Hydrocyclones are almost universally used in grinding circuits because of their high capacity and relative efficiency. They can also classify over a very wide range of particle sizes (typically 5–500 μm), smaller diameter units being used for finer classification. However, cyclone application in magnetite grinding circuits can cause ...

5. CYCLONES CAN HAVE A CUT SIZE MEASURED IN MILLIMETRES The myth is busted. Although hydrocyclones can treat particles measured in millimetre sizes, it does not mean that hydrocyclones have cut points measured in millimetres, but rather in microns (µm) and normally below 200 µm. For larger sizes, normal screening should be used.
