IN A ROTOR (1) PROVIDED WITH A PUNCHING METAL NET (2) WHICH CAN SUPPLY A MOLTEN AND MIXED RESIN COMPOSITION TO AN UPPER PORTION OF THE ROTOR (1) FROM AN OPENING PORTION AND IS FORMED BY A MAGNETIC MATERIAL ON AN OUTER PERIPHERY THEREOF OR IS FORMED BY A NONMAGNETIC MATERIAL BEING CONTACT WITH A MAGNETIC MATERIAL (3), THE RESIN COMPOSITION IS GRANULATED INTO POWDERS OR IN A FIBER SHAPE BY HEATING THE MAGNETIC MATERIAL PORTION SO AS TO PASS THE RESIN COMPOSITION THROUGH SMALL HOLES IN THE UNIFORMLY HEATED PUNCHING METAL NET (2) DUE TO A CENTRIFUGAL FORCE, AND THE GRANULATED POWDERS ARE TRANSFERRED BY AN AIR FEEDING APPARATUS (12) HAVING A ROTARY BLADE (11) MOUNTED THEREIN FROM A DISCHARGE PORT IN A LOWER PORTION OF AN OUTER TANK (8). ACCORDINGLY, SINCE THE RESIN COMPOSITION IS PULVERIZED INTO THE POWDERS HAVING A PARTICLE DIAMETER CLOSER TO A PARTICLE DIAMETER OF A FINAL PRODUCT AT A TIME OF BEING COLLECTED IN A PRODUCT RECOVERY CONTAINER (13) THAN A PARTICLE DIAMETER OF THE POWDERS IMMEDIATELY AFTER BEING GRANULATED, A COOLING OPERATION IS PROMOTED AND IT IS POSSIBLE TO REDUCE A PULVERIZING TIME AND REDUCE FINE POWDERS AND COARSE POWDERS GENERATED AT A TIME OF A PULVERIZING STEP WITHOUT DETERIORATING A CHARACTERISTIC OF THE RESIN. THEREFORE, IT IS POSSIBLE TO ACHIEVE A GRANULATING APPARATUS OF A RESIN COMPOSITION WHICH CAN REDUCE A CLASSIFYING STEP OR SAVE LABOR AND TIME.(FIG 1)
