Abstract

A porous paste, especially a plaster paste or slurry for producing sandwich-type plasterboard, is made in a disk-shaped mixer having a rotor rotatable in a mixing chamber by introducing compressed air or other pressurizable gas through a wall or bottom segment directly into the chamber so that the incoming pressurized gas meets the mixture with a shearing action along the wall or bottom.
