The invention relates to a method and a drop former for producing tables made of mixtures of a plurality of materials. The method for producing tablets made of mixtures of a plurality of materials, particularly urea mixtures, having the following steps: - producing a liquid melt of a first material, - adding at least one further material in solid or liquid form to the melt for producing a mixture, - output of drops of the mixture onto a steel belt by means of a drop former having a rotating, perforated outer drum, - solidification of the drops of the mixture on the steel belt into tablets, wherein the at least one additional material is mixed into the liquid melt in liquid form immediately before the drop former or into the liquid melt in solid form upstream of a two-stage heated grinding and mixing unit, wherein the mixture within the drop former is agitated within a feed channel of the drop former, arranged within the rotating outer drum before its discharge through nozzles and openings of the rotating outer drum by means of an agitator extending within the drop former. The method and the drop former can be used for producing fertilizer, for example. |
