The glass fiber reinforced plastic centrifugal extractor is adopted in extraction transformation of metal compounds, which can increase service efficiency of extracting agents, increase productivity of equipment and facilitate separation of impurities during washing process. By virtue of the heat generated during the saponifying process, the temperature of the organic phase is increased and the viscosity is reduced. The centrifugal extractor achieves the phase splitting effect by a centrifugal force, and can be applied to highly-viscous organic phases under the same process conditions. The retention volume of materials in the centrifugal extractor is reduced, and the temperature of the organic phase can be increased under high-speed stirring conditions.
