According to Chaves and Peres (2002), "...whether or not to use a cyclone or spiral classifier is not a matter of indifference. The spiral classifier is more efficient than the cyclone", so, the ideal situation, in the grinding circuit, would be to have the efficiency of the spiral classifier, but using cyclones as they simplify the layout. 376

Beneficiation of Fine Iron Ores using the Desand Process
The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine (<0.010 mm) clay-rich slimes simply …

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.
