Disclosed is a vortex-based centrifugal separator for removing solids from a liquid/solids fluid stream in two stages. A fluid stream under pressure is introduced at the top of the cylindrical separator at a tangential angle forming helical downward flow. The first stage uses a centrally-located spin plate for reversing the cleaner interior flow of the vortex back upward, while the heavier solids settle at the bottom of the chamber for periodic removal. In the second stage, a plurality of louvered slots in an upper discharge pipe remove finer solids from the exiting upward fluid flow prior to discharge.
