They work using a similar principle to classifying tanks. In fine material screw washers, material enters through a feed box. Heavier grains sink to the bottom of the box, while finer materials float to the surface and over the top. Larger sand grains collect in the bottom of the trough and are lifted up the inclined plane to be discharged by ...

Seperator / Classifier. 1. The basic function of Separators / Classifiers is to separate very fine sized particles from the coarse particles. During the separation process, the separated fine particles are collected at one end as finished product whereas the coarse sized particles are further sent back to undergo the grinding process once again.
