"Engrais complet dissous".
Le brevet principal N 337584 du 4 novembre 1926 concerne un procédé de fabrication d'un engrais complet dissous, dans le- quel un mélange de phosphate naturel à teneur riche en acide phosphorique et carbonate de chaux avec du chlorure de potasse, est mis en réaction avec de l'acide sulfurique,et cette réaction ayant réalisé un milieu acide,on introduit du sulfate d'ammonia- que,les opérations comportant une réduction préalable des phos phates à l'état de très fine division,une réduction plus sommaire du sulfate d'ammoniaque et du chlorure de potasse,le produit de réaction étant convenablementbrassé pour obtenir un mélange in- time;
ce produit de réaction étant laissé au¯repos en vue de solidifier plus ou moins la masse,
<Desc/Clms Page number 2>
après quoi on procède à/la neutralisation de cette masse à l'aide d'un phosphate pauvre en carbonate de chaux,cette masse définitive, après prise et dessination, pouvant "être réduite en une poudre sèche, homogène et stable, non hy- gyroscopique, à l'aide d'un broyeur approprié.
Selon la présente invention, on remplace dans ce pro- cédé l'acide sulfurique par l'acide nitrique, de sorte qu' on obtient un engrais complet dissous à base d'azote nitri -que .
La présente invention poursuit les buts suivants :
1 Réaliser un engrais donnant à la plante une alimenta- tion complète, c'est-à-àdire apportant en même temps et sous une forme aussi assimilable: de l'azote nitrique, de l'azote ammoniacal, de l'acide phosphorique, de la potasse, de la chaux.
2 Offrir à la plante ces divers éléments indispensables, non seulement sous forme dune assimilation tout à fait adé- quate à la nutrition végétale, mais de plus, dans un état d'homogénéité complète. En effet, dans les engrais composés, fabriqués par mélange mécanique, les particules des diffé- rente engrais mélangés ne sont pas unies intimement. Cer - tains distributeurs d'engrais, même les distributeurs basés sur la force centrifuge, opèrent à l'épandage, une sépara- tion mécanique des éléments, qui en rend la répartition fort peu régulière.
3 Réaliser un engrais, dont la réaction ne soit aucune- ment acide, qui soit meme alcaline ou tout au moins neutre.
4 Réaliser un engrais très sec et fin, dont la distribu- tion aux distributeurs mécaniques soit facile, réglable à volonté et bien régulière.
5 Réaliser un engrais non hygroscopique, qui conserve toutes ses qualités intrinsèques de fertilisation, et de
<Desc/Clms Page number 3>
plus, sa facilité d'épandage, grâce à sa siccité.
Les matières premières suivantes sont utilisées dans la fabrication de l'engrais complet dissous nitrique :
1 l'azote sous forme de sulfate d'ammoniaque;
2 l'azote sous forme diacide nitrique;
3 l'acide phosphorique sous forme de phosphate minerai et de superphosphate;
4 la potasse sous forme de chlorure ou de sulfate de potasse.
Les phosphates sont moulus à une finesse aussi grande que possible et au moins une finesse de 85% au tamis N 100
Le sulphate d'ammoniaque et le chlorure de potasse sont moulus assez sommairement, étant facilement solubilisés dans l'acide nitrique.
On introduit dans le malaxeur le phosphate suivi du sulfate d'ammoniaque et du mélange d'eau et diacide nitrique, ce dernier attaquant le phosphate. pour augmenter la teneur en p2 i5 soluble dans l'eau, on y ajoute une proportion dé- terminée de superphosphate. on brasse pendant quelque temps, puis on introduit la potasse de chlorure ou la potasse de sulfate.
.après mélange intime, la masse est évacuée du malaxeur par l'ouverture d'une vanne de vidange. Le produit liquide à cette phase tombe dans la cave. Après un séjour de quel- ques heures la cava peut être vidée.
On procède alors à la désintégration de l'engrais et met le produit en magasin pour séchage à 1 air libre.
Le produit obtenu jouit des mêmes avantages que l'en- grais complet dissous ordinaire repris au brevet principal.

"Complete dissolved fertilizer".
The main patent N 337584 of November 4, 1926 concerns a process for manufacturing a complete dissolved fertilizer, in which a mixture of natural phosphate with a content rich in phosphoric acid and carbonate of lime with potassium chloride, is reacted. with sulfuric acid, and this reaction having produced an acidic medium, ammonium sulphate is introduced, the operations comprising a prior reduction of the phos phates to the state of very fine division, a more summary reduction of the sulphate ammonia and chloride of potash, the reaction product being thoroughly mixed to obtain thorough mixing;
this reaction product being left rest in order to more or less solidify the mass,
<Desc / Clms Page number 2>
after which one proceeds to / the neutralization of this mass with the aid of a phosphate poor in lime carbonate, this final mass, after setting and drawing, can "be reduced to a dry, homogeneous and stable powder, not hy- gyroscopic, using a suitable grinder.
According to the present invention, in this process sulfuric acid is replaced by nitric acid, so that a complete dissolved fertilizer based on nitric nitrogen is obtained.
The present invention pursues the following aims:
1 Make a fertilizer giving the plant complete nourishment, that is to say providing at the same time and in such an assimilable form: nitric nitrogen, ammoniacal nitrogen, phosphoric acid, potash, lime.
2 To provide the plant with these various essential elements, not only in the form of a completely adequate assimilation to plant nutrition, but also in a state of complete homogeneity. In fact, in compound fertilizers produced by mechanical mixing, the particles of the different mixed fertilizers are not intimately united. Some fertilizer distributors, even distributors based on centrifugal force, operate by spreading, a mechanical separation of the elements, which makes their distribution very irregular.
3 Make a fertilizer, the reaction of which is in no way acidic, which is even alkaline or at least neutral.
4 Make a very dry and fine fertilizer, the distribution of which to the mechanical distributors is easy, adjustable at will and very regular.
5 Make a non-hygroscopic fertilizer, which retains all its intrinsic fertilization qualities, and
<Desc / Clms Page number 3>
more, its ease of spreading, thanks to its dryness.
The following raw materials are used in the manufacture of complete dissolved nitric fertilizer:
1 nitrogen in the form of ammonium sulfate;
2 nitrogen in the diacid form of nitric acid;
3 phosphoric acid in the form of mineral phosphate and superphosphate;
4 Potash in the form of chloride or sulphate of potash.
The phosphates are ground to as great a fineness as possible and at least a fineness of 85% with a N 100 sieve
The sulphate of ammonia and the chloride of potash are ground rather summarily, being easily solubilized in nitric acid.
The phosphate is introduced into the mixer followed by the ammonium sulphate and the mixture of water and nitric diacid, the latter attacking the phosphate. in order to increase the content of water soluble p 2 i5, a specified proportion of superphosphate is added thereto. it is stirred for some time, then one introduces the potash of chloride or the potash of sulphate.
.after intimate mixing, the mass is discharged from the mixer by opening a drain valve. The liquid product at this phase falls into the cellar. After a few hours' stay, the cava can be emptied.
The fertilizer is then disintegrated and the product is placed in the store for drying in the open air.
The product obtained enjoys the same advantages as the ordinary dissolved complete fat mentioned in the main patent.
