Process for producing mixed ammonium nitrate

Claim 1

THE PROCESS OF MAKING A MIXED SOLID FERTILIZER PRORUCT IN THE FORM OF A CRYSTALLINE MATRIX OF SOLID AMMONIUM NITRATE IN WHICH SUBSTANTIALLY DISCRETE PARTICLES OF FINELY DIVIDED SOLID SOIL ADDITIVE SELECTED FROM THE GROUP CONSISTING OF CALCIUM CARBONATE, MAGNESIUM CARBONATE, AMMONIUM SULFATE, CALCIUM SULFATE, SODIUM NITRATE, SUPER PHOSPHATE, TRIPLE SUPER PHOSPHATE, POTASSIUM NITRATE, LIMESTONE AND THEIR MIXTURES ARE IMBEDDED THEREIN WITH CONSISTS ESSENTIALLY OF CONTINUOUSLY PRODUCING SUBSTANTIALLY ANHYDROUS MOLTEN AMMONIUM NITRATE WITH A TEMPERATURE GREATER THAN 337*F., CONTINUOUSLY AND UNIFORMLY MIXING IT WITH A PREDETERMINED AMOUNT OF FINELY DIVIDED SUBSTANTIALLY DISCRETE PARTICLES OF SAI SOLID SOIL ADDITIVE AT A TEMPERATURE AT WHICH THE SULTANT MIXTURE WILL REMAIN IN A FREELY FLOWING CONDITION, SAID SOLID SOIL ADDITIVE HAVING BEEN PREHEATED TO PREVENT SUBSEQUENT UNDESIRABLE THICKENING OF THE RESULTANT MIXTURE, THEN FLOWING THE FLUID MIXTURE OF SAID SOLID ADDITIVE IN MOTLEN AMMONIUM NITRATE ONTO A MOVING FLAT ENDLESS COOLING BELT AT A RATE SUFFICIENT TO COOL AND SOLIDIFY THE MIXTURE BEFORE DISCHARGE FROM THE BELT AS A MECHANICAL MIXTURE IN THE FORM OF CRYSTALS WITHOUT SETTLING OF THE SOLID PARTICLES AND WITH THE PARTICLES UNIFORMLY IMBEDDED THEREIN AND COMMINUTING THE CRYSTALLINE MASS TO PREDETERMINED PARTICLE SIZE.
