Hydrocyclone Working Principle - Mineral Processing & Metallurgy The CYCLONE PRESSURE becomes a control indicator for the adjustment of the apex size and the volume of the feed. The vortex finder is a FIXED VARIABLE, meaning that it can be changed to affect the sizing of the overflow, but not as a normal operating practice. The cyclone must be removed from service and taken apart to make that adjustment.
