manufacturing process of triple superphosphate (tsp) and complex fertilizer granules, ru00c9actionnel granulation - drying device, and packaging of the product and process release.

摘要

the present invention relates to a manufacturing process of triple superphosphate (tsp), granules (up to 47% of total p2o2) from rock phosphate and phosphoric acid. the invention takes into account the different parameters involved in the kinetics of the reaction of attack between phosphate and phosphoric acid to give a mono calcium solution.this solution is used to generate a single channel in an installation, triple super phosphate granules containing phosphorus in the form of a water soluble and citrate, available to plants. in addition, the present invention is aimed at overcoming the limitations of the method (1100).technical characteristics of 817 imposed by the previous facility, and therefore proposes a more flexible approach in terms of production capacity, from the point of view of the quality of the fertilizer is produced.the present invention provides a process for the production of phosphate fertilizer granules based on the most recent technological advances.relating to: - the soubilisation optimized phosphate in acid solution, the slurry granulation phophorique mono calcium - drying of the granulated product resulting in a more sophisticated device, the separating of the granulated product, the recycling of the product itu and big (milling) in a new equipment of granulation, the treatment of sortan gasts of the sector to meet the environmental standards for pollutants in multi - layer - the washing storage and mixing of granular tsp in appropriate areas of the finished product packaging, separate
