A nebulizer for liquids, particulate materials or liquids/solids suspensions, comprising, within a vessel (10) containing a reservoir (11), an upright duct (13) with a plurality of circumferentially spaced outlet apertures (20), enclosing a coaxial air line (14) feeding a plurality of jets (16) duly aligned with outlet apertures (20) in the upright duct (13) so that an annular column of material is drawn from reservoir (11) to be dispersed by entrainment in the air streams from the jets (16). Larger droplets may return to the reservoir (11) while the smaller fraction issues from the vessel through an outlet (12). The relatively large outlet apertures (20) and the large cross-sectional area of the column of the material prevent blockage at the nebulizer head.

A device for producing a particulate dispersion comprising at least one duct to contain a supply of a fluid material to be dispersed, a plurality of outlet apertures communicating with said at least one duct and directed normal to the longitudinal axis of said at least one duct, and a plurality of pressurized gas jets aligned with the outlet apertures to draw material from said at least one duct and to form a dispersion of the material which is thus forced through the apertures, characterized in that the cross-sectional area of each outlet aperture is not greater than the cross-sectional area of the at least one duct communicating therewith, and wherein at least a part of the at least one duct is located upright in a vessel for containing a reservoir of the fluid material to be dispersed, an open bottom end of the at least one duct being located such that it will be submerged within the material in use.
