Particle Sizing Systems: Hydrocyclones
March 14, 2005
Particle Sizing Systems' SuperClone line of hydrocyclones is unique in its ability to simultaneously remove both fines and coarse particles from a powder or slurry. The standard hydrocyclone uses centrifugal sedimentation to separate particles based on size and density. A hydrocyclone consists of a cylindrical section on top and a funnel section underneath. Particles under pressure enter the top of the cyclone (the cylindrical section) tangentially and travel down into the funnel section. As this occurs, the larger and denser particles are forced to the outside while the smaller particles remain in the center. The larger, denser particles eventually leave through the outlet in the funnel, also referred to as the underflow. The finer particles are carried by a secondary vortex back up to the cylindrical section where they leave through the outlet in the chamber, called the overflow. The SuperClone Hydrocyclones have an additional outlet in the cylindrical section that allows the finer particles to be separated into two size fractions.
