ABSTRACT:
Process for the accelerated drying of cement mixes includes the application to the cement mixes of electromagnetic microwaves. The device for the accelerated drying of cement mixes includes a chamber in the form of a tunnel, defined by a supporting framework in which are accommodated cement mixes, preferably on a casting bed, and microwave generator, in the form of a plurality of magnetrons supported by vertically adjustable cross members. The magnetrons are provided with telescopingly adjustable waveguides having an outlet in the chamber, and the supporting framework is slidable on a track.
