Further Information

The Kadant (B.C.I.) Liquid Cyclone / Ruffclone operates as follows:
The stock enters the Liquid Cyclone / Ruffclone through a tangential inlet having a downward slope. Accelerated centrifugal action is affected as the stock spirals downward along the wall contour toward the small end of the cone. The undesirable particles, grit, dirt, metal etc. are forced to the outer wall and carried down and out at the bottom of the cone into a stilling chamber. Here, they are washed and good fibrous material which may have been carried along is reclaimed. Reject material is collected in the chamber at the bottom; cleaned fibres spiral up and exit out the vortex finder at the top of the unit.
