6 Factors That Affect Hydrocyclone Performance
— Shorter Cyclones make coarser cuts because the material has less time in the Cyclone before discharge. The length of a Cyclone is determined by the conical sections, or extended feedboxes, and cone angles. A 10-degree cone angle makes it a longer Cyclone, while a 40-degree cone angle makes it a shorter Cyclone.
