చిన్న వివరణ:

 Hydro-cyclone is mainly used in mineral processing as a classifier, and has proved extremely efficient at fine separation sizes. It is used increasingly in closed circuit operations but has found many other uses, such as desliming, deritting and thickening. It has also found wide acceptance recently for the washing of fine coal. Compare with mechanical classifier, it has the advantage of simple structure,a larger production capacity per unit volume, small occupation space, high efficient classification efficiency (up to 80% -90%), fine grading granularity, low cost, less material consumption and so on.
