Abstract: The present invention relates to a continuous process for producing ferti lizer granules. The process is particularly suitable for producing fine-part icle fertilizer granules. The fertilizer granules are produced in a mixer ha ving a horizontal cylindrical mixing chamber and a fast-rotating shaft that is centrically arranged in said mixing chamber and that is equipped with mix ing tools. The invention further relates to the granulated fertilizers obtai nable by this process, and to the use thereof for fertilizing agricultural a nd/or horticultural crops.

Abstract: A multi-trace element fertilizer which contains magnesium as a further nutrient and in which the complex-forming trace elements are present in the form of anionic chelates with one or more N-carboxyalkylaminoacids is prepared by a process wherein the N-carboxyalkylaminoacids are reacted, in the presence of water, with the trace elements or trace element compounds in a molar ratio of N-carboxyalkylaminoacids to trace elements or trace element compounds of not less than 0.8:1, at least 20% by weight of the trace element compounds being oxides, hydroxides and/or carbonates. At the same time, or subsequently, the pH of the solution is brought to 3.5-6 by adding a member selected from the group consisting of magnesium oxide, hydroxide and carbonate. A maximum of 50 equivalent percent of the magnesium compound may however be replaced by a member selected from the group consisting of alkali metal oxides, hydroxides and carbonates and ammonia.

Abstract: Production of granular fertilizer (I), comprises: (A) supplying powdered fertilizer to a mixer; (B) continuously supplying liquid binder while operating the mixer and vortex generator; (C) carrying out the mixing process until granules of the required size are obtained; and (D) removing and drying the granules. Production of granular fertilizer (I), comprises: (A) supplying powdered fertilizer to a mixer having an annular, non-rotating mixing region, a central mixer carrying mixing tools occupying most of the mixing space and a rotating vortex generator in the mixing tool region; (B) continuously supplying liquid binder while operating the mixer and vortex generator at suitable rotation speed and peripheral velocity; (C) carrying out the mixing process until granules of the required size are obtained; and (D) removing and drying the granules.

Abstract: In a process and an apparatus for the joint purification in a wash column (VII) by means of a washing liquid (5) of the waste gases (1,3) and/or vapors (2) formed in the production of inorganic fertilizers, the waste gases (1,2,3) introduced into the wash column are sprayed with a wash liquid (11) after their entry into the lower part of the wash column. The column is typically a filled column with waste gas distribution elements disposed below the filler and spray nozzles near the distributors.
