利用电厂粉煤灰、炉底渣及脱硫石膏粉磨水泥工业化技术研究

Industrialized Technology Research on Using Power Plant Fly Ash,Furnace Bottom Ash and Flue Desulphurization Gypsum to Grind Cement

利用燃煤电厂粉煤灰、炉底渣及脱硫石膏等废渣为原料,采用辊压机+分级打散机+开路高细磨的粉磨流程生产P·C32.5和P·F32.5水泥;水泥配合比中电厂废渣掺量达45%,其中粉煤灰、炉底渣掺量按质量百分比达到国家标准规定的上限;水泥单位产品可比综合电耗低于国家标准的先进值。

P · C32.5 and P · F32.5cement is produced by using coal-fired power plant fly ash, furnace bottom ash, flue desulphurization gypsum as raw material with the grinding process of using roll- er press machine, grading broken machine and open stream high-fine grinding machine. The percent- age of power plant waste ash in cement mixture proportion is as high as 45% ,and the mass percent- age of fly ash ,furnace bottom ash reaches the upper limit of national standard. The comparable inte- grated power consumption of unit cement product is below the advanced value of national standard.
