The separation efficiency of Na-bentonite by hydrocyclone ...

28/04/2010  Application of hydrocyclone separation at higher percent solids deteriorates the separation efficiency due to the high swelling nature of Reşadiye sodium bentonite. Hydrocyclone operation at low solid ratio requires the hydrocyclone to operate at lower feed pressures up to 1.1 bar (15 psi).
