HARDENING GRANULATED MATERIAL |
摘要 |
A mixture of inorganic binder, water and fly ash is granulated; the formed granules (7) are deposited upon a continuously supplied layer of fly ash embedding material (9) and said fly ash layer together with granules is fed into a hardening reactor (14). The granules are hardened by injecting steam (16) into the reactor so that the temperature of the granules is raised and maintained at a temperature comprised between 50 and 100 DEG C. After curing the hardened granules are separated from the embedding material which is used for forming new granules. The embedding material has a water absorbing capacity of 15-25% and the pH of the moist embedding material is above 4. |
