A continuous mixer for liquids comprises a casing having a conical interior surface and a discharge outlet at the apex of the cone formed by the conical interior surface, a rotor that rotates at its center on the axis of the cone and has a conical exterior surface whose vertical angle is approximately equal to the vertical angle of the conical interior surface, a pressure-transport device that has one or more feed lines which communicate with a gap between the interior surface of the casing and the exterior surface of the rotor a position removed from the discharge outlet and that delivers one or more liquid inputs under pressure through the feed lines, and a gap-adjustment device capable of axially adjusting the rotor within the casing to adjust the gap. The internal pressure and temperature or the mixer can be controlled or adjusted while the rotor is rotating by changing the gap width along the axial direction.
