Abstract
An atomizer wheel for use in a spray drying apparatus comprises an interior annular liquid supply chamber, from which a number of substantially radial ejection ducts extends towards the external surface of the wheel through a length constituting a considerable portion of the radius of the wheel. The ducts discharge into a downwardly open annular discharge slit at a comparatively short distance from an external wall connected with a wheel cover and whose inner wall surface forms an axial-symmetrical surface of revolution with a substantially linear generatrix forming an angle of not more than 15.degree. with the axis of revolution. The comparatively steep slit wall ensures together with the large length of the ejection ducts that the liquid is atomized at the outlet of the discharge slit with a considerable downwardly directed axial velocity component so that the spray characteristics resembles those of nozzle atomization but with preservation of the general advantages with respect to flexibility and reliability of operation associated with wheel atomization.
