<p>PROBLEM TO BE SOLVED: To provide a regeneration treatment method for coating material waste capable of forming powder having a low moisture content with a simple equipment. SOLUTION: The regeneration treatment of the coating material waste is executed by first spreading and placing the coating material waste 4 on trays 5, in a drying chamber, arranging these trays on stacking shelves 6 and blasting air of ordinary temp. under low humidity thereto by a drying machine 2 to expose the coating material waste to this air, thereby drying the coating material waste. When the coating material waste 4 dries to some extent, the coating material waste is taken out and is crushed. The crushed coating material waste is again arranged in the drying chamber 1 and is further dried by exposing the coating material waste to the air of ordinary temp. under low humidity. The dried and crushed coating material waste is taken out and is pulverized, thereby, the powder having an extremely low moisture content is obtd.</p> |
