| titleOfInvention | By the method that vertical furnace calcines mud, waste gypsum produces belite-gypsum material |
| abstract | By the method that vertical furnace calcines mud, waste gypsum produces belite gypsum material, comprise the following steps: high-moisture-contensludge sludge ridge grain crystal seed is turned to modified sewage sludge slag by (1)；(2) by modified sewage sludge slag and waste gypsum, barren rock slag and correction material, carry out two-stage raw meal proportioning and homogeneous, dispensing and homogeneous add the fire coal of proper proportion according to a certain ratio, be shaped to particle or charge bar, obtain black meal and shape material；(3) gained black meal molding mass is sent in vertical furnace, in 1250 DEG C ~ 1400 DEG C, be grog by the calcining of black meal molding mass；(4) gained chamotte powder is worn into powder.The inventive method is simple, invests little, low cost, both scale, resource can dissolve mud and waste gypsum, and again without other secondary pollution, also can save a large amount of energy consumption, alleviate environmental pollution. |
