Patent number: 4073951Abstract: Method for agglomerating finely divided particulate solid materials which are capable of agglomerating by intersurface moisture for inter-particle adherence. A mass of the particulate material in a cool atmosphere in an agglomeration zone is simultaneously agitated and subjected to electromagnetic radiation to cause the free moisture contained within the particles to appear in liquid state at the surfaces of the particles so that, with the agitation causing random particle-to-particle contact, agglomeration by inter-particle adherence occurs in the same manner as if extraneous moisture had been introduced. Advantageously, radio frequency energy is employed to accomplish dielectric heating of the moisture within the particle, the moisture escaping to the surface of the particle but persisting there in liquid state because the solid matter of the particle is not heated to a temperature such as to cause unduly rapid vaporization of the moisture.Type: GrantFiled: August 25, 1976Date of Patent: February 14, 1978Inventor: Ralph G.
