Abstract

The apparatus for applying powder enamel to ceramic tiles includes a closed housing (2) containing powder enamel dispersed therein. Aspirator means are connected to the housing (2) and take out a flow of mixture containing air and powder enamel in solution from the housing (2),. to send it under pressure toward an applicator (4). The applicator includes a half-spherical cap nozzle (45), in which a delivery notch (47) is made for delivering the above mixture of air and enamel in solution, with a preestablished aperture angle, onto a plurality of tiles (100) passing in a application chamber (5). The aperture angle can be adjusted by adjusting means (10).
