different. The fine solid is discharged at the overflow weir，and the coarse particles sink to the bottom, driven by the spiral and discharge from the upper end of the classifier.
