Project Name: Sanming Jinniu Cement Cement Kiln System Energy-saving and Consumption-reducing Technical Transformation
Enterprise and Partner Name: Sanming Jinniu Cement Co., Ltd.
Main Construction Content: 0 HTML0UN K7 In this project, the cement process system will be technically transformed: 0 HTML0 UNK8 1.1 # and 2 # cement mills will be added with compound mineral powder to reduce the usage of 0 HTML0 UNK9 clinker 0 HTML0 UNK1 0; 0 HTML 0 UNK1 12. The technical transformation of changing the dust collector bag at the kiln end, after the technical transformation, the dedusting ventilation area is increased, the resistance is reduced, and the power consumption is saved; 0 HTML 0 UNK1 23. The solid waste dedusting powder is directly mixed and calcined at the kiln end, the use amount of raw meal powder is reduced, and then the use amount of raw material limestone is reduced, and the energy is saved; 0 HTML0 UNK1 3 4. that raw material is directly mix with the aluminum ash for calcination, because the main component of the aluminum ash, Al 0 HTML0 UNK1 4 20 HTML0 UNK1 5 0 HTML0 UNK1 6 30 HTML0 UNK1 7, can be used as clay, thereby reduce the use of the raw material of the raw material and saving the energy consumption of the raw material; 0 HTML0 UNK1 85. Kiln tail exhaust fan energy-saving transformation; 0 HTML0 UNK1 96.1 # cement mill production energy-saving transformation; 0 HTML0 UNK2 07.
