METHOD FOR MANUFACTURING REGENERATED PARTICLES

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing regenerated particles capable of suppressing the decomposition of calcium carbonate and capable of enhancing the quality of the regenerated particles.

SOLUTION: The method for manufacturing the regenerated particles by dehydrating, drying and combusting a raw material 10 has the step of continuously drying and combusting the raw material 10 after dehydration under an oxygen atmosphere of 0.05-20% in a first combustion furnace 14 and the step of again combusting the raw material 10 passed through the drying and combusting step in a second combustion furnace 32 separate from the first combustion furnace 14. A kiln together using external heat 31 and internal heat 40A is used as the second combustion furnace 32.
