The present invention relates to a device for feeding a granular or powderlike material to a pressing apparatus for the dry pressing of the material. The device comprises containers (10) for the materials and rollers (11) arranged at openings of the containers (10). Each roller (11) has a cavity which is suitable to be filled by the material and to be freed of the material following a rotation of the rollers (11) so as to pour the material into a mold (14). In the method, the rotation of the rollers (11) is produced simultaneously with a movement of the rollers (11) in a direction which lies at right angles to its axis. The invention allows to obtain particular color effects, such as colorings, color shades, basic decorations, complex decorations, natural stone-like effects, et cetera, on the resulting ceramic products, particularly tiles.
