Abstract
In a high-speed centrifugal extractor of the type wherein an inlet for a mixture of heavy liquid and light liquid is disposed at the bottom of a cylindrical rotor rotating at a high speed, a heavy liquid outlet and a light liquid outlet are disposed at the upper part of the rotor and a weir for facilitating selective extraction of the heavy liquid and a weir for facilitating selective extraction of the light liquid are disposed at the upper part of the rotor in order to guide the heavy liquid phase and the light liquid phase separated inside the rotor by centrifugal force to the heavy and light liquid outlets, respectively, an improvement resides in a spiral liquid path formed inside the cylindrical rotor and extends from the mixed liquid inlet to the selection weirs so that the mixture of the heavy and light liquids introduced from the mixed liquid inlet rises along the spiral liquid path while rotating therein.
