ABSTRACT:
Agglomeration of particles of a pulverulent water-soluble material is achieved by conveying a layer of the material on a porous surface towards which a laminar flow of heated humid air is directed. A reduced pressure is applied from beneath the porous surface for drawing the heated humid air to contact the conveyed material for a time sufficient for fusing particles of the material at micropores formed at points of contact between the surfaces of the particles.
