A pulverulent, water-soluble material is agglomerated by projecting the material in a stream through a moistening zone. Means are provided for directing an aqueous gas towards the stream of particulate material in the moistening zone so that the stream of particulate material is surrounded by and confined throughout its path of travel through the moistening chamber as particles of the particulate material are moistened and fused, and means are provided for drying the material. Means are also provided for feeding a cooling gas and/or a stream of steam adjacent to and about the periphery of the stream of material.
