Hydrocyclones - an overview | ScienceDirect Topics

Cleaners are classified as high, medium, or low density depending upon the density and size of the contaminants being removed. A high density cleaner, with diameter ranging from 15 to 50 cm (6–20 in) is used to remove tramp metal, paper clips, and staples and is usually positioned immediately following the pulper.

Cyclone - Wikipedia

In meteorology, a cyclone (/ ˈ s aɪ. k l oʊ n /) is a large scale air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure.

Hydrocyclone Working Principle

The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take inside the cyclone. The centrifugal force ( the central Hydrocyclone Working Principle ) that is generated by this spin, forces the "bigger particles outwards towards the wall of the cyclone.
