Przy produkcji saletry potasowo-amo- nowej znana- jest .metoda, polegajaca na rozpuszczaniu czesci) chlorku potasowego w .goracym stezonym roztworze azotanu amonowego i poddawaniu rozpyleniu tak przygotowanej plynnej masy. Druga cz;esc chlorku potasowego rozpylano oddzielnie do komory luib tez mieszano w zwyczajny sposób mechaniczny. Mejtoda ta ma naste¬ pujace zle stromy, ze 1.) rozpuszczanie cze¬ sci chlorku potasowego w stezonym roztwo¬ rze azotanu amonowego zageszcza mase, czyniaic ja trudna do rozpylenia, 2) wpro¬ wadzanie reszty chlorku potasowego wy¬ maga oddzielnego urzajdzenia do jego roz¬ pylenia, 3) w razie oddzielnego rozpylenia otrzymuje sie produlct o zle wymieszanych skladnikach, co utr/udnia przebieg reakciji, majacej na celu utworzenie chemicznej so¬ li podWójnej.Wynalazek niniejszy unika wymienio¬ nych wad. Nowa metoda wytwarzania sale¬ try potasowo-amonowej przez rozpylenie 'do isuJchosfci polega na tern, ze sproszkowa¬ na calkowita ilosc chlorku potasowego ewentualnie, juz podgrzana do temperatury •powyzej 100° C, doprowadza sie do stezo¬ nego goracego roztworu isaletry amonowej w mieljlscu jej bezposredniego splywania do Ir o-zjpyil a j ae ego strumieni a powietrza.Nastepujacy przyklad blizej wyjasnia zastosowanie omawianej metody.

PLIn the production of ammonium nitrate, there is a known method of dissolving a part of the potassium chloride in a hot concentrated ammonium nitrate solution and spraying the prepared liquid mass. The second part of the potassium chloride esc was sprayed separately into the chamber or mixed in the usual mechanical manner. This method has the following bad steepness, that 1.) the dissolution of a portion of the potassium chloride in a concentrated ammonium nitrate solution thickens the mass, making it difficult to spray, and 2) the introduction of the rest of the potassium chloride requires a separate device to it. spraying, 3) in the case of separate spraying, a product with poorly mixed components is obtained, which prevents the course of the reaction aimed at creating a chemical double salt. The present invention avoids the above-mentioned disadvantages. A new method for the preparation of potassium-ammonium salt by spraying into an ammonium chloride is that the powdered total amount of potassium chloride, possibly already heated to a temperature above 100 ° C, is fed to a concentrated hot solution of ammonium chloride in the grinding mill. Its direct flow to Ireland was eaten by a stream of air. The following example explains the application of the method in question. From the reservoir a, which maintains a concentrated (about 90%) solution of ammonium nitrate at a temperature of about 120 ° -130 ° C, the mass flows and the gutter b is uniformly located. The following factors are: the poison of the atomizing air. Potassium chloride, evenly distributed over the entire width of the gutter, will be assisted by the technology of the equipment that is provided, which is distributed evenly over the entire width of the gutter. Experience has shown that the application of the above method not only simplifies the production of ammonium-potassium nitrate, but also gives a very homogeneous product in a ground form.
