PROCESS FOR THE PRODUCTION OF AMMONIUM SULFATE GRANULES USING A CONCENTRATED SOLUTION OF AMMONIUM SULFATE

摘要

THE INVENTION CONCERNING PASTILLAGE OF AMMONIUM SULFATE. ONLY SUBMITS AMMONIUM SULFATE SOLUTION TO ATOMIZATION DRYING AND THEN GRANULATES USING SOLUTION AS AQUEOUS MEDIUM. CONCENTRATED WITH AMMONIUM SULPHATE, FINALLY DIVIDED SULFATE PREVIOUSLY OBTAINED ON THE NEXT DRAFT AND STILL SUBJECT TO SHORT HEATING. / P P THE SULFATE OBTAINED HAS A GOOD RESISTANCE TO COMPRESSION AND WEAR. IT MAY BE MIXED WITH OTHER CONSTITUENTS OF MINERAL FERTILIZERS TO BE DIRECTLY SUPPLIED TO THE USER, AND TO STILL REMAIN AFTER EXPEDITION AS A MIXTURE READY TO SPREAD. / P
