Spiral Classifier

Brief Intro of Spiral Classifier:

Because of the different specific gravity, different types of solid particles precipitate slower or faster in liquid. The spiral classifier is a device based on this principle for mechanical grading.

The ball mill and the following spiral classifier, which is used to grade the ore and the fine silt, form a closed circuit.
