The hydrocyclone finds application in many industries
ranging from pharmaceuticals to mineral processing. For
the present research, a hydrocyclone design applied for
the separation of china clay fines from grinding mill
product has been investigated. In this instance, the china
clay product is represented by the fine particle fraction
(overflow, rp < 1 lm, r the radius). The course fraction
(underflow) includes quartz and mica materials (rp > 1
lm). As depicted in Fig. 1, the hydrocyclone design under
consideration (Appendix A), features a single tangential
inlet to the hydrocyclone head (cylindrical),
which generates an outer downward helical-flow towards
the underflow and within this, an upward central helicalflow
towards the overflow
