| 摘要 |
The present invention relates to a milling and water-air combined cooling system for bottom ash from heating furnaces for solid fuels, able to maximize the efficiency in milling and cooling also large ash lumps at high temperature and in improving cooling air fluid dynamics which passes said system in counter-flow. The system comprises a crusher (1) a toothed rotor (9) with milling elements, provided with a pre-crusher integral with the crusher's (1) port, a water cooling system (3-4), and an opening for fine material made at the rear wall of the crusher (1) arranged so as to avoid its crossing with the rotor milling elements and separated from the opening for ash lumps. |
