A METHOD OF PREPARING A DENSE PELLETIZED COMPOSITION, WHICH COMPRISES, SUSPENDING SOLID SEED PARTICLES HAVING A PARTICLE SIZE OF A LEAST ABOUT 0.006 INCH IN A STREAM OF AN ESSENTIALLY DRY, NONREACTIVE FLUIDIZING GAS SO AS TO FORM A FLUIDIZATION ZONE, CONTACTING SAID SEED PARTICLES WITHIN SAID FLUIDIZATION ZONE WITH A SPRAY OF LIQUID, MOLTEN MATERIAL WHICH IS A SOLID AT AMBIENT TEMPERATURE, THE TEMPERATURE OF SAID SPRAY OF LIQUID MOLTEN MATERIAL BEING ABOVE THE SOLIDIFICATION TEMPERATURE OF SAID MATERIAL, THE TEMPERATURE OF SAID FLUIDIZATION ZONE BEING AT LEAST ABOUT 10*F. BELOW THE SOLIDIFICATION TEMPERATURE OF SAID MOLTEN MATERIAL, SAID LIQUID MOLTEN MATERIAL BEING SELECTED FROM THE GROUP CONSISTING OF: (1) SODIUM HYDROXIDE CONTAINING ABOUT 24 TO 38% BY WEIGHT OF WATER; (2) SODIUM METASILICATE PENTAHYDRATE CONTAINING ABOUT 10% BY WEIGHT OF SODIUM METASILICATE PENTAHYDRATE FINES; (3) ANHYDROUS CALCIUM CHLORIDE; (4) ANHYDROUS ALKALI METAL HYDROXIDE; (5) ALKYLENE OXIDE ADDITION PRODUCT WITH AN ORGANIC COMPOUND HAVING AT LEAST ONE ACTIVE HYDROGEN ATOM; (6) ISOCYANATE - TERMINATED, POLYETHER - BASED POLYURETHANE INTERMEDIATE; (7) HYDROXYL-TERMINATED, POLYETHER-BASED POLYURETHANE INTERMEDIATE; (8) ISOCYANATE - TERMINATED, POLYESTER - BASED POLYURETHANE INTERMEDIATE; AND, (9) HYDROXYL-TERMINATED, POLYESTER-BASED POLYURETHANE INTERMEDIATE; SAID SEED PARTICLES BEING THE SAME MATERIAL IN SOLID FORM THAT IS EMPLOYED AS SAID MOLTEN MATERIAL AND DEPOSITING SOLIDIFIED MOLTEN MATERIAL ON SAID SEED PARTICLES TO PRODUCE SAID DENSE PELLETIZED COMPOSITION.
