Jaw Crusher(2014) Screens and cyclones in closed grinding circuits.pdf.,In 2004 the metallurgical processes were reengineered to increase plant capacity, and this included replacing cyclones with high frequency screens (Aquino B and J Vizcarra 2007). By 2007 the grinding circuit capacity had been increased from 138 tph to 243 tph. The circuits and the operating conditions in 2004 and 2007 are shown in Figure 8.Nexa Resources adopts Fruitful Outotec highfrequency ,520 Nexa decided to test a mixed classification system, integrating hydrocyclones and highfrequency screens in one of its grinding circuits, Circuit C, in a cyclone cluster and ball mill. Fruitful Outotec was chosen as supplier and evaluation partner. Circuit C reconfiguration was performed in early and included a tryandbuy approach.
